3D reconstruction based on high-level features, such as line and plane, is an important development trend in Digital Photogrammetry and Computer Vision. A novel method for extracting stratight line is presented, which can be illustrated as follows. Firstly, image is preprocessed by Wallis filtering that is used to enhance the image contrast and reduce the noise, so it is easy to extract more lines...
This paper has analysed the a priori algorithm performance, and has pointed out performance bottleneck question of the a priori algorithm. Currently those algorithms to mine association rules only pay attention to one aspect of efficiency or accuracy respectively. There is a paradox between efficiency and accuracy. In order to resolve to this conflict, a novel algorithm based on probability estimate...
Image mosaic technique is used to create vast scene images and panoramic images. It has widespread use value in the cultural heritage protection and virtual reality field. As we know, there are many methods of image mosaic, such as feature points and binary image region matching, etc. However, the traditional processing methods always ignore speed or precision or practical scale; that is to say, they...
A new self-adaptive algorithm based on the frequency signal of the moving transmitter was proposed and tested by the experiment, which could identify automatically the dynamic multi-interfaces of gas/oil and oil/water in the crude oil tank, and solve three tough problems to affect accurate measurement. The first, the separate process of the crude oil and water is dynamic, the interface changes inconstantly...
