IEEE Signal Processing Letters, 2010•ieeexplore.ieee.orgWe recognize that the key challenge in image compression is to efficiently represent and
encode high-frequency image structure components, such as edges, patterns, and textures.
In this work, we develop an efficient lossless image compression scheme called super-
spatial structure prediction. This super-spatial prediction is motivated by motion prediction in
video coding, attempting to find an optimal prediction of structure components within
previously encoded image regions. We find that this super-spatial prediction is very efficient …

We recognize that the key challenge in image compression is to efficiently represent and encode high-frequency image structure components, such as edges, patterns, and textures. In this work, we develop an efficient lossless image compression scheme called super-spatial structure prediction. This super-spatial prediction is motivated by motion prediction in video coding, attempting to find an optimal prediction of structure components within previously encoded image regions. We find that this super-spatial prediction is very efficient for image regions with significant structure components. Our extensive experimental results demonstrate that the proposed scheme is very competitive and even outperforms the state-of-the-art lossless image compression methods.
