Abstract

The invention discloses a method and a relevant device to eliminate image contour noise points, which are beneficial to solve the problem in the prior art that a currently available financial device is often interfered by noises when it processes images. The method comprises: acquiring the contour points of an image; obtaining a contour point set A; removing some discrete value from the set A; obtaining a contour set B; and using the contour points in set B for Hoff straight line fitting to determine the image contour.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and a related device for removing noise points in an image outline. Background technique [0002] Financial equipment such as automatic cash deposit and withdrawal machines of financial institutions such as banks usually include a banknote detector, which uses image processing technology to identify banknotes. [0003] Due to the influence of the environment where the banknote detector is located, such as temperature, dust and electromagnetic interference, noise interference will inevitably be introduced into the image data collected by the banknote detector, and these noise interference data will likely cause the image to fail to be processed or cannot be handled correctly. Contents of the invention [0004] Embodiments of the present invention provide a method and a related device for removing noise points in an image outline, so as to help solve the proble...
