The dst coordinates refer to the 2 red points on the left, and the 2 blue points on the right of the image, in clockwise order. I would like the distorted image to contain just the piece of paper, and have the five blocks be roughly the same size. However, the warped image turns out to be: Projective transformations. Let's have some more fun with the images and see what else we can achieve. For CylindricalWarper and SphericalWarper it is cylinder and sphere, respectively. I'm trying to perform a complex warp of an image using Dense Optical Flow (I am trying to wap the second image into roughly the same shape as the first image).

The goal of this exercise is to take the 4 corner points of a Pokercard from a laying perspective and warping it flat in front of you. OpenGL 2D Image Warper. Thanks a lot. C++ library. Any help would be nice. If some of them correspond to outliers in the source image, they are set to zero . ... After you have the homography matrix, you need to warp the image with respect to the Homography matrix. The idea is that I want to "stretch" the image such that the 2 red points on the right correspond to the 2 blue points. Guess which one was made using flow and which one was made using zeros mat. im2w = warp_flow(im1gray*255, flowFB) im2w_fake = warp_flow(im1gray*255, np.zeros_like(flowFB)) So, in second case i've just putted matrix full of zeros.
