Channel-wise Feature Decorrelation for Enhanced Learned Image Compression

no code implementations16 Mar 2024 Farhad Pakdaman, Moncef Gabbouj

The emerging Learned Compression (LC) replaces the traditional codec modules with Deep Neural Networks (DNN), which are trained end-to-end for rate-distortion performance.

Pixel-Wise Color Constancy via Smoothness Techniques in Multi-Illuminant Scenes

no code implementations5 Feb 2024 Umut Cem Entok, Firas Laakom, Farhad Pakdaman, Moncef Gabbouj

Motivated by this, we propose a novel multi-illuminant color constancy method, by learning pixel-wise illumination maps caused by multiple light sources.

BL-JUNIPER: A CNN-Assisted Framework for Perceptual Video Coding Leveraging Block-Level JND

1 code implementation IEEE Transactions on Multimedia 2022 Sanaz Nami, Farhad Pakdaman, Mahmoud Reza Hashemi, Shervin Shirmohammadi

However, existing JND-based solutions estimate JND levels for each video frame and ignore the fact that different video regions have different perceptual importance.
