黄颂恩 %J 电子与信息学报 %D 1984 %I %X An adaptive transform coding method of image is presented, in which an image is devided into a number of image sub-blocks and two-dimensional symmetrie cosine transform is performed. And the bit-allocation map for adaptive quantization of transform coeffieients is obtained through estimation and transmission of some parameters of the sub-blocks. In the paper analytical and simulated experimental results of the method are given. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=5B3AB970F71A803DEACDC0559115BFCF0A068CD97DD29835&cid=1319827C0C74AAE8D654BEA21B7F54D3&jid=EFC0377B03BD8D0EF4BBB548AC5F739A&aid=EDC445E04FCF16F5&yid=36250D1D6BDC99BD&vid=B31275AF3241DB2D&iid=B31275AF3241DB2D&sid=F10601728A1E9BEA&eid=E57FE519484CFB70&journal_id=1009-5896&journal_name=电子与信息学报&referenced_num=0&reference_num=9
