Cell behaviors including adhesion, migration, proliferation, differentiation and apoptosis, etc. deeply influence tissue formation, regeneration, and even the function of whole tissue or entity. Optically-induced electrokinetic (OEK) patterning is an efficient method to guide cells to grow and form the desired structure on a substrate and hence becomes an effective approach to the study of cell behaviors...
Iris segmentation is an essential module in iris recognition because it defines the effective image region used for subsequent processing such as feature extraction and matching of the iris. Traditional iris segmentation methods often involve in searching large region and the arithmetic is complex. Some suppose that pupil and iris are concentric circles, but most of time, the two circles are not concentric...
This paper presents a new face recognition method based on the analysis of local features. Firstly, we can get the images of magnitude by means of analyzing face images with the Gabor wavelets. Secondly, the magnitude images are divided into blocks, then principle components analysis (PCA) could be directly used to all the blocks to construct the feature space. Finally, all the blocks of images are...
We introduce the use of over-complete spherical wavelets for shape analysis of 2D closed surfaces. Bi-orthogonal spherical wavelets have been shown to be powerful tools in the segmentation and shape analysis of 2D closed surfaces, but unfortunately they suffer from aliasing problems and are therefore not invariant under rotations of the underlying surface parameterization. In this paper, we demonstrate...
In order to solve the problem of large-scale image retrieval for complex images, this paper presents a novel ROI-based image retrieval algorithm. In this algorithm, a new color image segmentation algorithm based on information mutation is used to divide an image into several target areas firstly; then the features of image regions are extracted; finally, a new similar measurement criterion is defined...
