Image segmentation is a very important research content in the fields of computer vision and pattern recognition. As the basis for image understanding and image analysis it is always receives high attention. At present in those commonly used segmentation methods of contrast ratio, margin and grayscale detection the threshold processing is one of the most effective. The threshold methods can also be...
Segmentation of digital image is an important link in digital image processing. According to the improved algorithm of PCNN's basic simplified model (Pulse Coupled Neural Network, PCNN) and the theory of immune algorithm the paper has studied the realization of intelligent OTSU image segmentation method and made a design of the OTSU image segmentation immune algorithm with self-adaptive determination...
Infrared image edge is very important in military object detection treatment. Based on the traditional edge detection algorithm the present paper adopts wavelet phase conversion filtration on wavelet transformation and lateral inhibition network to detect infrared image in accordance with infrared image features. The simulation test has proved that it can effectively solve the contradition between...
As an important part in the computer technical teaching system, the IT practical teaching has paid close attention to the teaching links. It is the teacherspsila concern how to train the studentspsila creativeness, operating skills, analyzing and solving abilities. This article puts forward the corresponding counter-measures beginning from the construction of the IT teaching practical team and the...
In this study, a hybrid data mining methodology, rough set based support vector machine (RS-SVM) model, is proposed to explore stock market tendency. In this approach, rough set is used for feature vectors selection to reduce the computation complexity of SVM and then the SVM is used to identify stock market movement tendency based on the historical data. To evaluate the forecasting ability of RS-SVM,...
As infrastructure of shared services, Web Services provides possibility for business coordination and interoperability under distributed computing environment. However, the traditional centralized Web Services architecture has its limitation and peer-to-peer computing has become a new mode for network computing on the current Internet. This paper presents an collaboratively design method of Web Services...
