Abstract: The need for better video coding technologies led to the development of several video coding standards, with High Efficiency Video Coding (HEVC) being the latest in the series. This thesis seeks to advance the state-of-the-art towards achieving real-time perceptually-optimized video coding schemes and their applications to advanced video codecs. We first focus on perceptual video coding, where we investigate techniques that enable video codecs to tractably optimize encoded videos for human visual perception while leveraging on existing video codec designs. A perceptually-relevant mean squared error-based perceptual quality metric is proposed and used to design perceptual mechanisms that can be easily incorporated into video codecs. An objectness-aware video coding scheme is also investigated. We then focus on fast video coding, where we investigate techniques that offer competitive trade-offs between encoder computational cost and coding performance. A fast encoding method that offers attractive encoding time savings with little coding losses is proposed.
