In this paper, we develop a novel padding technique that guarantees the number of non-zero transformed coefficients after normal N x N DCT on the padded block ...

Shape-adaptive DCT (SA-DCT) provides a useful tool for coding of arbitrarily-shaped image/video segments which is indispensable to achieve object-based coding.

A new padding technique is introduced based on which the arbitrarily-shaped DCT can be implemented using normal N×N DCT, where the number of non-zero ...

In this paper, a new texture coding algorithm for arbitrarily shaped image segments is introduced. In contrast to other methods described in the literature, ...

We introduce a new padding technique based on which the arbitrarily shaped DCT can be implemented using a normal N×N DCT.

The proposed algorithm integrates the boundary pixel scanning technique into the boundary block grouping and merging technique, which aims to groups or ...

We develop a new set of shape-adaptive padding algorithms based on the technique of selecting a subset of the available basis functions of a complete N × N ...

Coding of arbitrarily shaped image segments is an important tool to achieve object-based coding, which is becoming more and more popular in today's ...

We introduce a new padding technique based on which the arbitrarily shaped DCT can be implemented using a normal N/spl times/N DCT. The new padding is carried ...

TL;DR: A new padding technique is introduced based on which the arbitrarily-shaped DCT can be implemented using normal N×N DCT, where the number of non-zero ...
