各种低秩约束矩阵填充方法

完成图片的哈哈镜效果，如三角形，圆形，波浪形，弯曲等等(change the picture to any shape you want)

说明：  基于JPEG的图像压缩，觉得可用，同学的毕业设计作品(Based on the JPEG image compression that can be used, students design the graduation)

图像处理算法质量评估，图像结构相似度（ssim)评价的matlab实现，并附带原始论文pdf(This is an implementation of the algorithm for calculating the Structural SIMilarity (SSIM) index between two images. Please refer to the following paper: Z. Wang, A. C. Bovik, H. R. Sheikh, and E. P. Simoncelli, "Image quality assessment: From error measurement to structural similarity" IEEE Transactios on Image Processing, vol. 13, no. 1, Jan. 2004.)

这是用于人脸识别和人脸定位的主动形状模型（asm）matlab工具箱。推荐(This for face recognition and facial shape positioning initiative model (asm2) Matlab toolbox. Suggest)

说明：  使用matlab做分水岭算法，分水岭算法是图像分割中常用的算法，算法的理论依据待考究，适用场景可供分析讨论。(watershed algorithm using matlab)

对matlab中的GUI界面设计进行讲解并附有案例，例如如何进行界面菜单和控件设计，不同GUI之前函数传递，并讲解了如何调用自身函数(Matlab GUI interface design to explain the attached case, for example, how to interface menus and controls design, the different GUI function is passed before, and explain the how to call its own function)

一种基于孔径编码的图像复原方法，效果非常好，不过缺陷是需要知道PSF等先验知识(Based on coded aperture image restoration method, the effect is very good, but the deficiencies need to know a priori knowledge of PSF, etc.)

说明：  Create hex map settigns

求灰度图像的梯度特征向量，以便用于目标检测(The grad feature of gray image can be achieved by the code.)

用OSTU和KSW实现多阈值图像分割，matlab代码(Image Segmentation Using OSTU and KSW)
