An Efficient FPGA Implementation of Optimized Anisotropic Diffusion Filtering of Images

Algorithm 1

Adaptive iteration algorithm.

Input: Denoised images at every iteration step of (3).

Comments: Referring (3).

(1) The differences between denoised output images at every iteration step is found out.

(2) The difference between the maximum and minimum of the difference matrix found out in

Step  () is computed at every iteration step.

(3) Steps () and () are continued until the condition shown below is met.

(4) Once the condition in Step () is met the execution is stopped which in turn stops the

number of iteration thereby making it adaptive.

(5) Display the number of iteration thus encountered and exit.
