How to find the best circular fit for an irregular shape and define an average radious for it. The Goal is to define a fix distance on the radious e.g. (0.5 R) from the weighed center and extract the ave od data from those pixels.

Hi Ali Hariri,
For fitting a best circular fit for the data you have you choose from the resources given
1: A suite for minimal bounding objects
2: Circle Fit
3: Fit circles to data points in irregular images
The first two give you a fit if you have the data in coordinates form and the third one utilizes the image data itself.

You can use circularFit(), available at
https://www.mathworks.com/matlabcentral/fileexchange/87584-object-oriented-tools-for-fitting-conics-and-quadrics
Or, you can use regionprops,
reg=regionprops(BW,'WeightedCentroid','PixelList');
averageRadius=mean(vecnorm( reg.WeightedCentroid-reg.PixelList ,2,2));
