%% Find Corners in Images % This example shows how to locate corners with the corner function and % adjust your results by refining the maximum number of desired corners. %% % Create a checkerboard image. % Copyright 2015 The MathWorks, Inc. I = checkerboard(40,2,2); %% % Find the corners in the image. C = corner(I); %% % Display the corners when the maximum number of desired corners is the % default setting of 200. subplot(1,2,1); imshow(I); hold on plot(C(:,1), C(:,2), '*', 'Color', 'c') title('Maximum Corners = 200') hold off %% % Display the corners when the maximum number of desired corners is 3. corners_max_specified = corner(I,3); subplot(1,2,2); imshow(I); hold on plot(corners_max_specified(:,1), corners_max_specified(:,2), ... '*', 'Color', 'm') title('Maximum Corners = 3') hold off
