A Correlation Based Strategy for the Acceleration of Nonlocal Means Filtering Algorithm

A Correlation Based Strategy for the Acceleration of Nonlocal Means Filtering Algorithm

Although the nonlocal means (NLM) algorithm takes a significant step forward in image filtering field, it suffers from a high computational complexity. To deal with this drawback, this paper proposes an acceleration strategy based on a correlation operation. Instead of per-pixel processing, this app...
