Description: 1. 视频数据读取，读取相邻两帧中的人眼最敏感的亮度数据。 2. 用后一帧的亮度矩阵减去前一帧亮度矩阵，计算出两帧的帧差。 3. 迭代计算出帧差中的噪声的均值和标准差。 4. 根据均值和标准差滤除噪声，得到变化区域。 5. 用数学形态学运算得到对象的最终模板。-1. Video data is read, read two adjacent eyes of the brightness of the most sensitive data. 2. After a brightness of the matrix before a less brightness matrix, calculated two frames worse. 3. Iterative Frame calculated the noise mean and the standard deviation. 4. According to the mean and standard deviation of filtering noise, changes to be regional. 5. Operators using mathematical morphology to be the ultimate target template. Platform: |

Description: This project deals with the tracking and following of single object in a sequence of frames
and the velocity of the object is determined. Algorithms are developed for improving
the image quality, segmentation, feature extraction and for deterring the velocity. The
developed algorithms are implemented and evaluated on TMS320C6416T DSP Starter
Kit (DSK). Segmentation is performed to detect the object after reducing the noise from
that scene. The object is tracked by plotting a rectangular bounding box around it in
each frame. The velocity of the object is determined by calculating the distance that the
object moved in a sequence of frames with respect to the frame rate that the video is
recorded. The algorithms developed can also be used for other applications (real time,
object classi cation, etc.). Platform: |

Description: 本文提出一种在原始视频DCT(离散余弦变换)与SVD(奇异值分解)域自适应嵌入水印的算法。算法首先将视频流分割成一个个场景,场景中的视频图像被变换到DCT-SVD域中,水印量化嵌入在最大奇异上,实现了水印盲检测。同时实验证明该算法在满足透明性要求下也满足一定的鲁棒性要求,能够抵抗低通滤波、中值滤波、椒盐噪声、高斯噪声、H.264压缩攻击以及统计攻击和帧剪切等攻击。-This paper presents an original video in the DCT (Discrete Cosine Transform) and SVD (singular value decomposition) algorithm for adaptive watermark embedding. Firstly, a video stream is divided into scenes, scenes of the video image is converted to the DCT-SVD domain, the watermark embedded in the largest singular quantification, the realization of the watermark signal. Furthermore, the experiments show that the algorithm meet the transparency requirements are met under certain robustness requirements, can resist the low-pass filtering, median filtering, salt and pepper noise, Gaussian noise, H.264 compression attacks and attacks and frame shear statistics attack.

Description: 1.基本内容
本设计目标在于利用Matlab强大的图像处理能力和实用便捷的编程方法，通过处理包含人脸的视频帧系列图像，灰度积分投影技术的眼睛定位方法，进而利用perclos计数，计算眨眼率，从而得到比较准确的疲劳状况。
2.具体要求
本设计基于灰度积分投影技术的眼睛定位方法，再结合perclos技术。首先通过图像预处理技术得到灰度分配较为均匀的图像,然后分别利用水平和垂直灰度积分投影曲线结合人脸的结构特征找到眼睛的位置坐标,实现了准确的眼睛定位,通过perclos技术技术眨眼率，根据先验值得到是否疲劳。(The goal of this design is to use MATLAB's powerful image processing ability and practical and convenient programming method, through processing the video frame series images including the face, the eye location method of gray integration projection technology, and then use PERCLOS count to calculate the blink rate, so as to get a more accurate fatigue condition.)
