Special Issue Information

Dear Colleagues,

In recent years, deep image/video coding technologies represented by deep learning have significantly outperformed traditional image/video coding formats such as JPEG and HEVC in terms of human perception and machine vision tasks. The coding quality of images/videos depends on various quality evaluation metrics, and novel perceptual metrics have led to higher requirements for image and video compression. At the same time, the development of large-scale foundation models has provided good data priors for image and video compression, creating possibilities for further enhancing the machine vision accuracy of image/video coding. However, for practical application deployment, designing low-latency and low-complexity image/video coding algorithms is still a key problem to be solved.

In this context, for this Special Issue entitled “Image and Video Coding Technology”, we invite original research and comprehensive reviews on, but not limited to, the following:

  • Advances in perceptual image/video coding;
  • Advances in lossy and lossless image/video coding;
  • Advances in point cloud coding;
  • Advances in machine vision-oriented image/video coding;
  • Advances in image/video compressive sensing;
  • Reinforcement learning and game theory for image/video coding;
  • Real-time video encoding;
  • Scalable Video Coding (SVC);
  • Enabling technologies for high-performance video coding;
  • Video coding for mobile communication;
  • Rate distortion theory for lossy image/video coding.

Neural network pruning has been widely studied for model compression and acceleration, to facilitate model deployment in resource-limited scenarios. Conventional methods either require domain knowledge to manually design the pruned model architecture and pruning algorithm, or AutoML-based methods to search the pruned model architecture but still prune all layers with a single pruning algorithm. However, many pruning algorithms have been proposed and they all differ regarding the importance they attribute to the criterion of filters. Therefore, we propose a hybrid search method, searching for the pruned model architecture and the pruning algorithm at the same time, which automatically finds the pruning ratio and pruning algorithm for each convolution layer. Moreover, to be more efficient, we divide the search process into two phases. Firstly, we search in a huge space with adaptive batch normalization, which is a fast but relatively inaccurate model evaluation method; secondly, we search based on the previous results and evaluate models by fine-tuning, which is more accurate. Therefore, our proposed hybrid search method is efficient, and achieves a clear improvement in performance compared to current state-of-the-art methods, including AMC, MetaPruning, and ABCPruner. For example, when pruning MobileNet, we achieve a 59.8% test accuracy on ImageNet with only 49 M FLOPs, which is 2.6% higher than MetaPruning. Full article
