what is the data format of static image? is it 4 channel or 3?
i have to try with static image to see if its format differs from webcam
as far as i know getImageData should always return RGBA format. so probably the problem that u didnt draw image to canvas before trying to getImageData

Thank you for the reply.
The problem was not the RGBA format, but rather, it was the image not drawn to the canvas before trying to getImageData.
jsfeat.imgproc.grayscale worked fine after making a button to process the image.
