....a function of the JPEG Quality Factor. However, a data independent predictor of compressed size had low accuracy. This is unsurprising: JPEG compression ratios depend on image content, and cannot be predicted from image size alone. My results here are broadly in agreement with those of Han et al. [44], who studied JPEG transcoding for a large number of web images. They show that, for a fixed JPEG level: There is a linear correspondence between uncompressed and compressed image size, but with a large amount of noise, i.e. variation across images. There is a better linear correspondence ....

....the desired fidelity (if a higher fidelity version is cached) iii) sending a lower fidelity cached version than the one requested (during periods of heavy loads) or (iv) by downloading the requested version from the server. Although the use of transcoding in web proxies has been investigated [6, 7], techniques for combining transcoding and caching techniques to reduce the overall resource usage at the proxy have not received much attention. Further, techniques to adapt the transcoding process to network conditions, proxy load and changing client requirements have not been explored. Our ....
....load conditions. We have implemented learning policies for adaptive proxies, which choose between server downloads and local transcodings based on the recent history of the particular client server pair. Unlike prior approaches that choose between the two extremes of transcoding and no transcoding [7], our proxies can support a continuum of choices and use current system conditions to make an appropriate choice on a per request basis. Adaptive Model. Our adaptive model ensures that policy decisions are governed by the current prevailing conditions; further, the model chooses the least ....

....to build distributed computing systems. Our system focuses on supporting application level hando#, it can easily incorporate the concept and functionalities that Jini or CORBA introduce. Using proxy architecture to perform distillation or transcoding of multimedia data has been investigated[14][5] by multiple research groups. However, our architecture goes one step further by incorporating session control and management with the content adaptation mechanism. IETF has proposed a family of standards[15] 16] 17] to support session initialization and set up for the applications like ....
