The randomAffine2d (Image Processing Toolbox) function creates a randomized 2-D affine transformation from a combination of rotation, translation, scale (resizing), reflection, and shear. Applying a geometric transformation to an image is a key step in many image processing applications like image registration. The algorithm accepts a source image, a destination image, then click n feature points on source an bonjour tout le monde et bonne week end je veux savoir c'est koi une image warping parceque j'ai une fonction qui calculer cette image mais j'arrive pas a le comprendre est ce que si possible de m'expliquer ca veux dire koi cette fonction Merci. I have to do it by following pseudo code given to me by my professor and I'm making very little progress. 6 Downloads.
