A Recursive Gsa Acquisition Algorithm for Image Compression
نویسندگان
چکیده
Culik and Kari introduced the use of gener-alised stochastic automata (GSA) as a method of digital image compression. The construction of a GSA from an image is a kind of automaton acquisition, although with special characteristics because reproduction is not required to be lossless. In this view an image is a kind of-nite formal language. We detail experimental and theoretical results concerning a simple, re-cursive GSA acqusition algorithm and discuss directions for future research.

Image compression is one of the important research fields in image processing. Up to now, different methods are presented for image compression. Neural network is one of these methods that has represented its good performance in many applications. The usual method in training of neural networks is error back propagation method that its drawbacks are late convergence and stopping in points of lo...

Image data require huge amounts of disk space and large bandwidths for transmission. Hence, imagecompression is necessary to reduce the amount of data required to represent a digital image. Thereforean efficient technique for image compression is highly pushed to demand. Although, lots of compressiontechniques are available, but the technique which is faster, memory efficient and simple, surely...

It is well known that digital images can be generated by generalised stochastic automata (GSA). This fact has been taken as the basis for image compression by storing a GSA rather than the image that it generates. This paper investigates fundamental relationships between the parameters of GSA and their generated images. In particular, we are interested in expressing the magnitude of GSA weights...

A lot of researchs have been performed in image compression and different methods have been proposed. Each of the existing methods presents different compression rates on various images. By identifing the effective parameters in a compression algorithm and strengthen them in the preprocessing stage, the compression rate of the algorithm can be improved. JPEG is one of the successful compression...

Compression can be done by lossy or lossless methods. The lossy methods have been used more widely than the lossless compression. Although, many methods for image compression have been proposed yet, the methods using intelligent skipping proper to the visual models has not been considered in the literature. Image inpainting refers to the application of sophisticated algorithms to replace lost o...
