Due to the complexities of the image processing algorithms, correcting spatial distortion of optical images quickly and efficiently is a major challenge. This paper describes an efficient pipelined parallel architecture for optical distortion correction in imaging systems using a low cost FPGA device. The proposed architecture produces a fast, almost realtime solution for the correction of image distortion...
Fast and efficient operation is a major challenge for complex image processing algorithms executed in hardware. This paper describes novel algorithms for correcting optical geometric distortion in imaging systems, together with the architectures used to implement them in FPGA-based hardware. The proposed architecture produces a fast, almost real-time solution for the correction of image distortion...
A novel algorithm for correcting optical spatial distortion in imaging systems is presented, together with the architectures implemented for FPGA-based hardware. Since coordinate transformation functions generally require square root and trigonometric functions, which are not easily calculated using FPGA hardware, the CORDIC (coordinate rotation digital computer) algorithms are employed for these...
