PURPOSE:To rapidly form a density co-occurrence matrix by forming an image shifted from an original image by a specified distance, forming data obtained by forming the data of respective picture elements of the original image and the data of respective picture elements of the shifted image as a series of bit string, and counting up the number of picture elements in each value of the formed data. CONSTITUTION:An image shifted from the original image by specified distance Sx, Sy is formed, data obtained by forming the data of respective picture elements of the original image and the data of respective picture elements of the shifted image as a series of bit strings are formed and the number of picture elements in each value of the formed data is counted out. In this hardware processing, the processing can be completed by one scanning after the formation of the shifted image. When the number of hierarchies is set up to (m), the processing speed becomes about (m) times the ordinary one, and generally, (m) is about 16 to 256. Thus, the density co-occurrence matrix can be rapidly formed. |
