I needed to run some parts of the code in GPU using cupy instead of numpy. So, I only made comment out for this line # import numpy as np and used this line ins
How can I calculate distance from camera to a point on a ground plane from an image? I have the intrinsic parameters of the camera and the position (height, p
I'm trying to use OpenCV.js in web workers in Angular. My project needs to conduct multiple graphic computings at the same time, which would take long time. But
In the image below, I am using OpenCV harris corner detector to detect only the corners for the squares (and the smaller squares within the outer squares). Howe
How can I paste a smaller image into the center of another image? Both images have the same height, but the smaller one has a width that is always smaller. The
