The change detection method based on multi-temporal object was implemented by chi-square test and Gaussian distribution iteration to find the changed object in the past. However, trapped in the sample data does not obey the Gaussian distribution, the detection effect is not ideal. In order to fix this problem, a method based on law of cosines with box-whisker plot is proposed. First, the feature space...
By studying the Scale-Invariant Feature Transform (SIFT) operator, we know the process require calculate the whole scale spaces of the input image, costing the expensive time and taking up a lot of memory resources. Especially for the large aerial image, the SIFT operator can not process and doesn't generate keypoints. Therefore we implement the SIFT operator on large-format aerial images, and show...
For features extraction of image measurement and reconstruction from industrial parts images, this paper puts forward a mathematical model guided by CAD designed data which can detect image lines with high accuracy. Firstly, based on CAD data getting line initial values by projecting object line features through the conversion of 3D CAD coordinate and image, and then extracting a sequence of edge...
