Utility-Driven Adaptive Preprocessing for Screen Content Video Compression

Utility-Driven Adaptive Preprocessing for Screen Content Video Compression Abstract: In this work, we propose a utility-driven preprocessing technique for high-efficiency screen content video (SCV) compression based on the temporal masking effect, which was found to be a fundamental attribute that plays an important role in human visual perception of video quality, but has not been […]


Optimal Symbiosis and Fair Scheduling in Shared Cache

Interactive Visual Discovering of Movement Patterns from Sparsely Sampled Geo-tagged Social Media Data Abstract Social media data with geotags can be used to track people’s movements in their daily lives. By providing both rich text and movement information, visual analysis on social media data can be both interesting and challenging. In contrast to traditional movement data, the sparseness and irregularity ofsocial media data increase the difficulty of extracting movement patterns. To facilitate the understanding of […]
