Replace negatives by zero. Use warpPerspective to translate X,Y,Z. The only problem is that in case of occlusions due to a something closer than Z, I don't think I'd get a smooth new depth map. If there was a small object close by, it might make the depth … Web19 de jan. de 2024 · Find difference between the 2 images. Convert the image to grayscale.
