IQUAFLOW: A new framework to measure image quality
P. Gallés, K. Takats, M. Hernández-Cabronero +10
IQUAFLOW is a new image quality framework that provides a set of tools to assess image quality. The user can add custom metrics that can be easily integrated. Furthermore, iquaflow…
Lower Bounds on the Redundancy of Huffman Codes with Known and Unknown Probabilities
Ian Blanes, Miguel Hernández-Cabronero, Joan Serra-Sagristà +1
In this paper we provide a method to obtain tight lower bounds on the minimum redundancy achievable by a Huffman code when the probability distribution underlying an alphabet is on…
Coding Block-Level Perceptual Video Coding for 4:4:4 Data in HEVC
Lee Prangnell, Miguel Hernández-Cabronero, Victor Sanchez
There is an increasing consumer demand for high bit-depth 4:4:4 HD video data playback due to its superior perceptual visual quality compared with standard 8-bit subsampled 4:2:0 v…
Cross-Color Channel Perceptually Adaptive Quantization for HEVC
Lee Prangnell, Miguel Hernández-Cabronero, Victor Sanchez
HEVC includes a Coding Unit (CU) level luminance-based perceptual quantization technique known as AdaptiveQP. AdaptiveQP perceptually adjusts the Quantization Parameter (QP) at the…
