We now know that to warp a triangle to another triangle we will need to use the affine transform. In OpenCV, warpAffine allows you to apply an affine transform to an image, but not a triangular region inside the image. To overcome this limitation we find a bounding box around the source triangle and crop the …
WebNext, create the 2D-rotation matrix. OpenCV provides the getRotationMatrix2D() function that we discussed above. Finally, apply the affine transformation to the image, using the rotation matrix you created in the previous step. The warpAffine() function in OpenCV does the job. The warpAffine() function applies an affine transformation to the image.
