JSTEG
Jsteg隐写算法[23][24]由D. Upham提出,该算法将秘密信息嵌入在量化后的DCT系数的LSB上,但值为-1、0、+1的DCT系数例外。提取秘密信息时,也只是将隐藏信息的图像中不等于-1、0、+1的量化DCT系数的LSB取出即可(steganography of jsteg)

shadow-removal
该代码用于在视觉智能监控/视频监控/视觉监控/视频智能监控中,消除阴影。阴影消除对视频监控具有重要的意义,能够有效地降低阴影对目标检测的影响,减小误检率和漏检率,提高对目标的识别效率以及监控系统的稳定性和可靠性。(This code is used to remove shadow in visual intelligent surveillance/video surveillance/visual surveillance/video intelligent surveillance. Shadow removal plays a important role in video surveillance. It reduce the affection of shadow in object detection, decrease false detection rate and missing rate, and improve the stability and reliability of surveillance system.)

kl
说明: kl变换. KL变换的流程如下:
(1)获取多幅图像的统计特性:图像之间的协方差
(2)获取协方差的特征值和特征向量,从而获取正交核:特征矩阵
(3)图像对应象素点对各个特征向量进行投影运算。(kl transformation)
