Challenges and Current Approaches in Entropy Coding for Image and Video Compression
Abstract: Modern compression techniques are essential for storing and transmitting image and video content. Due to the increased usage of video data and the trend to higher resolution formats, there is a large interest in finding more efficient compression algorithms. The lossless coding of intermediate data, which is also referred to as entropy coding, is an integral part of all image and video compression schemes, since it eventually determines the bit rate of the generated bitstream.
In the first talk, I will give an overview of different state-of-the-art entropy coding approaches for image and video coding and highlight their relation to the problem of probability estimation. In particular, the different approaches will be compared with respect to their complexity and degree of adaptivity. In the second talk, I will present several new methods for improving the coding efficiency and reducing the complexity of entropy coding in modern video compression. These methods have applications within state-of-the-art video coding standards like HEVC (High Efficiency Video Coding) and VVC (Versatile Video Coding).
