选取两幅图像的对应点后计算出变形函数，图像变形后再将两幅图像镶嵌为同一副图像-Select the two images correspond to point out the deformation function, image deformation and then to two images for the same Vice-image mosaic

this function warp image according to the parameters it takes. it uses interpolation and help in lucas kanade algorithm. have fun
