Pedestrian detection, as an important task in video surveillance and forensics applications, has been widely studied. However, its performance is unsatisfactory especially in the low resolution conditions. In realistic scenarios, the size of pedestrians in the images is often small, and detection can be challenging. To solve this problem, this paper proposes a novel resolution-score discriminative...
The goal of object tracking is to estimate the state and trajectory of an interested target in a video sequence, thus both spatial and temporal information are of critical importance for tracking. However, most existing trackers usually determine targets just by the judgement like confidence from a single frame, which tend to treat tracking as a static detecting problem while neglecting the spatial-temporal...
Person reidentification is a key technique to match different persons observed in nonoverlapping camera views. Many researchers treat it as a special object-retrieval problem, where ranking optimization plays an important role. Existing ranking optimization methods mainly utilize the similarity relationship between the probe and gallery images to optimize the original ranking list, but seldom consider...
Appearance-based person re-identification namely matching the same pedestrian across disjoint camera views, is an increasingly research spot. Researchers have proposed many complicated appearance descriptions. The role of basic visual features is seldom investigated, e.g. color, texture features, which are the basis of descriptions. By analyzing the characteristics of data environments, we can get...
Car re-identification, searching a specific car object from a large-scale car image database, is investigated in this paper. Previous work mainly focuses on fixed pose and overlooks the special appearance. However, avoiding matching other poses would lead to coarse results of the car retrieval. And some special attributes like individual paintings which are greatly helpful for car retrieval have not...
In this paper we have implemented a mobile personalized sports video customization system for mobile users by using a novel approach. The system is based on the B/S architecture, with this architecture, the whole system can be divided into two parts: a friendly client browser on smart phones and an intelligent multimedia analysis server. For the client browser, a friend UI is designed for mobile users...
