摘要： A machine-vision-based counter includes an image acquisition component (imager), wherein light provides discrimination between a background field and imageable units located away from the imager The imager outputs data representing the field and units; an image processor receiving imager data finds countable units therein. An operator interface accepts command inputs and presents count output. A controller manages image acquisition, processor, and operator interface functions. A counting method includes configuring an imager to detect light, directing light from a source to units positioned to be detected by the imager, and directing the light to the imager. The method includes discriminating between a background field and imageable units; providing, as an imager output, data representing the field and units; configuring an image-processor to receive imager data; configuring the processor to interpret the data as counted units on a background field; and configuring an operator interface to present a count result.

摘要： A method and apparatus is provided that detects extended defects in a surface, by detecting connected features and classifying the connected features so as to identify defects. A method and apparatus is described which processes an image for edges, thresholds the edge and then determines whether the edges are connected features by examining the orientation of the edges compared to their neighboring edges. Application of the method to read/write heads in a storage-drive assembly application is disclosed. Particular enhancements of the method and apparatus for that application are described, including classifying the defects on a head based on their relationship to the boundary of the head, and applying hysteresis thresholding or diffusion to identify cracks which interfere with the function of the heads.
