Abstract
A method for a deconvolution of a digital input image (I(x)) having a plurality of input voxels (x), in particular a digital input image obtained from a medical observation device, such as a microscope or endoscope and/or using fluorescence, includes computing a local signal-to-noise ratio (SNR(x)) within an input region (R(x)) of the digital input image, the input region consisting of a subset of the plurality of input voxels of the digital input image and surrounding the current input voxel. A noise component (β(SNR)) is computed from the local signal-to-noise ratio, the noise component representing image noise (([h*f](x), n(x)) in the deconvolution. The noise component is limited to a predetermined minimum noise value (β) for a local signal-to-noise ratio above a predetermined upper SNR threshold value (SNR) and is limited to a predetermined maximum noise value (β) for a local signal-to-noise ratio below a predetermined lower SNR threshold value (SNR).
