数字图像处理中的平滑和锐化（边缘检测）。包括1、添加椒盐、高斯噪声。2对噪声污染的图像分别使用邻域平均法、中值滤波法、K邻近平均法进行平滑。3对一幅图像利用Roberts梯度法、Sobel算子和拉普拉斯算子进行锐化，并比较结果。附处理源图像和处理结果截图。 -Digital image processing smoothing and sharpening (edge detection). Including 1, add salt and pepper, Gaussian noise.

Laws纹理策度是用来进行纹理分割的程序,这种方法很有用.-Laws degree texture strategy are used for texture segmentation procedure, this method useful.

根据指纹的固有规律，提出了一套较完整的指纹图像预处理和特征提取算法。改进了指纹脊线频率求取算法和二值图像去孔噪声 算法，并提出了一种新的滤除指纹伪特征点的方法。通过对上百幅不同质量的指纹图像进行测试，获得了较好的效果。 关键词：指纹；预处理；特征提取-According to the inherent laws of fingerprints, a set of more complete fingerprint image pre-processing and feature extr

用matlab写的一个模仿抛物线动作的动画。可以自己设定加速度、启示位置等数值。-The laws for rotation are probably wrong (I made them up actually), but that s not what this file is about. Shown here is a very simple code that creates a nice animation, which can be quickly edited to suit a
