目前生成全息图主要有傅里叶和菲涅尔变换，此代码为利用菲涅尔变换将二维图片生成菲涅尔全息图，以达到图像加密的功能。(The current generated hologram mainly Fu Liye and Finel transform, the code for the use of Finel transform two-dimensional images generated Finel hologram, in order to achieve the function of image encryption.)

The QTimer class provides repetitive and single-shot timers for Linux.

特征提取: 提取了图像中各个标记区域的纹理特征及形状特征,标注详细(King Lek qiong 取: Joan 取了 Minghao Shilu rude plugging 各个标记区 的 理 Canton King Lek Lek 及 near Durian King, 标 downtown Circle Jiu)

基于块的OMP算法，相对传统的OMP算法速度很快！(Batch-based OMP algorithm,execution quickly than the comman OMP algorithm.)

数字音频水印程序，有嵌入和提取及攻击处理(Digital audio watermarking procedures, embedding and extracting and aggressive treatment.)

calibration摄像机镜头的校正程序(calibration Calibration camera lens calibration procedure)

二维Renyi熵图像分割源代码（原创） 参考文献见源代码。(source code for two-dimensional Renyi entropy thresholding algorithm)

说明：  一种新的图像清晰度评价函数,该函数对经典采用八方向模板Sobel边缘检测算子来检测梯度值(A new image definition evaluation function, which uses eight direction template Sobel edge detection operator to detect gradient value)

经典的meanshift跟踪算法，很好的跟踪框架，注释详细。(Meanshift classical tracking algorithm, a good tracking framework, detailed notes.)

说明：  基于暗通道先验的但图像去雾,暗通道先验就是基于这样一个假设：在绝大多数非天空的局部区域里，某一些像素总会有至少一个颜色通道具有很低的值。(Single Image Haze Removal Using Dark Channel Prior.)
