k=imread('cell.bmp');
BW1=im2bw(k);
BW2=imcomplement(BW1);
% Apply condition calculate the pixels in certain boundary area (objects)
% Once you find white pixels, sum all upto certain boundary (Hint from given image)
% following is the code for all objects
nWhite_pixels=sum(BW2(:));
[rows columns depth]=size(BW2);
percentage_tot_area=((nWhite_pixels)/(rows*columns))*100;
fprintf('#The Percentage covered by all object is %f',percentage_tot_area);
disp('%');
