Abstract
In this paper, a new low complexity Rate-Distortion optimization algorithm has been proposed. The proposed method can be employed with non-convex curves as well as convex curves. The new technique has been used in a hardware implementation of a JPEG2000 encoder. Simulation results indicate that the proposed algorithm is less sensitive to the shape of R-D curves in comparison with current algorithms. Compared to the exact method, our performance degradation is less than 0.43 dB. The low complexity of this algorithm makes it suitable for real time applications and in applications like Digital Cinema that have to process a large number of input data.
