Abstract:
An overlapping bill detection method and apparatus are provided. The method includes: collecting front images and back images of banknotes to be recognized, and transmission images, acquiring front banknote information and back banknote information of the banknotes to be recognized based on the front images and the back images, initializing a local feature attribute window, where the local feature attribute window is a template of a predetermined recognition region containing a feature attribute of an image to be recognized, measuring a coupling degree of the transmission images of the front images and the back images according to the local feature attribute window to obtain a measurement result, determining whether the measurement result meets a preset banknote overlapping condition, if so, determining that the banknotes to be recognized are overlapped, and otherwise, determining that the banknotes to be recognized are not overlapped

Claim (Index 2):
The method according to  claim 1 , wherein the measuring the coupling degree of the transmission images of the front images or the back images based on the local feature attribute window to obtain the measurement result comprises at least one of the following sub-steps:\n a first sub-step, comprising:\n calculating a tone texture period and a structure texture period corresponding to a region of the transmission image defined by the local feature attribute window, wherein the tone texture period comprises the number of periodical color textures, the number of periods and a length of the period, and the structure texture period comprises the number of periodical structure texture features, the number of periods and a length of the period; and \n determining whether a difference between the tone texture period and a preset standard value corresponding to the local feature attribute window exceeds a first preset threshold and whether a difference between the structure texture period and the preset standard value corresponding to the local feature attribute window exceeds the first preset threshold, to obtain a first determination result; \n a second sub-step, comprising\n acquiring a texton corresponding to the region of the transmission image defined by the local feature attribute window, wherein the texton is a texture unit having a specific shape; and \n determining whether a difference between the texton and a predetermined standard texton corresponding to the local feature attribute window exceeds a second preset threshold, to obtain a second determination result; and \n a third sub-step, comprising:\n calculating a texture definition corresponding to the region of the transmission image defined by the local feature attribute window, wherein the texture definition indicates a blurring degree of a predetermined texture; and \n determining whether a difference between the texture definition and a preset standard value corresponding to the local feature attribute window exceeds a third preset threshold, to obtain a third determination result.
