function i = MidpointCircleMod(i, radius, xc, yc, BorderColor, FillColor, filled)
Draw a circle in a matrix using the integer midpoint circle algorithm. Does not miss or repeat pixels
This modified version will draw circle on image by changing pixel values by given
border and fill color value. Border and fill color maybe a RGB array on
a value of uint8 class.
Example use:
%1-) Drawing on a RGB image
im = imread('ftGradient-1.jpg');
im = MidpointCircleMod(im, 75, 120, 200, [255 128 64], [128 255 255], 1);
figure, imshow(im);

%2-) Drawing on a Gray image
im = imread('ftGradient-1.jpg');
im = rgb2gray(im);
im = MidpointCircleMod(im, 75, 120, 200, [255 128 64], [255 255 255], 1);
figure, imshow(im);
