I want to somehow increase the contrast if it is the thing to do. What I want is make the edge darker and clearer, so that I can detect it better in binary image. For example this is what I want:
But I made this through picture manager not MATLAB. How can I do this with matlab? If I use imadjust or etc for enhancing contrast, I get this:
which is not what I want. Now these are my questions:
1. How can I use MATLAB to get the second image? I do not know how to use imajust or imcontrast to do so.
2. Is my whole method good or efficient for my final purpose? (clearer edge in binary)?
Thanks so much Steven
