Achieving image compression by discarding duplicate image data

Abstract [en]

This thesis aims to investigate if an image can be compressed by discarding image data that can be considered interchangeable with other data in the same image with respect to a given error tolerance and see what effects that has on the quality of the image in question. The goal is to produce a file format design to handle this image structure and a prototype program that can produce these kinds of files by processing images. As this thesis shows, images can indeed be compressed this way but at high error tolerance levels the image quality is severely compromised and at lower tolerance levels, compressing an image is a very time consuming process. An advantageous aspect of this system however is that detail is preserved while parts that are less detailed are automatically more heavily compressed. The result of this work is a Java based prototype program with a graphical user interface that allows a user to load and view images of this new file format and also load and compress images of a variety of popular image formats. A number of suggestions on future development is also supplied, for instance applying this technique on video compression.
