Dear Friends,

I have a problem which might not be related to this topic. However, I want to compare my velocity contour with a paper. Now I have an image file of the contour of the paper and I want to have the values of the velocity in some points to compare it with my contour. some says that Matlab can extract data values from images; however, I couldnt find the solution. does anyone knows what I should do?

Best regards
