Three-dimensional shape-adaptive discrete wavelet transforms for efficient object-based video coding
In this paper, we present an object-based coding scheme using three-dimensional shape-adaptive discrete wavelet transforms (SA-DWT). Rather than straightforward extension of 2D SA...

Automatic Transformation of Bit-Level C Code to Support Multiple Equivalent Data Layouts
Portable low-level C programs must often support multiple equivalent in-memory layouts of data, due to the byte or bit order of the compiler, architecture, or external data formats...

Approaching Blokh-Zyablov Error Exponent with Linear-Time Encodable/Decodable Codes
Guruswami and Indyk showed in [1] that Forney's error exponent can be achieved with linear coding complexity over binary symmetric channels. This paper extends this conclusion...
