As the rapid development of social media, now massive data are produced every day. We need to know about users' view and comment on a hot event so that the government and relevant departments can control and guide public opinion, and people can have a correct understanding of the event. So it is necessary to analyze these data. While it is difficult to dig out sufficient information from these data...
Intrusion detection plays a critical role in security of people's possessions. Approaches such as video-based, infrared-based, RFID, UWB, etc. can provide satisfying detection accuracy. However, they all require specialized hardware deployment and strict using conditions which hinder their wide deployment. Beyond communication, WLANs can also act as generalized sensor networks and there are several...
In the management of the online public opinion and Internet intelligent information, people need to obtain the content of the forum threads for further research on the topic emotion and the dissemination of forum topics. This paper presents a method based on templates to extract web forum contents. Proposed method overcomes the problem which caused by the change of the web pages structures and contents,...
This paper presents an efficient multiresolution video stabilization algorithm based on the Scale Invariant Feature Transform (SIFT) algorithm. The algorithm utilizes the Haar wavelet transformation of registered images, reducing the memory consumption while maintaining accuracy of the feature points, which we will quantitatively contrast in the paper.
This paper researched scale invariant feature transform (SIFT) which is feature extraction method of image processing, and it is stable for image feature registration. And image mosaic needs the fusion of overlapped region after the image registration. The research of image fusion in mosaic nowadays is concentrated on multi-resolution mosaic simply, and ignores the similarity of feature points among...
A de-noising method using wavelet transform and morphology for low light level image is presented. The intensity of noise field is different from the intensity of normal image region, which has reduce the quality of vision and after works of image processing such as segmentation, feature extraction and identification. Since there are a number of noises in low light level image, this paper did some...
