Hello,

I want to know the size of an object from the line profile that I drew over it. Is it possible to extract such information? If possible please help me out.

Hi,

You can use the Freehand object and use the createMask function associated with it to rasterize the marked region into a binary image. Then use the AND operation between the original image and your masked output to get the desired pixel count.

Note that the number of pixel in the image isn't the acutal size of the object and is dependent on the resolution of the image

Hope this helps!
