HoughTransform2 5.3 Generalized Hough Transform In this class, we willl learn about generalized Hough Transform. ● Hough Circles Let's find circles by Hough Transform. Equation of circle is If radius is known, we should consider 2D Hough space and Accumulator array would be A(a, b). A point in 2D space becomes a circle in Hough space. More points become more circles. If radius is not known, we should consider 3D Hough space. In this case, the.. 2020. 8. 7. 5.2 Hough Transform In this class, we will learn about Hough Transform. How do we find image boundaries (lines)? ● Hough Transform - Hough Transform is a generic framework for detecting a shape/object. - Edges don't have to be connected. - Lines can be occluded. - The key idea is 'Democratic' Detector. → Each image edge votes for the possible line model. ● Image and parameter space We can see the image as parameter.. 2020. 8. 5. 이전 1 다음
