Question

Exercise 3: (1) Research Matlab commands, affine2d, imwarp, imrotate, imtranslate, imresize. (2) Read the image, cameraman.tif. Scale the image in the following different ways. (a) 2 times of x, 2 times of y. Here x is the horizontal direction (columns), y is the vertical direction (rows); (b) 2 times of x, 0.5 times of y: (c) 0.5 times of x. 1 time of y. (3) Read the image, cameraman.tif. Rotate the image in 60°, -60°. Compare different interpolation methods. (4) Read the image, cameraman.tif. Translate the image to [10 20], [-20 50], [20, -30]. (5) Read the image, cameraman.tif. Choose your own values to create vertical and horizontal shear effect.
