Image registration is a process to establish the spatial correspondence between the images of same scene, which are acquired at different view points, at different times, or by different sensors. In this paper, we propose an effective registration method for images acquired by multi-sensors, such as EO (electro-optic) and IR (infrared) sensors. Image registration is achieved by extracting features and finding the correspondence between features in each input images. In the recent research, the multi-sensor image registration method that finds corresponding features by exploiting NMI (Normalized Mutual Information) was proposed. Conventional NMI-based image registration methods assume that the statistical correlation between two images should be global, however images from EO and IR sensors often cannot satisfy this assumption. Therefore the registration performance of conventional method may not be sufficient for some practical applications because of the low accuracy of corresponding feature points. The proposed method improves the accuracy of corresponding feature points by combining the gradient orientation as spatial information along with NMI attributes and provides more accurate and robust registration performance. Representative experimental results prove the effectiveness of the proposed method.

Childhood obesity is harmful to health and growth. We had experienced a childhood obese patient. From Feb. 28. 2003 to July. 14. 2003. We applied Chegameuiyin-tang(體感薏苡仁湯), electrolipolysis and VLCD(very low calorie diet), behavioral therapy, aerobic exercise, infra-red therapy, auricular acupuncture, and aqua-massage. Through this obesity treatment during 5 months, total weight loss was 12.2kg, reduction of percent body fat was 13.4% (from 38.5 to 25.1), her condition and hepatic index(AST, ALT) was improved.
