%% Find Intersection Points Between a Line and Image Border % %% % Load and display an image. I = imread('rice.png'); figure; imshow(I); hold on; %% % Define a line with the equation, 2 * x + y - 300 = 0. aLine = [2,1,-300]; %% % Compute the intersection points of the line and the image border. points = lineToBorderPoints(aLine,size(I)) line(points([1,3]),points([2,4]));
