2015-06-06 13:20:50 -0600 | asked a question | Pixel Subraction + Gain - Realtime Video Hello, I need to write a program for real-time processing a laser interferometer video image. The processing is fairly simple, and similar to background detection. I need the real-time display of one video frame subtracted from the previous frame (with no compression or other alterations of the pixel data from the camera), and with a variable gain (i.e. the result multiplied by perhaps 1 - 20). I am using c++ (however, I am just learning the basics at this point). If anyone can help point me in the right direction with regard to which opencv library algorithms to use I'd appreciate it. Perhaps a part of a background detection code can be used with minor tweaks? Thanks. |
