The additional image extent in each is added on one side of the image, in the direction that the translation vector points. B = warp(w,A) applies the geometrical transformation defined by image warper w to input image A and returns the warped image in B. Again the transformation is correct (tested using FMRIB's-FLIRT registration software). Image warping is a transformation that is applied to the domain of an image, which modifies the geometrical properties of the image itself. Forward 2-D translation transformation, specified as a 3-by-3 numeric matrix. When the center of a pixel in the output image does not map to the center of a pixel in the input image, imwarp interpolates within the input image to calculate the output pixel value. Translation .
