摘要： A method and apparatus for deriving a representation of an image is described. The method involves processing signals corresponding to the image. A two-dimensional function of the image, such as a Trace transform (T (d, ϑ)), of the image using at least one functional T, is derived and processed using a mask function (β) to derive an intermediate representation of the image, corresponding to a one-dimensional function. In one embodiment, the mask function defines pairs of image bands of the Trace transform in the Trace domain. The representation of the image may be derived by applying existing techniques to the derived one-dimensional function.

摘要： A method of measuring occluded features in machine vision metrology. The method allows for high precision measurement of features that are partially obscured by an extraneous object (e.g., an overlay grid of a flat panel display screen mask). The method first roughly locates the edge points of the feature to measure. In one embodiment, the rough edge location is performed by using morphology filters to delete the extraneous object (e.g., the grid) and then doing edge detection on the filtered image. Once the rough edge locations are determined, the method then returns to the original unaltered image and for each of the roughly located edge points does edge detection in a close neighborhood of the point in the original unaltered image. These refined edge points are then used to fit the feature for highly precise measurements.

摘要： The method of analyzing an object contour image (100), useful for fast object detection based on contour matching comprises: specifying a scan path (306) of positions (xR, yR) in the contour image (100) of a region of interest (303), for processing substantially all pixels of contour image (100); constructing a first table (111) containing for each pixel in the contour image (100) of non-zero value at least one position coordinate (x); constructing a fourth table (311) corresponding to a position of the region of interest (303), containing at least for each parallel line of pixels traversing the region of interest (303), an index (312) of an entry (121) in the first table (111), of, given a scan direction, the first non zero pixel of the contour image (100) lying on the respective parallel line and being inside the region of interest (303); and constructing a fifth table (313) corresponding to a position of the region of interest (303), containing at least for each parallel line of pixels traversing the region of interest (303), an index (314) of an entry (121) in the first table (111), of, given the scan direction, the last non zero pixel of the contour image (100) lying on the respective parallel line and being inside the region of interest (303).
