Initial Parameter Estimation for Non-Linear Optimization -- Trigonometric Function
Tilo Strutz
Nonlinear optimisation techniques are commonly employed to minimise complex cost functions, with their effectiveness determined largely by the structure of the underlying error lan…
Range-Coder with fast Adaptation and Table-Based Decoding
Tilo Strutz, Roman Rischke
The transmission or storage of signals typically involves data compression. The final processing step in compression systems is generally an entropy coding stage, which converts sy…
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…
