Patent number: 10204290Abstract: A decision tree and normalized reclassification are used to classify defects. Defect review sampling and normalization can be used for accurate Pareto ranking and defect source analysis. A defect review system, such as a broadband plasma tool, and a controller can be used to bin defects using the decision tree based on defect attributes and design attributes. Class codes are assigned to at least some of the defects in each bin. Normalized reclassification assigns a class code to any unclassified defects in a bin.

Patent number: 10102614Abstract: To allow fog removal even in a densely foggy image. A fog density calculating unit 11 calculates the fog density of an input image given, by using a separated illumination light component. A reflectance component fog removing unit 13 performs fog removal on a reflectance component calculated by a reflectance calculating unit. An illumination light component fog removing unit 14 performs fog removal on the separated illumination light component. Here, the degree of fog removal by the reflectance component fog removing unit 13 is higher than the degree of fog removal by the illumination light component fog removing unit 14. Thereby, the degree of fog removal of the reflectance component can be raised without significantly raising the level of fog removal of the illumination light component.Type: GrantFiled: December 7, 2016Date of Patent: October 16, 2018Assignee: EIZO CorporationInventor: Takashi Nakamae

Patent number: 10089713Abstract: A method for registering images aligns a fixed image with a corresponding moving image. A target image and a reference image are selected. The reference and target images are relatively low-res representations of the fixed and moving images respectively. A current image distortion map is determined that defines distortions between the target and reference images. A residual image is determined by comparing the reference image and a warped target image derived from the target image based on the current image distortion map. A residual image distortion map is determined based on transform coefficients of cosine functions fitted to the residual image. The coefficients are determined by applying a DCT to a signal formed by the residual image and image gradients of the warped target or reference image. The current image distortion map is combined with the residual image distortion map to align the fixed image and the moving image.Type: GrantFiled: March 22, 2016Date of Patent: October 2, 2018Assignee: CANON KABUSHIKI KAISHAInventor: Peter Alleine Fletcher
