| Outline of Annual Research Achievements |
This research aims at reducing the complexity of the latest video compression standard Versatile Video Coding (VVC), from the aspect of both algorithm and architecture. For the algorithm, we developed a fast intra encoding for video coding for machine (VCM) framework, and a low complexity convolutional neural network filter. For the architecture, we proposed a reconfigurable multiple transform selection architecture for VVC.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
This year, we proposed a fast VVC intra coding method which aims at reducing machine-to-machine connection in the IoT society. The results have been presented in the CAS-society flagship conference ISCAS. In addition, we also developed a reconfigurable architecture for VVC transform. The related results are published in IEEE Transactions on Very Large Scale Integration Systems. Regarding the neural network extension beyond VVC, we developed a low-complexity filter and the results are published in the journal of IEEE Multimedia.
We also present several other international conferences.

| Strategy for Future Research Activity |
There are two targets. For the algorithm, we plan to continue the work on fast intra coding for machine. Currently, we only attempted the object detection and instance segmentation. We will evaluate and analyze more machine vision tasks in the future. For the architecture, we aim at designing an area-efficient architecture for VVC adaptive loop filter.

| Causes of Carryover |
The CPU server was not purchased last year, and there was no travel fee last year due to Covid-19. This year, I plan to buy a server at first, and then use the remaining budget to attend an international conference.
