 | | Software to merge video frames to obtain higher quality stills? —Richard Franks
|
| | | I got a cheap webcam (~$60), and it is okay, but a bit grainy. I just want to take still pictures of LEGO, so I reckon that it should be possible to take X frames a second and merge them into one, eliminating the grain and getting a nice clear (...)

If you're really trying to go overboard, it's not that hard to write a matlab program to filter out single pixle noise, using a simple 3x3 (...) (25 years ago, 12-Apr-00, to lugnet.publish)
