Distributed vs Centralized

Ann, this is an interesting contrast to the article from August 13, by Al Presher, titled "Blurring the Lines of Control".  In that article, the machine control system integrated image processing with other functions in a centralized computer.  As I commneted then, this is going against the trend in the industry, as mentioned in this article, for distributing the intelligence.  For example, a modern automobile has probably 50 or more processors.  Genreally there is even a processor for the temperature guage.  It is cheaper to do that than to integrate software on a centraized machine.  In addition, it is generally more accurate when performing control functions to have the processing near the device. 

I am looking forward to Jeff's course as well.  It should be interesting.

Lou, glad you will be joining us. In the time I spent reporting on machine vision, I discovered that there really isn't a single MV industry anymore, and within it there are multiple trends, sometimes apparently opposite ones. While some vision system/production system designers are shifting more toward distributed control, others are moving toward centralized control. And these differences exist not only between application clusters within traditional industrial machine vision, but within them, too. It all depends on what the vision system is being required to do and what constraints there are on it. At a larger scale, the formation of the EVA made it clear that things are even more complex when you go outside industrial machine vision and look at other uses of embedded computer vision.

I've seen an earlier version of this presentation and it's quite exciting. When you learn all the things that not only possible, but extremely cost effective, it's mind boggling. I plan to attend.

Ann, thanks for posting this.  I was wondering if it would be worthwhile for me to join; with the list of topics being covered, it will definitely be a good course.

Thanks @Ann! Embedded Vision is a very timely topic. With inexpensive vision sensors being place in all sorts of devices we are moving beyond the technology of "how can we do this?" and into "how can we use this?" ...and soon after "why do we need this?". One of the largest immediate impacts will be its disruptive effect on police sketch artists and eyewitnesses. With every action digitally recorded, we will move quickly away from the "he said", "she said" impasses of yesteryear. 
 
On the positive employment side, the demand for "video-photo-shoppers" will skyrocket, both for vanity's sake and for those underworld characters that have enough money to alter the photographic record.

williamlweaver, glad you will be joining us. I think that's an intriguing point about all the photoshopping of the (soon-to-be) massive amounts of online photos. Might make a good question for our lecturer.
