A computer-implemented method of denoising one or more inspection images comprising a plurality of pixels , comprising: receiving (S1) an inspection image generated by an inspection system configured to inspect one or more containers , wherein the inspection system is configured to inspect the container by transmission, through the container, of inspection radiation , the inspection radiation having an angular divergence divergent from a focal point of an inspection radiation source to an inspection radiation receiver comprising a plurality of detectors , the detectors being adjacent to one another to form a straight line array of detectors and being associated with the pixels in the inspection image , each detector being capable of receiving an individual angular sector of the inspection radiation , and the inspection image is corrupted by a Poisson-Gaussian noise and a variance of the noise being non-constant in the plurality of pixels ; and denoising (S2) 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 individual angular sector of the inspection radiation and the Poisson-Gaussian noise, the descriptor being associated with each pixel of the plurality of pixels of the inspection image . receiving (S1) an inspection image generated by an inspection system configured to inspect one or more containers , wherein the inspection system is configured to inspect the container by transmission, through the container, of inspection radiation , the inspection radiation having an angular divergence divergent from a focal point of an inspection radiation source to an inspection radiation receiver comprising a plurality of detectors , the detectors being adjacent to one another to form a straight line array of detectors and being associated with the pixels in the inspection image , each detector being capable of receiving an individual angular sector of the inspection radiation , and the inspection image is corrupted by a Poisson-Gaussian noise and a variance of the noise being non-constant in the plurality of pixels ; and the inspection system is configured to inspect the container by transmission, through the container, of inspection radiation , the inspection radiation having an angular divergence divergent from a focal point of an inspection radiation source to an inspection radiation receiver comprising a plurality of detectors , the detectors being adjacent to one another to form a straight line array of detectors and being associated with the pixels in the inspection image , each detector being capable of receiving an individual angular sector of the inspection radiation , and the inspection image is corrupted by a Poisson-Gaussian noise and a variance of the noise being non-constant in the plurality of pixels ; and denoising (S2) 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 individual angular sector of the inspection radiation and the Poisson-Gaussian noise, the descriptor being associated with each pixel of the plurality of pixels of the inspection image . <EOS>
