High Throughput VLSI Architecture for Bilateral Filtering in Computer Vision

A real time hardware design for bilateral filtering

“…In [7], a bilateral grid with variable-sized windows was implemented by introducing a window radius parameter, effectively restraining the growth of hardware resources as the window size increases. A novel solution that facilitates intra image content-adaptive bilateral filtering by modulating range and space sigma through virtual sub-tables was proposed in [8]. This approach reduced both hardware design complexity and performance impact on the original algorithm to a negligible extent.…”
