Abstract:
A method of counting sheet materials applied to a pile of sheet materials, comprising the steps of: receiving an image of the pile of sheet materials; obtaining a grayscale value of a plurality of pixels along a first image axis direction of the image to form an one dimensional first array; performing binarization of the first elements of the first array with a first threshold value to form an one dimensional second array; obtaining the number of the second elements of a first value appearing between two second elements of a second value in the second array to form a third array; dividing the elements of the third array into a first cluster and a second cluster with a second threshold value; counting the number of the third elements belonging to the first cluster and defining said number as the number of the first sheet materials.
