The geometric features of images, such as edges, are difficult to represent. When a redundant transform is used for their extraction, the compression challenge is even more dif...
In fractal image compression a partitioning of the image into ranges is required. In our previous work [1] we have proposed to find good partitionings by means of a split-andmerg...
File systems using non-volatile RAM (NVRAM) promise great improvements in file system performance over conventional disk storage. However, current technology allows for a relative...

We describe a compression scheme for the geometry component of 3D animation sequences. This scheme is based on the principle component analysis (PCA) method, which represents the ...
In compressed sensing we seek to gain information about vector x ∈ RN from d << N nonadaptive linear measurements. Candes, Donoho, Tao et. al. ( see e.g. [2, 4, 8]) propos...
