Click a point in n*m grid and recognize the cell edge around it

Hello
I have a X-ray image. There is a n*m grid in the image (It has n*m cells). User may click on the image and I want to get the cell edges (a stretched rectangle) around the point.

The difficuilty here is there might be some noises on the image so I cannot simply judge the cell edge by checking rgb value. For example: 1, In the cell, the left part background may be blacker than the right one. 2, There might be some pixels in the image, they are even blacker than the cell edges.

Thanks
