Edge detection in an image

Hi!

I would like to measure the water table in each point of the attached image but i do not know what is the best way to proceed. I have tried fuzzy logic and edge detector Canny algorithm.

Thank you all beforehand.

What does "water table" menas here?

[Sergio Lozano]

It is the surface of the wave, its height

Hi,

Use the Image Segmenter App, to extract the region of interest ( region between the ground and the water surface).

• Draw the ROI using the Assisted Freehand and generate the binary image
• Export the binary image to the MATLAB Workspace and use the regionprops() function to extract the required properties from the binary image.

Please find the attached binary mask for 'wave.png' image file.

Refer the link for more information on different function used to calculate image properties.
