Aiming at the realization of national feature extraction, an improved face recognition method is proposed in order to preserve some essential local features. Gabor featurebased on bi-directional two-dimensional principal component analysis ((2D)2PCA) is applied for face images. Firstly, Gabor features of different orientations and scales are extracted by the convolution of Gabor filter bank. Secondly,...
An image segmentation method is presented based on the inertial product energy to construct a good watershed structure for gradient level image and improve watershed segmentation. The inertial product energy can weaken the noises and tiny edges in gradient level image. Then a non-linear processing classification and filtering based on fusion and adaptive are employed to reduce the influence of a lot...
We have developed a web based UNIX file management system to facilitate different background users to use UNIX system. It is a cross-platform UNIX file management system that can be used from any web browser to execute file management operations on a UNIX server. Any user with a valid account on a UNIX server will be able to login to the server and create, delete, edit, download and upload files and...
Image processing is widely applied in the field of the biology and medicine domain, however, the study of the milk somatic cell image processing technology is a new topic currently. This paper carries on the pre-processing to the milk somatic cell images firstly. Then in the foundation of the selection of the color space and the analysis based on the SOM algorithm, the milk somatic cell color images...
The conformation is the main parameter in dairy cow appraisal; hence, it is necessary for the measuring and evaluating of dairy conformation to use machine vision technology in 3D reconstruction. The feature points detecting and matching are the pivotal steps in 3D reconstruction. The conventional SIFT feature points matching algorithm has shortcomings of too large search area and low efficiency,...
This paper proposes a method to solve the question of load balancing in cluster. This method is based on immune mechanism is proposed to solve load balancing in cluster. The algorithm can implement diversity of solution effectively, by immune memory library and acceleration and restraint of antibodies thickness. The testing results, compared with weighted round robin algorithm and weighted least connections...
Segmentation is the foundation for image processing, and it is also one of the basic works in image recognition and image analysis. This paper introduces SOM neural network and takes out principal component analysis with 12 components on the four colorful spaces RGB, YIQ, XYZ and Ycbcr. Then the methods 3PCA, the 2PCA and the 1PCA are used respectively to segment the color milk somatic cell images...
As VOIP, stream video, broadcasting, view-on-demand, online shopping and banking are more and more widely used; global network traffic is growing more and more. It is difficult to keep pace with increasing demands by continually adding capacity of network and global network performance is not satisfied. This paper discusses the design of J3manager - our three-layer network management system, which...
On LabVIEW, a temperature measurement and control system for constant temperature reciprocator platelet preservation box is designed based on Fuzzy-PID control. For temperature measurement part, we use multi-sensor data fusion algorithm to optimization data, and output fault early warming signal for sensors; Using Fuzzy-PID control algorithm to control the system, that will make the system has good...
