一种改进的Harris角点检测算法An improved Harris corner detection algorithm 摘要 角点是图像的重要特征点,图像的角点包含了图像的很多信息,与此同时, 角点的个数要远远少于像素点的个数,通过对角点的计算和分析,能让我们掌握 图像中物体的形状。由于角点具有旋转不变性,它集中了图像上很多的重要信息。 在没有丢失...
角点检测程序Harris Corner Detector是一种用于在图像中检测角点的算法。它通过计算图像的梯度向量,并找到梯度向量的模长和方向,从而确定角点的位置。该程序在MFC(Microsoft Foundation Class)下实现,可以有效地检测出图像中的角点。 角点检测程序的主要步骤如下: 1. 读取图像并将其转换为灰度图像。 2. 对灰度图像进行...
