Image Segmentation Overlapping Objects Same Color

I am trying to sement an image containing a several, overlapping sine waves of the same color. Ultimately I am trying to do two things: (1) Determine how many sine waves there are in an image, and (2) Extract the data seperately for each so that I can perform a curve fit on each wave seperately. Currently, I am able to use color thresholding and active contouring to pull out ALL of the data in a particular image, but I can't separate the data into individual sine waves.

Hi Alex,

I understand from your question that you want the sine wave images to be available separately. Since the sine waves are overlapped, may be you can proceed with a different approach of watershed segmentation. Refer to the below documentation on the same:

Below thread explains how to segment the color image using active contours

The below discussions on the similar lines where the user wants to save the segmented region separately as an image:
