FaSST: Fast Sparsifying Secondary Transform
Darukeesan Pakiyarajah, Samuel Fernández-Menduiña, Eduardo Pavez +2
Data-dependent secondary transforms, which aim to decorrelate coefficients of a separable primary transform, can improve residual coding efficiency; however, their deployment is of…

Joint Optimization of Primary and Secondary Transforms Using Rate-Distortion Optimized Transform Design
Darukeesan Pakiyarajah, Eduardo Pavez, Antonio Ortega +4
Data-dependent transforms are increasingly being incorporated into next-generation video coding systems such as AVM, a codec under development by the Alliance for Open Media (AOM),…
