Abstract
A rate control algorithm is introduced to the JPEG XR still image compression algorithm, thereby allowing the user to compress an image to a target bit-rate. Using ρ-domain analysis, we showed a strong linearity relationship of the rate function R(ρ). This allows us to accurately estimate the rate-distortion function, and thus control bit-rate of the JPEG XR encoder.
