WebFirst, this function calculates the corner quality score at every pixel using either Shi-Tomasi or Harris Corner Then this function performs a non-maximum suppression (the local maximums in 3 x 3 neighborhood are retained). After this, all the corners with the quality score less than qualityLevel*maxx,yqualityScore (x,y) are rejected. Web3 Jan 2024 · Method 2: Shi-Tomasi corner detection. Shi and Tomasi came up with a different corner detection algorithm which is mostly similar to the Haris corner detection algorithm in which the only difference will be the kernel value in which we can find only the n strongest corners of the image.
