The concept of the Hough transform (HT) was first proposed by Hough in 1962. In this original version of the Hough transform, the lines in the image space are represented by slope-intercept points in the parameter space.
WebNov 15, 2013 · Hough Transform • General Definition HT is a technique to extract required model features from Images and its purpose is primarily to find imperfect instances of objects within a certain class of shapes by a voting procedure. WebThe Hough transform ( / ˈ h ʌ f /) is a feature extraction technique used in image analysis, computer vision, and digital image processing.
