In this paper, we present a novel 3D model alignment method by analyzing the voxels of 3D meshes and a visual similarity based 3D model matching and retrieving method using active tabu search. Firstly, each 3D model is voxelized and applied voxels based PCA transformation, then it is represented by six depth images which are projected by rendering in the PCA coordinate system. Hybrid descriptors are...
The gridding is an essential task for DNA microarray image analysis which will definitely affect the spot segmentation and intensity extraction. The accuracy and reliability of existing gridding methods depend on the artificial experience value owing to they can not dynamically determine the required processing parameters. In this paper, the gridding problem is turned into an optimizing problem by...
