The Web Image Retrieval Based On JPEG2000 Compressed Domain

There are abundant of image information on Internet. How to manage the image resources efficiently and search the images that users need is becoming the people's researching topics. Because the image indexing based on compressed domain can attain the two objects of quick retrieval speed and good retrieval result at the same time, it has already been the research hotspot in recent years. The diversity of compression technologies leads to the diversity of searching technologies. Wavelet theory has been received broad attention and quick development. It could analyse the researching object on frequency domain and time domain concurrently and has multi-resolution analyse ability. The coefficients after wavelet transform could embody the part features of image information perfectly. These advantages promote people to study the image searching based on discrete wavelet transform domain. The new compression standard JPEG2000 adopts wavelet transform technology. Because of the priorities of the convention, it could be applied broadly on Internet, medicine, geology and data products. So it's very important to research the technologies about...
