The vehicle shadow's detection and elimination work basically for extracting and tracking the vehicle characteristics, and it also plays a very important role in highway video surveillance and incident detection, affecting the post-processing of video image directly, such as vehicle tracking and speed measurement. On study of Kimmel variational and multi-scale Retinex algorithm to eliminate the vehicle...
Compared with traditional image smoothing method, partial differential equations -based image smoothing method is better in preserving image features while suppressing image noise. The PDE-based image denoising smoothing algorithm and an improved algorithm based on it are discussed in the paper. A good result is achieved in the experiment of identifying flaws on precise optical componentspsila surface...
A novel algorithm of three-layer probability model based on synchronous detection lines is proposed to solve the problems of background updating and target tracking. Firstly, the state of each pixel point on the same synchronous detection line is judged in the probability model of pixel points. Secondly, the state of each synchronous detection line is estimated by maximum likelihood estimation so...
A novel approach to video detection, synchronous detection lines method, is proposed in this paper. In fact, it is a division mode for the pixel sets of the video images. Its division principle is that the pixels whose states change synchronously in the image series are divided into the same pixel sub-set. The combination form of these pixels is generally represented as the line segment in the application...
