An Efficient FPGA Implementation of Optimized Anisotropic Diffusion Filtering of Images

Table 1

Runtime comparison between acceleration rates of our proposed hardware implementation of anisotropic diffusion filter for different image resolutions.

Image; resolution	Software execution; time (seconds)	Hardware execution; time (seconds)	Accelerate; rate
150 × 150	0.101	0.0011	(0.101/0.0011) = 91
512 × 512	0.402	0.0131	(0.402/0.0131) = 30
