canny
- Canny 的目标是找到一个最优的边缘检测算法,最优边缘检测的含义是: 好的检测- 算法能够尽可能多地标识出图像中的实际边缘。 好的定位- 标识出的边缘要尽可能与实际图像中的实际边缘尽可能接近。 最小响应- 图像中的边缘只能标识一次,并且可能存在的图像噪声不应标识为边缘。-Canny goal is to find an optimal edge detection algorithm, the optimal edge detection means: Good test- a
harris
- 该算法是基于像素领域包含若干元素的近似圆形模板,对每个像素基于该模板领域的图像灰度计算角点响应函数(CRF)的数值,如果大于某阈值且为局部极大值,则认为该点为角点。角点的精度与圆形模板大小无关,圆形模板越大,检测的角点数越多,则计算量也越大,本文圆形模板包含37个元素,该近似圆形模板-The algorithm is based on pixel art consists of several elements approximation circular template for each p
Background-difference-method
- 背景差分法是采用图像序列中的当前帧和背景参考模型比较来检测运动物体的一种方法,其性能依赖于所使用的背景建模技术。背景差分法检测运动目标速度快,检测准确,易于实现,其关键是背景图像的获取。在实际应用中,静止背景是不易直接获得的,同时,由于背景图像的动态变化,需要通过视频序列的帧间信息来估计和恢复背景,即背景重建,所以要选择性的更新背景。-Background difference method is the use of images in the sequence of the current
Optical-flow
- 光流是一种简单实用的图像运动的表达方式,通常定义为一个图像序列中的图像亮度模式的表观运动,即空间物体表面上的点的运动速度在视觉传感器的成像平面上的表达。-Optical Flow is a simple and practical expression of motion pictures, generally defined as the apparent motion a sequence of images in an image brightness mode, ie velocity
Inter-frame-difference-method
- 帧间差分法是一种通过对视频图像序列中相邻两帧作差分运算来获得运动目标轮廓的方法,它可以很好地适用于存在多个运动目标和摄像机移动的情况。 -Frame difference method is a sequence of video images through the adjacent two for differential operation to obtain moving object contour method, which can be well applied to the
meanshift
- 一般是指一个迭代的步骤,即先算出当前点的偏移均值,然后以此为新的起始点,继续移动,直到满足一定的结束条件。-Generally refers to an iterative step, which is to offset the calculated mean of the current point, and then as a new starting point, continue to move until the end of the meet certain conditions.
