Multi Rates and Resolutions SPIHT with Low Memory

Yahya Ali Lafta AL Husseini

Abstract: For improvement a highly scalable image compression system in order at sizes (resolutions) and qualities (bit rate) are obtained to obtain simply decoding that is achieved by a compressed image. Since, there are many users when the Internet is used and into required that is various user's request. Thus, need how can able to induce that without complexity and much data can be has quality and preserve their size. Therefore, a novel algorithm dominated Highly Scalable-Single List-SPIHT (HS-SLS) is proposed to introduce those purpose. The adaptable bit-stream which is created from HS-SLS algorithm when that is both rate scalable and resolution are gotten as a robustly scalable bit-stream. This can readily its encoder, at any bit-rate involving, can be modified to different resolution requirements, without the required to decode the bit-stream, a very straightforward scaling process that is implemented on-the-fly. An unique feature of the novel algorithm is that due to its easy memory management it has low requirement and low memory complexity. As well as, the size can be established which avoid the dynamic memory allocation problem due to the size of the applicable memory is stationary. For hardware enforcement, the HS-SLS algorithm very convenient due to its merits. As compared to the original SPIHT algorithm that, for these worthy features is very petty shorthand in the algorithm's performance, the price is paid.
