WebMar 14, 2024 · Here's an example of how you can implement panoramic stitching using the optical flow tracing principle in Python: Start by importing the necessary libraries, such as OpenCV, Numpy, and Matplotlib. import cv2 import numpy as np import matplotlib.pyplot as plt. Load the images that you want to stitch into a list. WebDec 10, 2024 · Lucas-Kanade method computes optical flow for a sparse feature set (in our example, corners detected using Shi-Tomasi algorithm). OpenCV provides another algorithm to find the dense optical flow. It computes the optical flow for all the points in the frame.
