This paper describes on a vision system for IC wafer street detection. The system uses a direct method for extracting the straight lines. The system differentiate the input image and extract straight lines which will correspond to both sides of the street of IC wafer. The straight line extraction is done not by a transform method but by a direct method. The system is implemented in a dicing machine. The features of the system are the gray level image processing, feature extraction, and learning functions.
In order to obtain three-dimensional ultrasound images such as a heart, the scanner with easy operation is required. This paper describes on a three-dimensional cardiac imaging method with motion based on the orthogonal sectional images (2-D echocardiograms). Cardiac volume is also evaluated based on these three-dimensional data. These original sectional images may be taken by transesophageal approach using two miniature phased array transducers mounted on the tip of a gastroscope or simultaneousbi-frequency method using two mechanical scanning transducers set on the thorax. Images are recorded on video tapes.
The Human Leucocyte Antigen (HLA) is under notice for its application to organic interplantation, but its inspection under the microscope is a skilled work. This paper presents an automatic inspecting system for HLA which works in real-time. We propose a new counting algorism of image components which is implimented on the system.
