WebApr 25, 2024 · Shifan Zuo, Xuelei Chen. We present a simple and fast method for incoherent dedispersion and fast radio burst (FRB) detection based on the Hough transform, which is widely used for feature extraction in image analysis. The Hough transform maps a point in the time-frequency data to a straight line in the parameter space, and points on the same ...
