Many image deblurring algorithms perform blur kernel estimation and image deblurring by assuming the blur type and distribution are already known. However, in practice such information is not known in advance and must be estimated using local blur measures. In this paper, we revisit the image partial blur detection and classification problem and propose several new or enhanced local blur measures...
The traditional algorithm of GNSS orientation using LAMBDA for single frequency receiver, couldnpsilat estimate the integer ambiguity in a little time, sometimes, couldnpsilat find the exact value. Based on the theory of Rough integer mapping, we get a new algorithm for the estimation of integer ambiguity to solve the problems we meet. Searching algorithm with granularity changing could improve the...
Estimating the number of people passing a gate or a door provides useful information for video-based surveillance and monitoring applications. This paper describes a robust method for bi-directional people counting. The method includes three steps: moving people detecting, tracking and counting. A new algorithm of detecting for moving people based on edge detection is proposed. We construct a foreground/background...
An improved object tracking scheme is presented based on the Kalman filter and mean-shift approach. And this scheme is robust to disturbance and occlusion of both the object and the scene. The object is selected by using FG/BG detection and represented by its center point and probability distribution. The mean-shift approach estimates the object position based on the result of the Kalman filter. A...
