ABSTRACT:
A currency validator includes a currency counter, a plurality of cameras, an image processor, a comparing processor, and a threshold processor. The currency counter counts multiple currencies including a test currency. Each of the cameras is located at a unique angle from a characteristic area on the test currency. The cameras record and output multiple images of the characteristic area. The image processor crops and reduces the recorded images. The comparing processor compares the processed images with corresponding references. The comparing processor then outputs the results as error matrices. The threshold processor compares the error matrices with corresponding threshold matrices. The threshold processor then outputs a validation result for the tested currency based on the comparison.
