A detection method of moving targets in deep space is researched based on technology of image registration. According to the characteristics of deep space image information, a SUSAN feature point extraction algorithm is modified to inhibit isolated noises which are similar to sidereal feature points, and it effectively eliminates isolated noises. The geometric constraint among stars in the star image...
This paper explores the use of quadratic mutual information as a similarity criterion for dense, non-rigid registration of medical images. Quadratic mutual information between two random variables has been recently proposed as Euclidean distance between the joint density and the product of the marginals. It has been shown to have a smooth sample estimator, that can be computed without having to use...
Thermography captures the temperature distribution of the human skin and is employed in various medical applications. Often it is useful to cross-reference the resulting thermograms with visual images of the patient, either to see which part of the anatomy is affected by a certain disease or to judge the efficacy of the treatment. An attractive approach to provide this information is to overlay the...
