A Low-Complexity Embedded Compression Codec Design With Rate Control for High-Definition Video

Three‐dimensional separate descendant‐based SPIHT algorithm for fast compression of high‐resolution medical image sequences

“…Considering the specialty of medical images, lossy must be within a certain extent. Referring to [23], as long as the value of PSNR is more than 50 dB, the distortion is considered to be acceptable. For images of size 512 × 512, the lowest PSNR of our proposed algorithm is ∼56–69 dB when bit rate is 0.125.…”

Enhanced Adaptive Approach of Video Coding at Very Low Bit Rate Using MSPIHT Algorithm

“…A decoder is used to synthesize by choosing virtual view via depth-image-based rendering. The shaped sub-block motion prediction can point to very small prediction residuals; it acquires an overhead for transmitting the dividing boundaries for sub-block identification at decoder [7].…”

Lossless image compression algorithm and hardware architecture for bandwidth reduction of external memory

“…Embedded compression (EC) is an efficient technique [14] to compress the data before storing them into off‐chip SDRAM, and decompress the data fetched back from SDRAM. There are some EC algorithms and architectures reported in the literature [14–30], lossy EC with fixed compression ratio (CR) and lossless EC with variable CR, as well as block‐based and line‐based EC targeting for different applications such as encoding and display. Lossy EC algorithm with fixed CR is straightforward with simple and efficient data organisation; however, has obvious shortcomings.…”

“…There are some literature regarding lossy reference image compression [15–17], some works proposed dual‐mode, lossy and lossless, EC algorithms for memory bandwidth saving [18, 19]. In comparison, more papers proposed lossless EC algorithms [20–29].…”
