WebFeb 9, 2024 · As an efficient feature extraction technology, Hough transformation is also very helpful to solve the problem of crack identification. ... In the Hough space … WebThe circle Hough Transform (CHT) is a basic feature extraction technique used in digital image processing for detecting circles in imperfect images. The circle candidates are produced by “voting” in the Hough parameter space and then selecting local maxima in an accumulator matrix. It is a specialization of the Hough transform .
