abnormal_detection
- 由c++和opencv，利用运动人体外接矩形的长宽比来检测人体异常行为的发货谁能，如摔倒和下蹲- Using the human body to connect the rectangular aspect ratio to detect abnormal behavior of the human body who can ship, such as fall and squatting
Light_Flow
- 利用opencv本身自带Lucas_Kanade的函数来表示运动目标的光流轨迹-Using opencv itself comes with Lucas_Kanade function to represent the moving target optical flow trajectory
opencv-Polargeometry
- 依据极线几何原理，用opencv实现对两幅图像检测特征点后计算基本矩阵。在其中任意一幅图像中选点，在另一幅图中显示极点和极线。-Based on the principles of epipolar geometry, with opencv after two images to detect feature points to calculate the basic matrix. In either an image point, poles and lines displayed in
Image-Corrosion
- 腐蚀是图像形态学的两个基本操作之一，另外一个是膨胀(Dilate)。二值图像上的腐蚀是腐蚀最典型的运用，但是腐蚀操作同样可以运用于灰度图像。二值图像腐蚀操作最基本的效果是腐蚀图像中前景色区域的边缘。使得前景图像区域变小，前景图像内部的背景区域被放大。-Corrosion is one of the two basic operation of the image morphology, and the other one is the expansion (Dilate). Corrosion
Histogram-equalization
- 如果一副图像的像素占有很多的灰度级而且分布均匀，那么这样的图像往往有高对比度和多变的灰度色调。直方图均衡化就是一种能仅靠输入图像直方图信息自动达到这种效果的变换函数。它的基本思想是对图像中像素个数多的灰度级进行展宽，而对图像中像素个数少的灰度进行压缩，从而扩展像原取值的动态范围，提高了对比度和灰度色调的变化，使图像更加清晰。-If an image pixel occupies a lot of gray level and evenly distributed, so such images
MeanShift
- MeanShift算法是一种无参概率密度估计法，算法利用像素特征点概率密度函数的梯度推导而得， MeanShift算法通过迭代运算收敛于概率密度函数的局部最大值，实现目标定位和跟踪，也能对可变形状目标实时跟踪，对目标的变形，旋转等运动也有较强的鲁棒性。MeanShift算法是一种自动迭代跟踪算法，由 MeanShift补偿向量不断沿着密度函数的梯度方向移动。在一定条件下，MeanShift算法能收敛到局部最优点，从而实现对运动体准确地定位。-MeanShift algorithm is a no
