At present, screen image compression techniques are mostly designed for computer desktop, and there is still much room for improvement of the image compression quality and compression ratio, etc. when applied to scientific instruments workstation screen image. In order to solve such problems, this paper puts forward a kind of compression method applicable to scientific instruments workstation screen...
Fractal image compression is a relatively recent image compression method. Its basic idea is to represent images as a fixed point of a contractive Iterated Function System. Spiral Architecture is a novel image structure on which images are displayed as a collection of hexagonal pixels. But till date there are no available image capture or display devices to support this structure. Hence in order to...
In this paper, we have proposed a modified version of image compression/decompression algorithm using block optimization and byte compression method (BOBC). After BOBC, it is followed by run-length encoding and its block is optimised by varying block size. The proposed algorithm is very simple in implementation, fast in encoding time. Experimental results show that compression ratio of this algorithm...
