Question

(MATLAB example)Write a function that generates an image (a matrix) that contains a circular object with a value of 1 and
0 elsewhere when image size, matrix size, circle center and circle radius are given:
function myImage = circle(imageSize, matrixSize, center, radius);

Answer 1

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

function myImage = Circle(imagesize,matrixsize,center,radius)
Orig = ones(imagesize,imagesize);
imshow(Orig);

[columnsInImage rowsInImage] = meshgrid(1:imagesize, 1:imagesize);
% Next create the circle in the image.
circlePixels = (rowsInImage - center).^2 + (columnsInImage - center).^2 <= radius.^2;
image(circlePixels);
colormap([0 0 0; 1 1 1]);
title('Binary image of a circle');
end
