What is Real-Time 2D DFT with Artifact Removal about?

This paper presents a novel FPGA-based design to calculate 2D discrete Fourier transforms with simultaneous edge artifact removal in real-time. It uses a periodic-plus-smooth decomposition algorithm optimized for FPGAs to remove artifacts while still achieving over 23 frames per second for 512x512 images. This avoids increasing computation by pre or post-processing and prevents loss of important image information.
