Just Noticeable Distortion-Based Perceptual Rate Control in HEVC
IEEE Transactions on Image Processing, 2020In this paper, we propose a just noticeable distortion (JND)-based perceptual rate control method for high efficiency video coding (HEVC). First, the JND factor of a coding unit has been mathematically shown to be an approximation of the average pixel ...

Video thumbnail extraction for HEVC
Signal Processing: Image Communication, 2017Abstract This paper proposes a thumbnail quality enhancement algorithm that uses a predefined weight table. Conventional thumbnail extraction algorithms in high efficiency video coding use a simple downsampling method to produce thumbnail images with low complexity, resulting in thumbnail quality deterioration.

IEEE international Symposium on Broadband Multimedia Systems and Broadcasting, 2012
All transformed coefficients in a TU (Transform Unit) are equally quantized in the HEVC (High Efficiency Video Coding) standard. Such an equal quantization is not efficient because the transformed coefficients in the TU are not equally distributed. Moreover, the quantized coefficients scanning order method in the HEVC standard takes into account the ...

2013 IEEE International Conference on Multimedia and Expo Workshops (ICMEW), 2013
Unlike previous video coding standards such as MPEG-2/H.262 and MPEG-4 AVC/H.264, the new video coding standard HEVC does not require a complementary field pair to be consecutive in decoding order. Each field is stored into a separate field buffer. However, some display systems only take frame buffers as input, so that two field buffers have to be ...

Saliency based perceptual HEVC
2014 IEEE International Conference on Multimedia and Expo Workshops (ICMEW), 2014Saliency represents the probability of human attention over the image therefore is important in understanding the importance of different areas in the image. In this paper, we consider how to utilize the saliency information in HEVC video coding. The graph-based visual saliency is incorporated with the quantization control in HEVC to reduce the bit ...

Residual Highway Convolutional Neural Networks for in-loop Filtering in HEVC
IEEE Transactions on Image Processing, 2018High efficiency video coding (HEVC) standard achieves half bit-rate reduction while keeping the same quality compared with AVC. However, it still cannot satisfy the demand of higher quality in real applications, especially at low bit rates.

HEVC Implementation for IoT Applications
2018 30th International Conference on Microelectronics (ICM), 2018Effective compression guarantees that IoT will continue spreading to cover various devices. High Efficiency Video Coding (HEVC), also known as H.265, is the most recent video coding standard; it introduces new coding methods compared to older popular standards. Such a change has a great impact on both encoder complexity and speed as it provides bitrate

CGS quality scalability for HEVC
2011 IEEE 13th International Workshop on Multimedia Signal Processing, 2011Scalable video coding provides an efficient way to serve video contents at different quality levels. Based on the development of emerging High Efficiency Video Coding (HEVC), we propose two coarse granular scalable (CGS) video coding schemes here. In scheme A, we present a multi-loop solution in which the fully reconstructed base pictures are utilized ...
