Profiled component has some structural features, such as thin wall, small diameter and corner angle on inner wall. These features make it very difficult to detect the profiled component with ultrasound method, and the waves reflected from the inside arris have badly interfered the identification of echo signal. The ultrasonic creeping wave is used to detect the profiled component. In order to eliminate...
Based on the detecting corner information of the tower image, according to the feature of the front-view tower image satisfying the left-right symmetry of the building area approximately, an algorithm calculating the medial axis of the tower area is proposed. On the basis of the morphology feature of the tower and knowing the medial axis, the corresponding algorithm is presented to locate the tower...
Facial expression recognition is one of the most popular topics in emotion analysis. Most facial expression recognition systems are implemented by general expression models. Since facial expressions may be expressed differently by different people, inaccurate results are unavoidable. The proposed facial expression recognition system recognizes facial expressions using facial features of the individual...
Based on the research of the feature analysis on the X-ray films of chest and the rib, the author raised an algorithm, which realizes the automatic extraction of the rib frame by the physic regulations. This algorithm makes full use of the image processing method of filtering, edge detection, tracking seed, parabolic fitting, and some other related image processing technology, combined with the biological...
