Speckle denoising in digital holography by nonlocal means filtering Academic Article uri icon

abstract

  • We demonstrate the effectiveness of the nonlocal means (NLM) filter for speckle denoising in digital holography. The speckle noise adapted version of the NLM filter is compared with other common speckle denoising filters and is found to give better visual and quantitative results.
