Hello, good afternoon.
I need help with image processing using the OpenCV library. Basically, I need to take a satellite image and apply the NDVI (vegetation index by normalized difference). Its calculation is simple:
NDVI = (NIR - RED) / (NIR + RED)
Where Near Infrared (NIR) is the image of band 5 that is infrared and RED is the image of band 4, which is red.
But after applying this formula I have no results other than a black background image. If anyone can help, thanks.
