Simplification of color images using semi-flat morphological operators and statistical metrics
The aim of this study is to propose an algorithm for simplifying color images. The assumption is made that a set of reference colors is available and that this set indicates which...

Analysis of absorbing sets and fully absorbing sets of array-based LDPC codes
The class of low-density parity-check (LDPC) codes is attractive, since such codes can be decoded using practical message-passing algorithms, and their performance is known to app...
