Finding the maximum points

I have images,where each image has sine wave ,now i want to find the maximum point of each positive peak and find the distance between them,please help

[Thomas]

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?

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.
