A byte-size multi-variable-length-code based string matching algorithm for Alpha image coding
According to the characteristics of Alpha image and the statistical characteristics of coding parameters of string matching algorithm,an Alpha image coding algorithm based on byte-size multi-variable long-length string matching was proposed.The algorithm firstly used a byte-type multi-variable long-...

| description | According to the characteristics of Alpha image and the statistical characteristics of coding parameters of string matching algorithm,an Alpha image coding algorithm based on byte-size multi-variable long-length string matching was proposed.The algorithm firstly used a byte-type multi-variable long-code scheme for joint optimization coding of multiple string matching coding parameters,the offset parameter was then encoded using a segmentation mapping scheme with proximity offset prioritization.Finally,the matching string length parameter was matched with a segmentation coding scheme.The experimental results show that compared with LZ4HC,zlib,PNG and HEVC (x265),the proposed algorithm has the advantages of ultra-low complexity and high coding efficiency. |
