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…
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…
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…
Image Segmentation For Improved Lossless Screen Content Compression
Shabhrish Reddy Uddehal, Tilo Strutz, Hannah Och +1
In recent years, it has been found that screen content images (SCI) can be effectively compressed based on appropriate probability modelling and suitable entropy coding methods suc…
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…
The Bjøntegaard Bible -- Why your Way of Comparing Video Codecs May Be Wrong
Christian Herglotz, Hannah Och, Anna Meyer +8
In this paper, we provide an in-depth assessment on the Bjøntegaard Delta. We construct a large data set of video compression performance comparisons using a diverse set of metrics…
Optimization of Probability Distributions for Residual Coding of Screen Content
Hannah Och, Tilo Strutz, André Kaup
Probability distribution modeling is the basis for most competitive methods for lossless coding of screen content. One such state-of-the-art method is known as soft context formati…
