Hello to all, I would like to ask for your help to find a solution to the following problem I have. The problem is that at the time of using the command ImageCompose the sign that stands on the top of the image has a white background and that is what I would like to delete, that only appear green letters on the image, and try to use Background-> None, but I failed to erase the white background, I hope that someone can guide me to solve my problem , thanks in advance.

Here is a picture of the problem that I have.
