DENOISING AND/OR ZOOMING OF INSPECTION IMAGES |
摘要 |
In one aspect, there is provided a method of denoising one or more inspection images comprising a plurality of pixels, comprising: receiving an inspection image generated by an inspection system configured to inspect one or more containers, the inspection image being corrupted by a Poisson- Gaussian noise and a variance of the noise being non-constant in the plurality of pixels, and denoising the received inspection image by applying, to the inspection image, a variance-stabilizing transformation for transforming the variance of the noise into a constant variance in the plurality of pixels, wherein the variance-stabilizing transformation is based on a descriptor associated with the angular divergence of the inspection radiation and the Poisson-Gaussian noise. |
