This paper presents a video processing system that can track a human target across multi-cameras. The user can browse video clips from the system. When a target is identified by the user, the system can automatically track the target across different cameras. There are three main parts in the system. The first part is object segmentation by a Bayesian model. The second part is object tracking. The...
Background modeling is a key step of background subtraction methods used in the context of static camera. The goal is to obtain a clean background and then detect moving objects by comparing it with the current frame. This paper describes a novel fuzzy approach for moving object detection which is capable of processing images extremely rapidly and achieving high detection rates. This work integrates...
Motion detection is a fundamental and important part of many visual tracking systems and of other computer vision applications. In this paper, we present a robust and effective motion detection method for detecting foreground moving objects even with quick lighting changes and shadows in scenes. The proposed approach integrates YCbCr color features with texture by a fuzzy method based on Choquet integral...
In this paper, we propose a watermarking algorithm for color image based DCT and DWT. A binary image as watermark is embedded into green component or blue component of color image. The algorithm can satisfy the transparence and robustness of the watermarking system very well. The experiment based on this algorithm demonstrates that the watermarking is robust to the common signal processing techniques...
Calculation of image similarities is one of the key technologies for RBIR (Region-Based Image Retrieval) system. In this paper, a method of region-based calculating image similarity was proposed. For this method, firstly, the similarity of two regions with the combination features (color, texture and position), histogram and region shape features, was computed, respectively. Then, the similarity of...
In this paper, a K-means clustering (KMC) algorithm of automation determination the clustering number K is proposed, and a approach of region-based image segmentation is introduced based on our proposed algorithm. For this approach, firstly, a suitable color space is selected, the features of color, texture, and location are extracted, and the feature space is generated. Then, in this feature space,...
Approaches of ROI (regions of interest) confirmed and similarity calculated are key techniques for ROIBIR (regions of interest-based image retrieval) system. In this paper, two approaches of confirming ROI and a region-based similarity measure approach are proposed. Two approaches of confirming ROI which consider enough the visibility of image regions,the possibility of designating region and itpsilas...
