My primary goal for this blog is to share hints and tips that make it easier to use machine vision. Of course the challenge is that many developers consider such information proprietary but every so often I come across someone man enough to share.
The latest example, “Automating Particulate Inspection: More Than Meets the Eye,” (undated) comes from PharmaManufacturing.com and covers, as the title suggests, the tricky business of detecting small particles.
The author, Josh Capogna of Mcrae International, begins by summarizing the deficiencies of human inspection – a subject dear to my heart – before launching into a fairly detailed discussion of particle detection scenarios. The one I found most interesting was looking for clear particulates in a clear container. I don’t want to spoil your enjoyment of the article but I can’t resist sharing this particular snippet: the approach is to shake up the container and use motion tracking to identify particulates as they move through the liquid.
That’s an idea that I shall be filing away for future use.

Greetings :)
I'm glad you find the idea useful! The real trick is to find the right agitation method since large bubbles are no big deal to filer out but sometimes very small bubbles actually float down and are identified as particulate. Also, agitation method can make the difference between a $200K machine and a $2M machine.
Thanks for reading!
Josh C.
