Use MATLAB in python for dual-target determination Environmental preparation Calibration image preparation Code building at last Recently, I discovered a problem when performing dual-object calibration on the camera: the results calibrated by python-opencv are unstable and not as stable and convenient as matlab calibration. However, matlab’s image processing is not as convenient as python’s, and […]

POJ 2429 Miller-rabin prime number determination + pollard-rho prime factorization + Essie method
The topic cannot be said to be difficult, but a lot of mathematical knowledge (Fermat’s little theorem, miller-radin, pollard-rho) is used, as well as some algorithmic knowledge DFS, which is divided by turns. I am also very good. I spent a weekend on this topic, but I wrote a lot of notes and spent a […]
