Image Reconstruction (ART)

针对图像秘密共享前需要像素置乱的问题，基于(t, n)门限多重秘密共享思想，提出一种免置乱的图像秘密共享方案，以第n+1人的秘密份额作为因子参与秘密分割与重构，加大相邻像素之间的差距(Based on (t, n) threshold multiple secret sharing ideas, and put forward a kind of scrambling image from secret sharing scheme to n+ 1 people share the secret as factors involved in secret segmentation and reconstruction, increase the gap between adjacent pixels)

sift算法的完整matlab程序,本人测试过，很好，稍加修改即可！(complete sift algorithm matlab program, I tested, well, a few minor changes!)

图像增强利用直方图均衡来达到增强图像对比度的目的，从而来实现增强图像的效果(Image enhancement using histogram equalization to achieve the purpose of enhancing image contrast and thus to realize the effect of enhanced images)

比较反滤波和维纳滤波对一幅图像复原的效果。从两方面出发，一是对运动模糊和均值模糊复原的能力，二是抗噪能力，各种情况分别都进行了对比(Comparison of inverse filtering and Wiener filtering on an image restoration results. Proceed in two ways, first on the motion blur and the mean fuzzy recovery capability and noise immunity, all cases are compared separately)

利用PCA检测图像的复制粘贴区域。检测效果良好。(PCA was used to test digital image s copy and paste area.)

说明：  傅里叶分解计算基波有效值相位角和各次谐波的有效值和相位角(Fourier decomposition of computing fundamental RMS phase angle and harmonic RMS and phase angle)

matlab代码实现meanshift图像分割算法，有较好的效果(matlab code meanshift realize image segmentation algorithm has better results)

说明：  对灰度图象进行正交变换,并进行滤波,产生平滑图象(Gray-scale images of the orthogonal transformation, and filtering to produce a smooth image)

Susan算法，用于角点检测。很先进的方法，国内有人改进过，这是原来的方法。(Susan algorithm for corner detection. The most advanced methods, there are those who improved, this is the original method.)
