Abstract: Color information is very important in setting the style of images, but always influenced by internal and external imaging factors. For this reason, it is necessary to eliminate color inconsistency between different views in multi-view imaging. Up to now, many color transfer methods have been proposed mainly for vivid color appearance, in which the mean, variance, or covariance information are used to transfer color. In this paper, by taking the advantage of the principal component analysis (PCA) and independent component analysis (ICA), a general color correction framework is proposed. We first analyze the correction property for target image and source image. Then we perform global PCA color correction if global correction property satisfied. Otherwise, we separate the independent signal sources by dominant color extraction, and establish color correction relations between independent sources. Finally, we combine the ICA correction results to get the final corrected image. The Experimental results show that well subjective and objective performances can be achieved with the proposed method.

Abstract: The paper presents a health data monitoring and transmitting system for chronic or after heart operation falls at home-site of patient. It consists of vital signs measurement such as electrocardiogram, heart rate, and blood pressure and body temperature in real-time etc. The proposed system can monitor the patients and emergency communication with long-distance transmitting system via global positioning system engine board. A prototype of this system has been developed and implemented. It has been real tested by specific physician at Maharaj hospital, Chiang Mai. The system enables the patients to do the real-time monitoring his/her vital signs conditions and examine other kinds of the patient’s data from the computer database for 24 hours each day and the hospital’s monitoring centre can enables the patients position and vital signs data. The results from this research will enable the local industry to manufacture the instruments with high reliability to be used in Thailand. At a much lower cost than the imported ones.

Keywords: vital signs, heart rate, blood pressure, body temperature, chronic patient, hospital’s monitoring centre.
