14 septembre @ 16 h 00 min - 17 h 00 min

The next IPI seminar will held on Friday, the 14th of September (4pm-5pm), in D010 room at Polytech.
The speaker will be Pr. Mai XU, who is associate professor of school of Electronic and Information Engineering, Beihang University.

Title of the seminar: « Embracing Intelligence in Video Compression »

​Abstract:
Recently, along with the explosion of multimedia content, visual communications have become increasingly prominent in communication networks, affecting the daily life of billions of citizens and millions of businesses in the world. The amount of data over networks is expected to grow almost 40-fold in the next five years. Given the limited spectrum, video applications have encountered the bandwidth-hungry bottleneck. The pioneering research on delivering the perceived content of human is relieving the bandwidth-hungry issue from the perspective of perceptual compression and coding, in which artificial intelligence (AI) techniques, such as computer vision and machine learning, have been actively studies.
In this talk, we mainly focus on perception-inspired video compression, which learns from human intelligence for significantly removing perceptual redundancy of video data. Specifically, our talk first presents our works in data-driven saliency detection, which can be used to explore perceptual redundancy of video. Based on saliency detection, we then discuss our approaches on perception-inspired video compression for dramatically removing redundancy of video compression, such that both bit-rate and complexity can be significantly reduced without any degradation on quality of experience (QoE). Finally, we briefly introduce our latest works in panoramic video (also called 360-degree video) compression, which improves rate-distortion through predicting viewports of panoramic video.
