The image pipeline play a key role in improving the quality of color video image from the cmos/ccd image sensor in video surveillance system. The proposed pipeline is composed of automatic white balance, CFA color interpolation and illumination reducing. The automatic white balance module can reduce the color cast of one image which is undercoloured. By calculating the direction of centered pixel,...
Particle swarm optimization (PSO) is a new evolutionary computing method while it can not get good optimization performance because it easy to get stuck into local optima. This paper proposes a novel algorithm named improved PSO which combine proposed inertia adaptive PSO with partial particles Morlet mutation basing on basic PSO. Applies proposed algorithm and fuzzy entropy to image segmentation...
According to the deficiency of the traditional detecting method, this paper develops a set of intelligent automatically detecting system for the internal bore surface quality, which combined the image processing technology and pattern recognizing technology. The radius of image is detected using Least-squares fitting circle theory and circular degree is obtained through calculating circular surface...
The video monitoring system plays important roles in the military, public security, bank, transport, hotel, important storehouse, gymnasium, intelligent building, civilized community, airport and other fields. However, traditional monitoring system has many shortcomings. This thesis researches the intelligent monitoring system based on digital image processing, expounds the analysis technique of intelligent...
Based on the hyperchaos and discrete cosine transform (DCT) algorithm, combined with the Arnold scrambling method, a novel digital image watermarking algorithm is presented in this paper. The method makes use of Arnold method to weaken the correlation among the pixels of the watermarking and adopts srossler hyperchaotic sequence to encrypt the original watermarking. Furthermore, according to the character...
