Accepted answer

If you have the image processing toolbox, define your axes, x and y, them display your image with say imagesc(x,y,img); Then,

Use imdistline(gca) to graphically measure the distance between any 2 points of interest to you.

If I understand you right, you want to extract the numerical value of the peak of sine wave, and the distance between the peaks from an image.. Can you please post the image as well?
