Noise removal operation is commonly applied as pre-processing step before subsequent image processing tasks due to the occurrence of noise during acquisition or transmission process. A common problem in imaging systems by using CMOS or CCD sensors is appearance of  the salt and pepper noise. This paper presents Cellular Automata (CA) framework for noise removal of distorted image by the salt an...

image retrieval is an important research field which has received great attention in the last decades. in this paper, we present an approach for the image retrieval based on the combination of text-based and content-based features. for text-based features, keywords and for content-based features, color and texture features have been used. query in this system contains some keywords and an input...

A novel quaternion color representation tool is proposed to the images and videos efficiently. In this work, we consider a full model for representation and processing color images in the quaternion algebra. Color images are presented in the threefold complex plane where each color component is described by a complex image. Our preliminary experimental results show significant performance impro...

Color perception is of paramount importance in applications, such as digital imaging, multimedia systems, visual communications, computer vision, entertainment, and consumer electronics. Color is essential in digital cinematography, modern consumer electronics solutions, and digital photography system such as digital cameras, video displays, video-enabled cellular phones, and printing solutions...

application of additives is one of the proper solutions in quality enhancement in bakery products such as gluten matrix promotion, softness and unity of the texture and delay in staling which are effectives on shelf life and marketability of the bread. so the aim of this study was to investigate the synergistic effect of datem, ssl and e471 as an emulsifier in level of 0.2% and 0.5% humectants ...

I. Introduction With rapid progress of memory chip, image processing LSI, and personal computers (PC), cost-effective PC-based image processor is sufficiently realizable. This paper describes Video Workstation, a newly-developed video ~rocessing system, that features both a high-speed image processing board which contains a microprogrammable VLSI chip, and multimedia processing. The system cons...
