Deringing and deblocking dct compression artifacts with efficient shifted transforms
A new method, using weighted combinations of shifted transforms, is developed for deringing and deblocking DCT compressed color images. The method shows substantial deringing impr...

Value Compression for Efficient Computation
A processor’s energy consumption can be reduced by compressing values (data and addresses) that flow through a processor pipeline and gating off portions of data path elements th...

Lossless Compression of Color-Quantized Images Using Block-Based Palette Reordering
Abstract. It is well-known that the lossless compression of color-indexed images can be improved if a suitable reordering of the palette is performed before encoding the images. In...
