WebThe Limitations of the Hough Transform are described in more detail on Wikipedia. The efficiency of the Hough Transform relies of the bin of acculumated pixel being distinct, e.g. a direct contrast between a pixel and its surrounding neighbours or if using a mask region a pixel region and its surrounds regions. WebThe Hough transform is commonly used for detecting linear features within an image. A line is mapped to a peak within parameter space corresponding to the parameters of the line. By analysing the shape of the peak, or peak locus, within parameter space, it is possible to also use the line Hough transform to detect or analyse arbitrary (non … aws クラウドプラクティショナー 試験 https://philqmusic.com
