Abstract
In this paper, we propose the macroblock-level adaptive dynamic resolution conversion (DRC) technique usable by encoder to decide to reduce the resolution of input image on block-by-block basis for better compression efficiency. By reducing the spatial resolution of the block in the proposed scheme, it provides additional compression. As a proper resolution of a block is selected adaptively in the rate-distortion optimized way, more flexible coding is supported to adapt to the feature of image. Simulation based on the state of the art codec H.264 standard demonstrates that the proposed scheme has better performance than H.264 in terms of rate-distortion.
