Embedded Compression for Embedded Intelligent Vision & Video System

点击翻译按钮获取中文摘要

Nowadays, video coding and computer vision algorithms are widely applied in mobile devices, such as smartphones and wireless sensor networks. While many of these devices are battery powered or even battery-less, a low energy consumption is crucial. In this research, I focus on reducing the dominant energy consumption of DRAM access by embedded compression.DRAM access power is proportional to its volume, so it can be reduced by compressing data before storing them to DRAM and decompressing data after fetched back. Hence, I researched on the embedded compression for embedded video and vision systems.In this year, I mainly focus on reducing the size of deep convolutional neural networks based on pruning, quantization and encoding, and submitted one journal paper.
