A New Shearlet Framework for Image Denoising

open access: yesIranian Journal of Electrical and Electronic Engineering, 2016
Traditional noise removal methods like Non-Local Means create spurious boundaries inside regular zones. Visushrink removes too many coefficients and yields recovered images that are overly smoothed.

Defect Detection in Magnetic Tile Images Based on Non-subsampled Shearlet Transform

open access: yes工程科学与技术, 2017
:A novel surface defect detection method based on non-subsampled shearlet transform (NSST) was proposed for detecting defects with random noise,low contrast,uneven background and regularly distributed grinding texture in magnetic tile surface images.The ...
