Abstract

In order to find effective coding method, as much as possible eliminate the redundant information of original food packaging image and improve food packaging image compression efficiency, a kind of fast EZW food packaging encoding and decoding algorithm using linear indexing technique is proposed in this study. This kind of algorithm encodes and scans the linear sequence coefficients, which only needs less location information and improves the food packaging encoding and decoding speed to a certain degree, thus realizing a linear indexing technique similar to that in the non-linked list SPIHT. If the creation of linear sequence is placed before the coding of a group of food packaging images, then only the linear sequence is created once, the coding of these food packaging images can be implemented, so as to save a lot of coding time.

Keywords:

Decoding, EZW algorithm, food packaging encoding, linear indexing technique, two-dimensional scan,
