Hi, I have some problem to my diesel spray and combustion image. I want to change the background of the image to black.because the quality of the image is bad, so I don't know how to mask the image. Thanks a lot.

What part of the image do you want to make black? It looks like it already is entirely black.

Please create an image that you'd want as the output. And what do you want to do assuming you can make it a black background? Measure area fraction or blob size distribution or something?

Thank you very much for your reply. The output which i want have been marked as Yellow. Firstly, I think I have to find the boundary of the edge, and then cut the background.
