The goal of video summarization is to turn large volume of video data into a compact visual summary that can be easily interpreted by users in a while. Existing summarization strategies employed the point based feature correspondence for the superframe segmentation. Unfortunately, the information carried by those sparse points is far from sufficiency and stability to describe the change of interesting...
A practical line scan camera calibration technique for close-range photogrammetric applications is proposed. It is implemented by rigidly coupling the line scan camera to an auxiliary frame camera whose intrinsic parameters have been obtained in advance. Then, the calibration is divided into two independent stages. First, images of a 2-D dynamic pattern are acquired by the two cameras from several...
Accurately segmenting the moving objects from a sequence of captured video frames is a significant pre-condition for tracking and recognition of these moving objects. The challenge of segmenting the moving object is even harder when the background is dynamic and the camera used can change its zoom dynamically. Here, in this paper, we propose a new method to detect and segment moving object from a...
