  12月27日,韩国成均馆大学教授、视频压缩专家Byeungwoo Jeon应邀做客我校学者论坛。Byeungwoo Jeon在学校清水河校区宾诺咖啡作题为“Low complexity visual coding in compressed sensing approach”的学术报告,来自多个学院的师生参与本次学术分享。论坛由电子工程学院、IEEE Fellow朱策教授主持。

  在报告中,Byeungwoo Jeon介绍了他们实验室的最新工作:利用压缩感知技术构造了一种低复杂度的编码器和解码器。与传统视频编码先采样、后压缩的方式不同,这种新型的编解码器使用压缩感知技术直接进行压缩采样,并基于由随机矩阵采样得到的信息进行编码与图像重建。与传统方法相比,这种编解码器能达到与H.264相当的图像质量,而所消耗的计算和存储资源则大幅度减小,十分适宜在资源有限的环境下使用。

  Byeungwoo Jeon的学术报告十分注重研究背景和基础知识的铺垫,即使对视频编码技术了解有限的,也能在其反复讲解中对报告内容有清晰的把握。在照顾大框架介绍的同时,Byeungwoo Jeon还对其中的一些关键进行了介绍,例如采用根据图像的纹理复杂度自适应的进行抽样率调整,在环路滤波中采用一种加权滤波的方式取消DCT和IDCT变换步骤,进而加快运算速度减少功耗。

  Byeungwoo Jeon教授的分享不但帮助我校师生了解了编码技术的前沿热点,隐含在报告中的一些洞见也对师生们的科研工作有所启迪。在互动环节,我校师生就一些可能的创新点与Jeon教授进行了交流探讨。

  本次活动由人力资源部教师发展中心主办,电子工程学院、机器人研究中心承办。
