colorhistgram

通过dct的8*8块的变换量化操作结合水印生成水印图像，其中包含几种常见的攻击测试。(The program generates watermark image through DCT transform.)

实时统计监控视频下路人人数，采用python(This is a demo made for tracking pedestrian)

实现图像文件（如bmp等）的读取、显示、真彩图转换成灰度图、灰度图转化为二值图及绘制图像直方图功能。(Achieve an image file (such as bmp, etc.) to read, display, true color conversion to grayscale, converted to grayscale and binary image histogram function to draw the image.)

相关法求旋转平移图像的旋转角度 转极坐标方法2 另一法见本人另一程序包(Correlation registration method for rotation angle (polar coordinates method 2))

信息检索和自然语言处理中经常会使用这些参数:准确率（Precision）、召回率（Recall）以及综合评价指标（F1-Measure ） (These parameters are often used in information retri and natural language processing (Precision), recall rate (Recall), and comprehensive uation index (F1-Measure). )

用斯托克斯矢量法，计算偏振度图像和偏振角图像，方便进一步处理。(Degree of polarization and angle of polarization calculating)

matlab模拟产生马鞍形光学条纹图，通过求取其条纹方向，二值化得到其巨齿包裹图，中心线图。这些对于激光散斑（ESPI），雷达干涉（INSAR）图像的去包裹有重要的指导意义。()
