WaveGuide: A joint wavelet-based image representation and description system

Data representation and content description are two basic components requir ed by the management of any image database. A wavelet-based system, called the WaveGuide, which integrates these two components in a unified framework , is proposed in this work. In the WaveGuide system, images are compressed with the state-of-the-art wavelet coding technique and indexed with color, texture, and object shape descriptors generated in the wavelet domain durin g the encoding process. All the content descriptors are extracted by machin es automatically with a low computational complexity and stored with a low memory space. Extensive experiments are performed to demonstrate the perfor mance of the new approach.
