1. A computer-implemented method for transforming feature regions included in a sequence of images, the method comprising: receiving a first sequence of images having a first image format; receiving input specifying a second image format; determining feature regions of the first sequence of images; computing a warp of the first sequence of images from the first image format to the second image format, wherein at least one feature region of the first sequence of images is transformed based on an affine transformation; and generating a second sequence of images having the second image format, wherein the second sequence of images includes the at least one feature region transformed based on the affine transformation.
