WebJun 14, 2024 · This is another corner detection algorithm. It works similar to Harris Corner detection. The only difference here is the computation of the value of R. This algorithm also allows us to find the best n corners in an image. Let’s see the Python implementation. This is the output of the Shi-Tomasi algorithm. Here the top 20 corners are detected. WebIf you want to implement SIFT properly, optimized C++ code (including SIMD optimizations or even GPU help) is the way to go.
