Pattern recognition

A computer program product, the computer program product comprising one or more computer readable storage media having program instructions collectively stored on the one or more computer readable storage media, the program instructions executable to:

• identify classes and relationships between classes in a software program code based on stored rules;
• generate a diagram image based on stored image rules and the classes and relationships between classes in the software program code, the diagram image including graphical notations and text-based information regarding the software program code;
• remove the text-based information from the diagram image to produce a modified diagram image to facilitate accurate computer-implemented image object detection;
• accessing, by the computing device, a store of template images of patterns;
• analyzing the modified diagram image using the computer-implemented image object detection to determine that the modified diagram image includes at least one predetermined pattern from the store of template images of patterns based on matching an image of a pattern of graphical notations in the modified diagram image with at least one image of a pattern of graphical notations in the at least one predetermined pattern;
• and
• generate a report including information regarding the at least one predetermined pattern;
• wherein the store of template images of patterns comprises software design patterns, and the analyzing the modified diagram image using the computer-implemented image object detection utilizes edge matching techniques to detect edges in the modified diagram image and match the edges of the modified diagram image with edges of the at least one predetermined pattern from the software design patterns.

A system comprising:

• a processor, a computer readable memory, and a computer readable storage medium;
• program instructions to identify elements and relationships between elements in a digital data product based on stored rules;
• program instructions to generate a diagram image based on stored image rules and the identified elements and relationships between elements in the digital data product, the diagram image including graphical notations and text-based information representing the elements and the relationships between the elements;
• program instructions to remove the text-based information from the diagram image to produce a modified diagram image to facilitate accurate computer-implemented image object detection;
• program instructions to analyze the modified diagram image using the computer-implemented image object detection to determine, by comparing objects in the modified diagram image to objects in a plurality of stored patterns, that the modified diagram image includes at least one predetermined pattern from the plurality of stored patterns;
• and
• program instructions to generate a report including information regarding the at least one predetermined pattern,
• wherein the program instructions are stored on the computer readable storage medium for execution by the processor via the computer readable memory;
• and
• wherein the digital data product comprises program code, the plurality of stored patterns comprises software design patterns, and the analyzing the modified diagram image using computer-implemented image object detection utilizes edge matching techniques to detect edges in the modified diagram image and match the edges of the modified diagram image with edges of the at least one predetermined pattern from the plurality of stored patterns.
