Corn going through an “ugly” stage

first_imgShare Facebook Twitter Google + LinkedIn Pinterest With the way the 2017 Spring planting season shaped up, farmers are on edge and may not have high hopes when they are out scouting fields. DuPont Pioneer Account Manager Chasitie Euler says corn may not look very good now, but there is a reason for that. She also says to be on the lookout for insect feeding this time of year. The Ohio Ag Net’s Ty Higgins has more in this week’s DuPont Pioneer Field Report.last_img

Smoke ConnectFX Nodes: Edge Detect, Filter, Flip, and Field Merge

first_imgThe Edge Matte node can also be found in the Modular Keyer. It’s here where pulling edge mattes can aid in creating Light Wrap effects with your keys…or aid in making cleaner composites.[Click for larger image]Blurring your image a bit can also effect the edge detection as more blur will create fewer edges created. This will allow you to focus on the main edges in an image and not all of the details in the image that can get in the way of creating the edge you want.Smoke’s Field MergeThe Field Merge Node is very simple. When dealing with interlaced clips, you can blend the fields together, essentially creating a progressive clip. This differs from the Deinterlace Node in that it doesn’t split the fields or lengthen the clip. It can also reduce field flicker in an interlaced clip. You can set the value at 100% for complete blending or less if needed.Field merge will soften the image, as you are blending moving fields, so the adjustment will help give you the best result. I often use field blending to create a “film-look” effect as it helps to lessen the “video” look of an image.[Click for larger image]Smoke’s Flip NodeThe Flip Node performs a very simple Flip of your image along the Vertical or Horizontal, or Both Axis. When you flip a clip vertically, you may need to reverse the fields so that the clip plays back in the proper field order.There are many other ways to flip a clip in X or Y, so why would you use this node over 2D Transform or through Action? On my MacbookPro setup, I found no difference in rendering speed between the Flip Node, 2D Transform, Action, or Axis on the timeline. This is an older node, which is why it still exists in the bin. It is fast. When you just need to flip a shot that might be in the middle of a large CFX node schematic you can just pop the node into the flow.[Click for larger image]Smoke’s Filter NodeThe Filter Node uses old school mathematical matrices on a per pixel bases to perform image processing like Blurs, Edge Detection, and Emboss to a clip. Most of the effects that you can do with the Filter Node can be done better and with more flexibility in other nodes. There are many presets you load to see how the effects are applied. The basic understanding of how a Matrix operation works is that a grid is placed around each and every pixel. The grid can be as small as 3×3 or as large as 11×11. The operation replaces each pixel with the weighted average of the pixels around it, where the weights are given by the matrix.A Matrix that looks likes this produces no change in the image.To be honest, this type of image processing was great in the 1990’s, but it has long since been practical. Smoke’s other nodes like Blur, Glow, & Bump Displace are tools built in the modern era. I am sure some old school users relied heavily on this node in the past, but not anymore. It’s my guess that this is a node you won’t ever use. If you are mathematically inclined, you may find more creative uses as you can define your own pixel comparison matrices. If you look through the presets you can find a few of the settings that still produce a unique look. Check them out and see if you can find some use for them. When dealing with softer video shot with DSLR and compressed to H.264, I do find the Sharpen Filter does do a nice job of making the edges crisper.[Click for larger image] In this post we explore more nodes inside Autodesk Smoke ConnectFX. In this Smoke tutorial we’ll show you how to use Edge Detect, Filter, Flip, and Field Merge nodes in your editing projects.This week we blitz through some simple nodes inside Smoke’s node-based compositing environment – ConnectFX. Edge Detect and Filter are the more creative tools, whereas Flip and Field Merge are more utility operations. Some nodes you may only use once year. Other nodes you use every day. In our series on Smoke ConnectFX nodes we’re breaking down how each node works and what you can do with it. So, when you need to do that ‘one thing’ you’ll know what node to use!Smoke’s Edge DetectThe Edge Detect Node will define an edge and output a matte for that edge for use further down your ConnectFX schematic. The edges are based on colors and luminance between pixels. You can choose to define edges based on RGB, HLS, Chroma, or Mono.[Click for larger image]You can set the Result output as the composite of the input image with the matte generated by the edge detection. Or, select Edge Only to output only the result of the matte generated by the edge detection. You can also choose what to output from the nodes matte output. You can choose to simply pass the original input matte through or output the created Edge Matte effect. The Edge Detection settings area is where you define the edge based on the input image. You can adjust the weight of the individual Red, Green, Blue channels. Changing these values form 100% will increase or decrease how much of that channel is being used to define the edge. In RGB, HLS, and Chroma settings, it will adjust the color of the edges created. The Threshold setting can be set for the minimum and maximum values. Think of it like the min/max settings of the 2D Histogram. The Softness setting in this area is adjusting the width of the softness between edges in your image and the gain of that softness. It will blur the edge matte and increase the luminance of it.In the Edge Effects area you can create a Double Edge which will perform a second pass of the edge detection. There are more min/max settings and Softness settings affecting the Double Edge. You can skew the softness in a direction by activating the direction button and setting the angle. This can act like a change in lighting on the generated edge matte.You have Color controls inside this node. These controls color the edge matte even further, increasing or decreasing colors.With the Use Matte button enabled, you can choose common blend modes with transparancy, used with the color correct controls to create edge effects in your image.center_img Follow all of our coverage of the new Autodesk Smoke.

