Web8 de jan. de 2013 · Armed with both sets of points, we calculate the Affine Transform by using OpenCV function cv::getAffineTransform : Mat warp_mat = getAffineTransform ( srcTri, dstTri ); We get a matrix as an output (in this case warp_mat) We then apply the Affine Transform just found to the src image. Web4 de mar. de 2024 · Plotting the image after applying the transformation clearly shows that the original image has been rotated 90 degrees clockwise and scaled up 2X. However, the result is now obviously diminished as you can easily see discontinuity in the pixel intensities. To understand the reason for this I will again utilize a simple grid plot for demonstration. shr tool
