Compression and Transmission

Bild

In the past years our research group has been investigating algorithms that drastically depart from “Motion Compensated DPCM/Transform (MC-DPCM)”. Our prime intention is to allow ourselves a completely “fresh view” on how non-linear dependencies between pixels and motion in images and video can be described and harvested for compression. To this end we employ non-linear machine learning algorithms that explore dependencies between vast amounts of pixels in images and video sequences. Our current approaches are based on non-linear Kernel methods, Steered Mixture of Experts networks (MoE) and Restricted Boltzmann Machines and show strong resemblance to recent work on deep neural networks. Our experiments give hope that our networks may provide far better visual quality compared to DPCM/Transform approaches in the long run - presently we can illustrate this at very low and ultra low rates only. mehr zu: Compression and Transmission
