I have a modified R-G-NIR camera able to record video and I was wondering if there is any software (preferabily open source) to edit the video allowing for (1) R-G-NIR channel splitting and (2) computation between channels to compute NDVI.
The idea is creating a NDVI video, no extracting the frames to have NDVI still shots.
Thanks in advance!!
Hi Alex, I use OpenCV + Numpy in Python to do similar things. It should work with any standard video format.
You can also create image mosaics directly from video using the free Image Composite Editor and then adjust as a mosaic image afterwards. We apply our calibration coefficients and corrections by band in FIJI.
Many thanks, Shwan!
We did some tests using Matlab, as well. It is certainly quite easy: opening the video file, creating a loop to extract each frame + extracting the channels + computing the NDVI and, finally, creating the new video with the modified frames.
Thanks both!
