how to divide the image into equal sectors from central point.

I want to do following task.

• # 1. Divide the image into equal sectors from a central point of the image
• # 2. count the number of pixel in each sectorThis is code for find central point

C= imread('LED.png);
A=rbg2gray(C);
binaryImage= A>250; 
labeledImage = bwlabel(binaryImage);
measurements = regionprops(labeledImage, 'Centroid', 'BoundingBox');
xCentroid = measurements.Centroid(1);
yCentroid = measurements.Centroid(2);
boundingBox = measurements.BoundingBox;
