Abstract EN
This paper proposes a novel iterative two-stage method to suppress salt and pepper noise.
In the first phase, a multilevel weighted graphs model for image representation is built to characterize the gray or color difference between the pixels and their neighbouring pixels at different scales.
Then the noise detection is cast into finding the node with minimum node strength in the graphs.
In the second phase, we develop a method to determine the order-inducing variables and weighted vectors of the induced generalized order weighted average (IGOWA) operator to restore the detected noise candidate.
In the proposed method, the two stages are not separate, but rather alternate.
Simulated experiments on gray and color images demonstrate that the proposed method can remove the noise effectively and keep the image details well in comparison to other state-of-the-art methods.
