Lossless 4:2:0 Screen Content Coding Using Luma-Guided Soft Context Formation
Hannah Och, André Kaup
The soft context formation coder is a pixel-wise state-of-the-art lossless screen content coder using pattern matching and color palette coding in combination with arithmetic codin…
Color Agnostic Cross-Spectral Disparity Estimation
Frank Sippel, Nils Genser, Hannah Och +2
Since camera modules become more and more affordable, multispectral camera arrays have found their way from special applications to the mass market, e.g., in automotive systems, sm…
Enhanced Color Palette Modeling for Lossless Screen Content Compression
Hannah Och, Shabhrish Reddy Uddehal, Tilo Strutz +1
Soft context formation is a lossless image coding method for screen content. It encodes images pixel by pixel via arithmetic coding by collecting statistics for probability distrib…
Improved Screen Content Coding in VVC Using Soft Context Formation
Hannah Och, Shabhrish Reddy Uddehal, Tilo Strutz +1
Screen content images typically contain a mix of natural and synthetic image parts. Synthetic sections usually are comprised of uniformly colored areas and repeating colors and pat…
