Harris 3D: a robust extension of the Harris operator for interest point detection on 3D meshes論文解讀
本文是將參照二維Harris角點檢測改進而來，目的是在三維點雲中檢測出關鍵點。 1、計算Harris算子 爲了計算導數，我們將二次曲面擬合到以下點上變換點的集合。利用最小平方法，我們找到一個拋物線的形式。 我們選擇了一個只有6個項的二次曲面，因爲它代表一個拋物線。也就是說，如果我們需要一個帶有二次項的兩個變量的函數，它是最佳選擇。增加更多的項意味着可以擬合一個更復雜的曲面。然而，更復雜的曲面在域的
