Matlab implementation by Harrison Wang. a warping like in the image below using an RGB image. The randomAffine2d (Image Processing Toolbox) function creates a randomized 2-D affine transformation from a combination of rotation, translation, scale (resizing), reflection, and shear. Learn more about warping Image Processing Toolbox IMAGE PROCESSING and warping. The transformed image is scaled more in the vertical direction than in the horizontal direction, as expected since Sy is larger than Sx. Cite As Masayuki Tanaka (2020). Applying a geometric transformation to an image is a key step in many image processing applications like image registration. collapse all in page. hanane78.
