Bag of words (BoW) model, which was originally used for document processing field, has been introduced to computer vision field recently and used in object recognition successfully. However, in face recognition, the order less collection of local patches in BoW model cannot provide strong distinctive information since the objects (face images) belong to the same category. A new framework for extracting...
When the fused variables are independent or the statistics of variables are known perfectly, Kalman filter is rigorous and yields minimum mean squared error estimate. But in most situations, it is impossible to guarantee that the fused variables are independent and even might be highly correlated. In that case, it is possible to "over estimate" the statistics. CI algorithm can achieve a...
The article lists features of Gasar metal porous filter materials and problems of sintered metal porous filter materials. A mathematical model was created on the basis of analysis of fluid resistance, used as the main evaluation index of permeability of porous materials. The formulas of fluid resistance in pores of porous materials were obtained and the advantage of fluid resistance of Gasar filter...
In this paper, some counter-examples are given to analyze deeply several common easily confused basic concepts and theories in unary function calculus. Through the examples, it can seen that we must truly understand the basic concepts of advanced mathematics. In order to learn higher mathematics better; it needs us to have a deep understanding about the concept in unary function calculus. In this...
