Cameras and image processing techniques are applied to the problem of spill detection. Fixed background data may be removed using a technique based on image subtraction. The remainder of one or more images may be segmented. The segments may then be tested to identify and remove from further analysis segments corresponding to non-spill foreground objects, for example by forming luminance and/or chr...

An imaging system and method enables 3-D direct segmentation from a series of spatially offset 2-D image slices in a volume scan. The algorithm first smoothes and preserves the interface edges of the image volume using Bottom-Hat gray scale morphological transform followed by 3-D segmentation using fast 3-D level sets by preserving topology constraints, for example, cortical thickness in a brain v...

A method of collating and using captured semiconductor-wafer image data in an automated defect analysis. The method includes the steps of receiving image data and, if necessary, converting it to a digital format. Once the data is in pixel-by-pixel form, each pixel is assigned a slope value derived from the direction of the structure edge, if any, on which it lies. The pixel-slope data is then eval...

An image alignment method and system for aligning two digital images which were intended to be scanned from the same portion of medium, but which may be skewed somewhat. A portion of the first digital image is selected as the target region and a portion of the second digital image is selected as a variable or movable region. Data from the two regions can be subjected to a mathematical or statistic...
