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

abstract

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