Hello Everyone,
I am applying shearing on an image which is 512x512 pixels. When i am executing the code I am getting bigger images like 615x512 and in y-axis 512x615. Shear should lie in the 512x512 frame, but both output images are different in scale. Please tell me what am I doing wrong here?
Thanks in advance :-)
subplot(3, 3, 3);
tformImage = affine2d([1 .2 0; 0 1 0; 0 0 1]); %shear x-axis
shear = imwarp(Image, tformImage);
disp(size(shear));
imshow(shear);
title('Shear Attack x-axis','FontSize', fontSize);
set(gcf, 'Position', get(0,'Screensize'));
axis off

You should use an imref2d object to specify the output view, using the syntax,
B= imwarp(A,RA,tform,'OutputView',RA)
