I'm building a project based on the example stated in this link : http://www.mathworks.com/help/vision/gs/object-detection-and-tracking.html#btt5qyu , "Detect Objects in a Cluttered Scene Using Point Feature Matching.
After detecting the needed part of the target image , a rectangular polygon is plotted around it, i need to crop the part of the target image enclosed by this polygon.
i tried the following method.Icropped=imcrop(II,newBoxpolygon); This snap of the code if true boxPolygon = [1, 1;... % top-left size(boxImage, 2), 1;... % top-right size(boxImage, 2), size(boxImage, 1);... % bottom-right 1, size(boxImage, 1);... % bottom-left 1, 1]; % top-left again to close the polygon
% Transform the polygon into the coordinate system of the target image. The transformed polygon indicates the location of the object in the scene.
newBoxPolygon = transformPointsForward(tform, boxPolygon);%Display the detected object.
figure();imshow(sceneImage);hold on;line(newBoxPolygon(:, 1), newBoxPolygon(:, 2), 'Color', 'R');title('Detected Box');Icropped=imcrop(II,newBoxPolygon);imshow(Icropped);end
and also i tried Icropped=imcrop(II,line); (Note:II is my target image) in both cases im getting an error i dont know whats the problem can any one tell me whats the problem with the method im using. this is the error im getting " [x,y,a,cm,spatial_rect,h_image,placement_cancelled] = parseInputs(varargin{:}); "
Thanks in return.
