Hi all,

I have a question to ask. I am doing a project to detect signboard in an image. After detecting the signboard, I need to perform image enhancement techniques on the image. The reason for that is after detecting the signboard, it has some shadows of other images on the signboard.

For example, the signboard is partially covered by something which has some shades on it. Another exmaple is the signboard has the shadow of tree leaves on it.

so, how can I actually remove all this things from the signboard image? I am stuck with this problem and do not know how to proceed on wit this.

Here are the sample images picture: http://img85.imageshack.us/img85/7826/reflectionshadowimages.png

Thanks,