All you need to know about Dhola-Sadiya Bridge, India’s longest river bridge

first_imgPrime Minister Narendra Modi takes a walk on the Dhola-Sadiya bridge over the Brahmaputra in Assam after inaugurating it on Friday. Photo courtesy: Twitter/@PMOIndia 4. It is 3.55 km longer than the Bandra-Worli sea link in Mumbai. The sea link has now become the second longest river bridge in the country.5. The construction of the Dhola-Sadiya bridge began in 2011 by the Ministry of Road Transport along with Navayuga Engineering Company Ltd., under the public-private-partnership agreement6. A sum of ₹ Rs 2,056 crore has been spent on the bridge that can withstand 60 tonnes of weight, including battle tanks.7. The bridge, which has a three-lane carriage way, will also cater to the strategic requirements of the country in the border areas of Arunachal Pradesh, besides facilitating numerous hydro power projects coming up in the State, as it is the most sought after route for various power project developers.8. The bridge will make it much easier for Army convoys to reach outposts near the China border. It is also expected to boost tourism as there is no civilian airport in Arunachal Pradesh and this will make the road transport smoother.9. The bridge will increase industrial investments with better border trade between the Northeast and South Asian countries.10. State-run SAIL is the largest supplier of steel for the bridge. The PSU has supplied around 90% or around 30,000 tonnes of steel, including TMT, structurals and plates, for the bridge. Prime Minister Narendra Modi on Friday inaugurated the Dhola-Sadiya Bridge in Assam, which is India’s longest river bridge.Here are 10 things to know about the bridge:1. Spanning 9.15 km, the bridge is built across the Lohit river, which is a tributary of the Brahmaputra. It will connect Assam and eastern Arunachal Pradesh. The total length of the project, including the approach roads on each side, is 28.50 km.2. The bridge is located 540 km from Assam’s capital Dispur and 300 km from Arunachal Pradesh capital Itanagar. It connects Sadia town in Assam’s Tinsukia district with Dhola village, also in Assam.3. The bridge will reduce the travel time between Assam and Arunachal Pradesh from six hours to just one hour as the distance will shrink by 165 km.last_img read more

Proposed refinery for Northern Gateway bitumen gets cold shoulder from BC First

first_imgAPTN National NewsVANCOUVER–A proposed refinery to handle Alberta bitumen pitched by a British Columbia businessman is just “another pipe dream” and a “ruse” to increase support for the Northern Gateway pipeline according to a spokesperson for an all alliance of First Nations along the province’s northern and central coast.Art Sterritt, executive director of Coastal First Nations, says the refinery, pitched by newspaper tycoon David Black is a “shot in the dark” to try and revive flagging support for the Enbridge’s Northern Gateway Pipeline.“All kinds of people are having pipe dreams out here,” said Sterritt. “We look at it as another ruse to try to get support for Northern Gateway.”Black, who owns Black Press Ltd., announced Friday he would be willing to pay for the environmental assessment of a $13 billion refinery, but needed financial backers to make the project a reality. The proposed refinery would be built near Kitimat, B.C., which is the endpoint for Enbridge’s proposed $5.5 billion pipeline.Black told the Vancouver Sun that the refinery would solve concerns over having bitumen-laden tankers moving through the environmentally sensitive Douglas Channel. He said the proposal would soften First Nations opposition to the pipeline by erasing the environmental threat to the coast of B.C.Sterritt, however, said Black never really consulted with any First Nations about the project before announcing it on Friday and the proposal would do nothing to mitigate the threat of a ruptured pipeline which would still cross several major watersheds on its trip from Alberta’s tar sands.Sterritt said already existing refineries in the Vancouver area have reduced their capacity because it’s more lucrative to ship raw product overseas. The existing Kinder Morgan pipeline was constructed 40 years ago on the promise of jobs created by refining activities.“We already have a pipeline that is going to the Vancouver harbour, but those people shipping bitumen and other crude oil have decided they can make more money overseas than refining and they have shut down refining in B.C.,” he said. “Historically, this pipeline was built on the back of the refineries, so the people of B.C. said, ‘We’ll allow the pipeline to go through, we need refined product in B.C.’ Since then, they’ve backed off.”Haisla First Nation Chief Councillor Ellis Ross said Black contacted one of his advisors on Thursday to inform the Haisla about the planned announcement. Ross said Black has toyed with the proposal for some time, but the Haisla have never been consulted on the issue or seen anything official on paper about the refinery project.“It was unofficial contact, there was nothing on paper, no consultation it was just a concept,” said Ross. “What I made clear is the idea that our people have mandate to have absolutely no bitumen or crude oil on Haisla territory.”Ross, however, said he hoped Black’s proposal would finally focus the debate about the Enbridge pipeline on the lack of existing refining capacity in the country versus shipping off raw product overseas only to buy it back later at a higher price.“It’s the white elephant in the room. The focus has entire been to get the product to Asia,” said Ross. “It’s like shipping raw logs to Asia and buying back the product at 10 times the price.”news@aptn.calast_img read more
