摘要：
The Radon transform (RT) is a widely studied algorithm used to perform image pattern extraction in fields such as computer graphics, medical imagery, and avionics. Real-time implementation of the discrete RT (DRT) is extremely difficult due to its use of complex trigonometric functions and O(N-3) time complexity, making its use in video applications difficult. A O(N(2)lgN) approximate discrete (ADRT) has been presented in literature [1] that allows highly parallel computation. This paper presents an architecture that uses the ADRT to create a computation architecture known as the xADRT Performance analysis indicates that it can achieve a refresh rate of 10 frames per second for use in real-time image processing applications.
