法国雷恩国立应用科学学院Joseph RONSIN教授将于10月13日访问yh533388银河，进行图像表示与压缩方面（Image representation and compression）的学术报告，并将进行为期20天（10月13日至11月4日）的系列讲学。
此次Joseph RONSIN 教授受信息学院江铭炎教授邀请，作为yh533388银河流动岗位特聘教授再次来yh533388银河讲学，旨在进一步加强双方已建立起的合作联系，推动双方在信号处理等领域的学术交流。Joseph RONSIN 教授于1972年在法国雷恩第一大学（University of Rennes, France）获得电子学硕士学位，于1977年在雷恩国立应用科学学院（INSA-RENNES）获得了博士学位。 1989年起，他担任雷恩电子通讯研究所 (IETR)图像与遥感实验室主任，并任INSA-RENNES教授。Joseph RONSIN 教授已在图像分析与压缩方面拥有多项工业授权，发表论文著作 130 余篇。
课程介绍：
IMAGE REPRESENTATION and COMPRESSION
Lectures are dedicated to source coding of still images and video. These lectures must permit the apprehension of the essential aspects of representation and compression for images. Representation has the objective of a reduction of corresponding data. After some brief reminders on Information Theory and human vision, then using Signal Theory, main coding techniques will be presented and illustrated. Standards for still images: JPEG and JPEG 2000 will be introduced with also standards for video: MPEG-1,2,4. Exercises will be developed in parallel, on one hand at the blackboard and on the other hand with dedicated software.
