Enhanced browsing techniques for digital imagery facili tate the exploration process of large images often by using new ways to represent the image. Reduction of image con tent is such an approach often linked with need for strong processing power. To overcome this, we proposes the use of the Discrete Wavelet Transform (DWT), which inher ently separates detail and approximation of the image. By enhancing the detail and removing the approximation di rectly in wavelet domain, a very fast content reduction can be achieved. Due to its flexibility, JPEG2000 is used to shown the suitability of the approach for compliant station ary and remote image browsing.
