OVERVIEW OF THE IMAGE COMPRESSION TECHNIQUES
FOR CREATING DIGITAL ARCHIVES AND PRESENTATION
ON THE WEB
Abstract. In this
short tutorial traditional and new image compression techniques are presented.
By means of different examples, the advantages and drawbacks of various methods of
image compression are considered. This tutorial focuses on the application of new,
wavelet-based compression techniques, which are especially suitable for the
Internet presentation of scanned documents.
This chapter is available as one-day (6-hour) training package for
seminar: the text with remarks for trainer, references and a collection of
PowerPoint slides.
