Curved object location by Hough transformations and inversions

摘要

A new technique using the straight-line Hough transform is advanced for locating curved objects or target tracks in a 2-D image. Generalized Hough transforms to achieve this are computationally expensive. Our proposed technique involves thresholding the Hough space and performing transformations and an inverse Hough transform. Peaks in this final inverse space provide curved object identification and determination of the parameters of each curved object. A theoretical development and initial simulation results are provided.
