Abstract
This paper describes a model of digital filtering of noisy contrasting images with minimum blur of brightness at the edge of the drop, which is based on smoothing out digital images with the help of generalized method of least modules. The model presupposes variation of two parameters of the loss function as a function on the degree of contrast and noise level. The results are based on extensive computational experiments performed by the method of Monte Carlo statistical tests.
