说明：  掌纹roi提取 掌纹图像处理 图像分割(Extraction of palmprint roi)

C++ code implementing the estimation of errors-in-variables models under point dependent noise. It includes examples for linear, ellipse, fundamental matrix and trifocal tensor estimation. The theory is described in A general method for errors-in-variables problems in computer vision(err)

图像分割程序，采用水平集演化的思想，实现偏微分方程中的GAC模型。Image segment source code(GAC model),which adopt the idea of level set evolving.(Image segmentation procedures, the use of level set evolution of thought, the realization of partial differential equations of the GAC model. Image segment source code (GAC model), which adopt the idea of level set evolving.)

提出了一种基于纠错编码的DCT域数字水印算法,该算法在检测时不需要原始图像,实现了盲检。并且对水印图像进行了利用超混沌置乱处理,提高了安全性能和抗攻击能力。纠错编码的引入使水印抗攻击能力明显增强。 (DCT digital watermarking algorithm based on error correction coding, the algorithm detected without the original image, blind. And watermark image of the the hyperchaotic scrambling process, improve the safety performance and anti-attack capability. The introduction of error correction coding watermark anti-attack capability significantly enhanced.)

快速检测复制粘贴图片，用于检测图像是否为复制粘贴伪造的(This program detect the copy-move forgery in images as described)

图像孔洞/裂缝的填充算法。根据图像的同态性，采用最邻近插值的思想。(Image holes/cracks in the fill algorithm. According to the image of the same state, using the nearest interpolation ideas.)

这里的图像增强包括灰度修正、平滑、滤波、锐化等，是图像处理的基本操作，本代码调试通过(Here, including gray-level correction image enhancement, smoothing, filtering, sharpening, etc., is the basic image processing operations, the code debugging by)

Speedy GA Graphical analysis

等效视数表示遥感图像滤波后的滤波效果，这个程序可以计算等效视数。(Equivalent number of said filtering effect, this program can calculate the equivalent number of remote sensing images filtered.)

hough和randon函数求图像中圆，对于水中气泡检测效果很不错(Circle detection based on random Hough transform)
