作者: Narayanan, Sathiya Makur, Anamitra Nanyang Technol Univ Sch Elect & Elect Engn Singapore 639798 Singapore
In some surveillance videos, successive frames exhibit correlation in the sense that only a small portion changes (object motion). If the foreground moving objects are segmented from the background they can be coded i... 详细信息

作者: Cook, Gregory W. Kalker, Ton Hewlett Packard Corp Palo Alto CA 94304 USA DTS Inc Calabasas CA USA
Presented here is a description and analysis of the N-point sparse discrete cosine transform (SDCT), where N is a power of two, which retains all of the properties of the parent DCT such as linearity, energy compactio... 详细信息

19th IEEE International Conference on Image Processing (ICIP)
作者: Cook, Gregory W. Kalker, Ton Futurewei Technol Inc Santa Clara CA 95050 USA
In this paper we develop an effective method for arbitrary shape coding based on a four-point DCT. The improvements results from two sources: (1) an effective use of the DCT by efficiently inducing zero-valued transfo... 详细信息
