Vortex detection of flow field based on pattern matching;

The system can automatically inspect and recognize characters of piston surface by properly image processing and analyzing technology such as pattern matching , image calibration, image extraction, threshold segmentation, morphology, optical character recognition and so forth.

According to adopt the two stages pattern match method, improving the recognition speed and accuracy with wiping off the error points in global pattern match by using area analysis method.

The pattern match and recognition for weld image were realized by using the sub-VI in Labview and the combination of the traditional pattern match technology and the edge information of the weld.

A method of combining facial geometric characteristics,correlation pattern match,and improved integral projection was presented to implement an expeditious and effective way to detect eyes.
