Solution of the recognition problem of various objects in images is usually difficult be-
cause of the presence of various kinds of distortions. This paper describes a method of
pretreatment of images using bilateral and shock filters for subsequent pattern recogni-
tion method of contour analysis. Assessment of the recognition quality, when using these
filters, and without filters for different parameters is made
.
Keywords:
pattern recognition, image processing, bilateral filter, shock filter, contour
analysis
