  • Patent number: 8345042
    Abstract: A retrieval method targeted for partial characteristic shapes existing in a polyhedral shape is provided. The method converts inputted shape model data into triangular mesh data, extracts and classifies triangular mesh data groups that form the partial characteristic shapes. The method calculates the characteristic amount of the triangular mesh data groups that represent the classified partial characteristic shapes and then calculates the difference between the characteristic amount of the triangular mesh data groups and the characteristic amount of a query shape to display a partial characteristic shape that has a small difference in the characteristic amount or the query shape. Furthermore, the method displays a list of candidates for similar shapes based on the difference value of the characteristic amount.

  • Patent number: 8340395
    Abstract: The invention relates to a defect inspection apparatus in which images of mutually corresponding areas in identically formed patterns on a sample are compared to detect mismatched portions of the images as defects. The defect inspection apparatus includes an image comparator that creates a feature space with the use of feature quantities calculated from pixels of images acquired under different optical conditions and detects outlier values in the feature space as defects. Thus, the defect inspection apparatus can detect various defects with high sensitivity even if there are luminance differences between images of identical patterns which are attributable to the difference in wafer pattern thickness.
