2021 Picture Coding Symposium (PCS), 2021
The paper describes the novel aspects of deblocking filter in VVC. We demonstrate the insufficiency of HEVC deblocking filter when employing larger transform block sizes and describe the design changes made to enable reduction of the resulting blocking artifacts for both luma and chroma, while also allowing for parallel friendly processing ...

VVCS: Verifiable Visual Cryptography Scheme
2011 Seventh International Conference on Computational Intelligence and Security, 2011Visual cryptography is a cryptographic technique to achieve visual secret sharing. Shares are distributed to every participant and overlapping a number of shares can recover the original secret. The participants' cheating is discussed more in previous literatures.

Adaptive Color Transform in VVC Standard
2020 IEEE International Conference on Visual Communications and Image Processing (VCIP), 2020This paper provides an in-depth overview of the adaptive color transform (ACT) tool that is adopted into the emerging versatile video coding (VVC) standard. With the ACT, prediction residuals in the original color space are adaptively converted into another color space to reduce the correlation among the three color components of video sequences in 4:4:

Towards Fast and Efficient VVC Encoding
2020 IEEE 22nd International Workshop on Multimedia Signal Processing (MMSP), 2020Versatile Video Coding (VVC) is a new international video coding standard to be finalized in July 2020. It is designed to provide around 50% bit-rate saving at the same subjective visual quality over its predecessor, High Efficiency Video Coding (H.265/HEVC).

IC Voltage Variable Capacitors (VVC)
IEEE Transactions on Broadcast and Television Receivers, 1969This paper discusses the IC variable voltage capacitor (VVC) device design, its characteristics and application to the VHF tuner. Special measurement methods and tuner performance results are also discussed. It has been experimentally verified both by the device test data and by the VHF tuner performance results, that the multiple diffusion of VVC ...
