Sub-pixel edge detection
4.0
Digital Image edge detection for image segmentation, image analysis areas such as object recognition, shape extraction
Very important basis. At the time of image understanding and analysis, the first step is often the edge detection. At present, the
Edge detection has become one of the most active topics in machine vision, it is very important to study
On the significance and practical value. Traditional detection accuracy of edge detection method could only achieve a pixel
Levels, however, with the rapid development of science and technology, increasing demands of industrial applications such as detection accuracy,
Traditional approach to edge detection of pixel-level have been unable to meet the needs of actual measurements, and therefore need higher precision
Edge detection method, namely subpixel edge detection method. Sub-pixel edge detection technology in this article were deep
Into the study, study main contents include the follow
