<p>An image-recognition method (500) for identifying items in a bookbinding machine is proposed. The method includes the steps of: acquiring (506) a digital representation of at least one sample image to be learned, the representation being composed of a plurality of elements grouped into blocks, calculating (508) at least one parameter for each block of the sample image, the at least one parameter being based on a portion of the representation corresponding to the block, determining (512-520) at least one threshold value for each block of the sample image according to a comparison between the at least one parameter of the block and the parameters of adjacent blocks, acquiring (530) the digital representation of a current image to be verified, calculating (556) the at least one parameter for each block of the current image, and verifying (558-566) a match of the current image with an expected sample image according to a criterion based on a comparison between the parameters of the current image and the parameters of the expected sample image depending on the corresponding threshold values.</p> |
