- 图像中的角点包含大量的信息，在计算机视觉中扮演重要角色，在许多应用中角点用作特征点，例如图像配准、运动目标跟踪等。鉴于此，学者们提出很多角点检测方法。例如Hans EMoravec在1977年提出的Movavec算法，Chris Harris和Mike Stephens于1988年提出的Harris算法，以及MirosavTrai．kovic和MarkHedley提出的Trajkovic算法等“卅。角点检测的另一个途径是计算轮廓的曲率函数，因为角点是曲率函数的最大值，因此很容易通过阈值的方法检测

- 图像去噪理论基础图像视频去噪的最终目的是改善给定的图像，解决实际图像由于噪声干扰而导致图像质量下降的问题。通过去噪技术可以有效地提高图像质量，增大信噪比，更好的体现原来图像所携带的信息，作为一种重要的预处理手段，人们对图像去噪算法进行了广泛的研究。在现有的去噪算法中，有的去噪算法在低维信号图像处理中取得较好的效果，却不适用于高维信号图像处理；或者去噪效果较好，却丢失部分图像边缘信息，或者致力于研究检测图像边缘信息，保留图像细节。-Image denoising theory based imag
