This paper presents a fast method to estimate the required bits to encode a block of video data. The proposed method uses forward adaptive quantization (which uses the current sample information, not available at the decoder, to scale the sample value before and after quantization) to estimate the actual rate-distortion cost. Rate estimation has many applications in the art of video coding, where a coding decision should be made based on the optimality of a rate-distortion pair. As an example… CONTINUE READING
