This paper introduces a new lossy approach for compression of cartoon images. The image
is firstly partitioned into regions of roughly the same colour. The chain codes are then …

Obtaining a 3D medical visualization is a tedious process requiring several processing steps
(such as segmentation) and assigning various rendering parameters (such as color and …

This paper considers the use of interpolative coding for lossless chain code compression.
The most popular chain codes are used, including Freeman chain code in eight (F8) and …

To make the human-robot collaboration effective, it may be necessary to provide robots with
“senses” like vision and hearing. Task-oriented man-machine speech communication often …

A new method for encoding a sequence of integers, named Binary Adaptive Sequential
Coding with Return to Bias, is proposed in this paper. It extends the compressing pipeline for …

Abstract Burrows-Wheeler Transform, followed by Move-To-Front Transform, are often used
transformation techniques in data compression. They may reduce the information entropy of …

A lossless chain code compression algorithm consisting of Burrows-Wheeler Transform,
Move-To-Front Transform, and a modified interpolative coding is presented in this paper …

This paper introduces a new algorithm for Boolean operations on rasterized geometric
shapes that are represented with chain codes. The algorithm works in three steps. Firstly, the …

One of the most important and recurring tasks in managing a store is to provide accurate, up-
to-date price information to customers on the shelves. Manual updating of price tags has …

The advent of depth sensing technologies means that the extraction of object contours in
images-a common and important pre-processing step for later higher level computer vision …
