Abstract
The present invention discloses recognizing methods of flaky or blocky prohibited articles, explosives or drugs. Specifically, the method for recognizing flaky prohibited articles, explosives or drugs comprises steps of: (1) reading in tomogram data of an object to be inspected for one tomogram; (2) pre-processing the tomogram data; (3) splitting the pre-processed tomogram data into a plurality of regions that have similar physical properties; (4) analyzing whether each of the split regions is a flaky region; (5) determining whether the flaky region recognized in the current tomogram can be merged with the flaky region detected from the previous tomogram, so as to form a flaky target; (6) determining whether each detected flaky target is complete or finished; (7) repeating steps (1)-(6) and processing each tomogram data layer by layer, until all of the tomogram data have been processed.
