I need your valuable suggestion. I am working on removing moving shadow of video. as an example i am attaching one of the frame of my working video. Please refer the attached image and suggest me is it possible to remove this long shadow? Thank you

It is possible that you may not be able remove complete shadow out of the image as it is very dense shadow, I would suggest, to try with the method in link (It may work).

For removing the shadow in video, convert video into frames and then remove shadow from each image(Frame). After removing shadow, combine all frames to form the video.
