Description: Recognition of visual patterns and characters are independent of position, size, and orientation in the visual field has been the goal of much recent research. The method presented in this paper meets all these condition. An off-line signature matching system which is based on Hu moment invariant method is presented here. Signature matching uses a four - steps process. In first step the scanned or captured color images are initially converted to grey scale. Second step performs normalization and digitization of the original signature. Noise reduction (also called “smoothing” or “noise filtering”) is one of the most important processes in image processing is performed in third step and then moment invariant vectors are obtained in the last step. Signature matching system is implemented using MATLAB and ability of the system can be increased by using additional features in the input data set.

Description: 该目录包含了基于可移植的C语言的数字水印算法的代码。这些代码具有示范
性的意义，且有一定的鲁棒性。
需要安装NetPGM的程序包（用来存取pgm格式图像），然后才能在linux下面编译。
NetPGM是图像文件的输入/输出软件包。可以在网上搜索得到。我们已经对
256灰度级，512×512大小的图像进行了测试。程序编译后的调用格式如下（以encode为例）：
wm_cox_e -s cox.sig -o wm_image.pgm image.pgm
其中，-s表示要添加的水印信号，cox.sig是信号文件。
-o表示输出图像文件名为wm_image.pgm，
image.pgm为输入文件名。
几个辅助程序：
cmp_pgm 计算差分图像，PSNR等
cmp_dct 计算全帧DCT域的差分图像
cmp_dct8x8 计算8×8大小的DCT域差分图像
比如说，为了产生两个PGM图像的差分图像并计算它们的PSNR，命令如下：
cmp_pgm -p -i original.pgm -o diff.pgm watermarked.pgm
产生水印信号：
gen_cox_sig -o cox.sig
程序将产生适合512×512大小，8-bit灰度的pgm图像的水印信号。
水印提取：
wm_cox_d -s cox.sig -i lena.pgm -o cox.wm cox_lena.pgm
请注意，cox的算法需要原始图像做参考来提取水印，压缩后的水印将存储在cox.wm中。-This directory contains the C-based portable digital watermarking algorithm code. The code has a demonstration
Of meaning, and there is a certain degree of robustness.
NetPGM need to install the package (to access the pgm format images), and then to compile in linux below.
NetPGM is the image file input/output package. Can search by. We have already
256 gray level, 512 × 512 size images were tested.
Procedure call format, compiled as follows (in encode an example):
wm_cox_e-s cox.sig-o wm_image.pgm image.pgm
Which,-s that you want to add the watermark signal, cox.sig is the signal file.
-O said output image file name wm_image.pgm,
image.pgm for the input file name.
Several auxiliary programs:
cmp_pgm calculate the difference image, PSNR, etc.
cmp_dct full frame DCT domain calculation of difference image
cmp_dct8x8 calculate the size of 8 × 8 DCT domain differential image
For example, in order to produce two PGM images and calculate their differ

Description: 针对离线签名鉴别可利用的信息少、鉴别难度大的问题，提出了一种基于数学形态学的签名真伪鉴别方法。该方法首先对采集的签名图像进行灰度化、二值化、滤波去噪、取反归一化等预处理，然后利用数学形态学的各种运算，结合不同大小和不同方向的结构元素提取签名中具有明显方向性特征的笔划，最后基于笔划的长短、粗细、间隔等信息对鉴别样本做出判别。实验结果表明，该方法能有效地提高鉴别的正确率，改善鉴别的实时性，对于应用新方法进行离线签名真伪鉴别是一次有益的尝试，具有一定的实用和推广价值。-It is much more complex and difficult for off-line signature identification attributable to the limitation of available information. To solve the problem, a signature identification method based on mathematical morphology is proposed. The signature image is gray-scaled、two-valued、filtered、negated and normalized at the stage of preprocess strokes which possess distinctive directional characteristics are extracted by using mathematical morphology and combining different scales/directions structure element at last judgement are maked for sample in accordance with length、thickness and distance of strokes. Experimental results showed the proposed method can enhance accurate rate effectively, improve real-time performance, which is a try beneficial to apply new methods for off-line signature identification, having the certain promotion application value.
