Here we describe a novel low-cost flow cytometer based on a webcam capable of low cell number detection in a large volume which may overcome the limitations of current flow cytometry.
Several key elements have been combined to yield both high throughput and high sensitivity.
I have a need to take an image of a series of glass test tubes, and automatically give an indication of either the level fo liquid in the tubes or the point at which the liquid reaches the bottom of the tubes.
The image would probably be gathered by a webcam and processed on a standard PC.
But, creepiness aside, are there actual risks associated with, say, someone in a remote location tuning in to a baby monitor?
"When you think about the real-world risks, you have to reach pretty far to find something that would be genuinely bad," said Anton Chuvakin, security and risk management researcher at Gartner.
Possibly illuminating the tubes from the back could make sense.
There might be other ways, but my restrictions are that I will have multiple tubes (around 12-24), the liquid will be clear and needs to stay contamination free (one current solution it to sense the liquid level using a resistance probe that moves, but it's slow and causes contamination headaches...) Chesnokov-Yuriy wrote series of articles explaining image analysis in codeproject. some of his articles, you can find useful If you do it with image analysis, the first thing is to get the best possible image quality.
The Logitech C615 HD Webcam allows you to capture full HD video, make high quality video calls and even take high resolution photos.
It has a versatile and compact design which is perfect for taking on the go so you'll be able to capture high quality video anywhere.
Shodan's home page touts the service as "the search engine for power plants, refrigerators and webcams," among other things.
Matherly was quick to point out that the company is not specifically focused on webcams.
This Logitech C270 HD Webcam allows you to add video functionality to your laptop or desktop computer.
