Paper Abstract

A new edge block coding mode of digital video coding is presented. For the detailed reconstruction of edge blocks, an adaptive block truncation coding is proposed using the properties of block truncation coding and intensity sensitivity of Human Visual System. To use this algorithm in video sequence coding, an edge block detection mechanism is devised and pixel reallocation, scan mode selection, 1D DPCM, and 2D run length coding are explained. Measured with objective and subjective criteria, the new algorithm is shown to have better performance than other algorithms.
