In this paper we propose a robust sparse based visual tracking method by exploiting local representations in a particle filter framework. We construct a Multi-level Local Dictionary which consists of positive templates and negative templates for discriminative model, Which divide the positive and negative dictionary into two levels called static templates and dynamic templates, respectively, thus...
Object recognition is a wide applied task in computer vision. Many fine-grained object recognition approaches are proposed in recent years to detect the same species objects effectively at subordinate-level. In this paper, we present a novel fine-grained vehicle recognition by utilizing collaborative feedback scheme of detection-classification-tracking in surveillance video. We collect a labeled data...
In this paper, we propose a novel collaborative appearance model for robust human tracking by exploiting both object and motion information in the bayesian framework. In contrast to most existing methods which use low or high-level visual cues, we use mid-level visual cues via superpixel with sufficient structure information to represent the object. In our work, the collaborative appearance is modeled...
The technology of Geographic Information System is applied widely in urban planning. In this paper we will discuss the application, development and exiting problems of geographic information system in urban planning. Through these studies, we hope geographic information system will serve for the urban planning better.
Online interaction was critical in underpinning the learning process in E-learning, and a framework for resource-oriented interactive learning, aiming to promote deep interaction among learners, resources and resource creators was proposed in this paper. Specifically, much research has been done to realize the interaction between learners and resources, recombination of resources and their presentation...
Numerous studies have reported that the time-series terrestrial parameters such as the Normalized Difference Vegetation Index (NDVI), Leaf Area of Index (LAI), Fraction of Absorbed Photosynthetic Active Radiation (FPAR), derived from NOAA/AVHRR, SPOT/VEGETATION, TERRA or AQUA/MODIS, have played significant roles in researching the global environment, terrestrial ecosystems and related ecological researches...
AVS-M is the recent mobile video coding standard of China. Currently, ARM cores are widely used in mobile applications because of their low power consumption. In this paper, a scheme of the AVS-M decoder realtime implementation on 32 bit MCU RISC processor ARM920T (S3C2440) is presented. The algorithm, redundancy, structure and memory optimization methods to implement AVS-M realtime are discussed...
