Machine Vision 4 Users: Sometimes you just have to vent

http://machinevision4users.blogspot.com/2015/06/sometimes-you-just-have-to-vent.html

Tuesday, June 9, 2015. Sometimes you just have to vent. What I didn’t realize though is that venting can improve the way your hardware performs. I bet you’re surprised by that too but it must be true. Why else would Gore, (yes, the people who make GORE TEX fabrics,. Run a webcast called, “Enhancing Sensor Reliability Through Venting”? I learned about this from an email. I couldn’t find anything on their website ( http:/ www.gore.com/en xx/products/venting/index.html. Posted by B Grey. Dr Lau, 3D Guru.

Accelerated Image Processing: Fast Pattern Features

http://visionexperts.blogspot.com/2013/01/fast-pattern-features.html

Experience with Machine Vision, Image Processing and Computer Vision Algorithms. Friday, 11 January 2013. Inventing really fast pattern matching algorithms is good fun. Performing image correlation is slow, but it can be accelerated by not using every pixel. The algorithm I'm using splits a high resolution trained template image into multiple small feature patches. Only the best patches that have the highest structure tensor are then used for alignment ( Figure 1. Different from the correct match positio...

Accelerated Image Processing: July 2010

http://visionexperts.blogspot.com/2010_07_01_archive.html

Experience with Machine Vision, Image Processing and Computer Vision Algorithms. Friday, 23 July 2010. Blazingly Fast Image Warping. Want to achieve over 1 Gigapixel/sec warping throughput? Then leverage your GPU texture units using CUDA. There are several good reasons to use the texture hardware from CUDA when image processing:. Texture fetches are cached. For CUDA array memory, the texture cache has a high level of 2-D locality. Texture fetches from linear memory are also cached. The developer had to m...

Machine Vision 4 Users: Should we hold a caption contest?

http://machinevision4users.blogspot.com/2015/05/should-we-hold-caption-contest.html

Sunday, May 31, 2015. Should we hold a caption contest? The big Automate show has come and gone, but it lives on forever online. As you may know, Vision Systems Design magazine presented awards for special achievement in the machine vision realm at the show. What you may not know is that there is a slideshow of these presentations on the www.vision-systems.com. So I think we should have a caption contest. Let’s see who can come up with the most amusing speech bubbles. Send me an edited/mark...If you'd li...

Machine Vision 4 Users: Job for a rule-loving engineer?

http://machinevision4users.blogspot.com/2015/06/job-for-rule-loving-engineer.html

Tuesday, June 16, 2015. Job for a rule-loving engineer? As an engineer you don't have much of a career path, unless you want to go into management. (I advise against it.) So as a way of recognizing professional seniority and competence the role of Principal Engineer was created. In this context, “Principal” implies head or most senior. Every so often though, I see jobs advertised for “ Principle Engineer. Posted by B Grey. Subscribe to: Post Comments (Atom). Friends worth checking out. Dr Lau, 3D Guru.

Machine Vision 4 Users: Camera interface standards

http://machinevision4users.blogspot.com/2015/06/camera-interface-standards.html

Thursday, June 4, 2015. Y impression that the machine vision industry has pretty much standardized on one interface. It’s GigE for area or matrix cameras, leaving USB3 to the scientific/medical community and falling back on CameraLink for linescan applications. (Though I notice Dalsa now has a family of GigE linescan cameras. However, I know other industries like other formats. 8221; I didn’t expect to learn much. But there were a couple of interesting snippets. Large connector and interface driver.

Machine Vision 4 Users: Machine vision education

http://machinevision4users.blogspot.com/2015/06/machine-vision-education.html

Sunday, June 14, 2015. Every so often a reader finds my blog while trying to teach themselves about machine vision. Then I get a very nice email, (I love getting emails – it shows you actually read my rambling thoughts,) asking where they can find good educational material. It’s difficult. There are textbooks, like Nello Zeuch’s “ Understanding and Applying Machine Vision. Posted by B Grey. Subscribe to: Post Comments (Atom). Friends worth checking out. Compressed Sensing - whatever that is. If you'd lik...

Machine Vision 4 Users: Why GenICam 3.0 deserves your attention

http://machinevision4users.blogspot.com/2015/06/why-genicam-30-deserves-your-attention.html

Thursday, June 18, 2015. Why GenICam 3.0 deserves your attention. Some engineers love standards. They get all excited about reading them, and positively orgasmic when offered the chance to be on a standards committee. 8221; this explains how EMVA has standardized interfaces for 3D cameras in the same way as 2D cameras have been standardized for some years. Also in the new release, some enhanced point-cloud capabilities. Learn more by reading the press release. Posted by B Grey. July 5, 2016 at 8:47 AM.
