In this paper, we propose and evaluate cloud services for high resolution video streams in order to perform line detection using Canny edge detection followed by Hough transform. These algorithms are often used as preprocessing steps for various high level tasks including object, anomaly, and ...
我在OpenCV(c ++)中实现了Hough线变换,但是霍夫空间中出现了奇怪的伪影。下图显示了霍夫空间。距离rho表示在行中,而180列代表从0到179度的角度。如果你放大第45和135列,你会看到一个垂直的线,有交替的暗色和亮色像素。 http://imgur.com/NDtMn6S 对于更高的阈值,围栏的线被很好地检测到,但当我降低阈值时...

On the basis of this,at first,extract the edge contour of gear by taking advantage of improved self-adaptation median filter and threshold segmentation and edge detection and label,then it has carried on actual measurement to straight-cut gear with keyway by using random Hough transform to get ...
Then, in this research by using Hough Transform of the edge image of mouth and difference between the lengths of both eyes has been proposed to detection of best-shot face image with considered of direction and inclination. 展开 关键词: Gauss-Laplacian filter Hough Transform face direction ...
A good edge detection kernel will enhance the differences between neighboring pixels, and reduce the strength of a pixel with similar neigbors. I would start by looking at the Sobel operator. This might not return results that are immediately useful to you; however, it will get you far closer...

The edge detection process can be broken down into four basic transformations, modifying the image from the original presentation to the final edges one. The adoption of this framework makes the process far more understandable, and offers an starting point for the combination and comparison of diffe...
and the edge was detected by applying "corrosion" of mathematics morphology.Finally,the detection and localization of the path edge were realized based on Hough transformation.The experimental result indicates that,this method has a better compatibility to the complicated path environment,and enhances ...
