摘要: A system for identifying a repair cut location for a defect in a liquid crystal device includes receiving an input image, a defect mask image, and a landmark structure image. The system determines a repair cut location, based upon the input image, the defect mask image, and the landmark structure image, for a liquid crystal device proximate the defect. The determination may be based upon a type of said defect, a cause of said defect, a position of said defect, and a spatial relationship of the defect and a structure of the landmark image.

摘要: A system for detecting newton ring mura on a display includes sensing an image of the display with an image capture device and determining a border boundary of an illuminated portion of the display. The image is spatially filtered as defined by the border boundary using a filter that reduces sensor noise and a grid pattern of the display. The spatially filtered image is processed to determine if a region proximate a pixel location is a potential newton ring mura defect and characterizing the potential newton ring mura defects to remove at least one of the potential newton ring mura defects.

摘要: An electronic device configured for defect detection is described. The electronic device includes a processor and instructions stored in memory that is in electronic communication with the processor. The electronic device performs background suppression on the image data based on a transform of the image data to obtain a score map. The electronic device also applies thresholding to the score map to generate a detection mask. The thresholding comprises bi-thresholding. The electronic device additionally detects any defects based on the detection mask. The electronic device further indicates any defects.

摘要: A method for image processing that includes determining edge pixels of a model image using an edge based technique, and an angular orientation for each of the edge pixels of the model image. The method determines a lower spatial resolution model image based upon the model image and determining respective angular orientations for the lower spatial resolution model image. The method determines edge pixels of an input image using an edge based technique, and an angular orientation for each of the edge pixels of the input image. The method determines a lower spatial resolution input image based upon the input image and determining respective angular orientations for the lower spatial resolution input image. The method matches the lower spatial resolution model image with the lower spatial resolution input image to determine candidate locations of an object within the input image and based upon the candidate locations matching the input image with the model image.
