What is ROI Coding

Chapter 29
Handbook of Research on Advanced Techniques in Diagnostic Imaging and Biomedical Applications
The Region Of Interest (ROI) coding it is a function that enables a non-uniform distribution of the image quality between a selected region (the ROI) and the rest of the image (background). ROI coding of medical images allows the compression of diagnostically important regions at better quality without affecting the visual assessment procedure, whereas areas like the background can be coded at lower quality in order to decrease image size and improve storage and/or transmission procedures.

Abstract
Medical images are often characterized by high complexity and consist of high resolution image files, introducing thus several issues regarding their handling. Current compression schemes produce high compression rates, sacrificing however the image quality and leading this way to unenviable examination. Region of Interest (ROI) coding has been introduced as an efficient technique for addressing such issues, by performing advanced image compression and preserving quality in diagnostically critical regions. This chapter discusses the basic ROI approaches and provides an overview of state of the art ROI coding techniques for medical images along with corresponding results.
