Abstract: A cell-to-cell comparison method for inspecting a defect in a subject in which unit cells that may be expressed by a two-dimensional (2D) vector are periodically arranged according to an embodiment of the present invention includes: obtaining an image of the subject including an array of the unit cells; generating a tile that is a set of pixels corresponding to the same position in a plurality of unit cells within the array in the image; determining a gray level of each of a plurality of pixels within the tile; and determining whether the plurality of pixels within the tile are defective on the basis of the determined gray level of each of the plurality of pixels.

Abstract: A method of adding a virtual insertion to an image, according to an embodiment, includes extracting dynamic features from an input image, associating the dynamic extracted features with dynamic reference features in a reference feature database, generating a camera model based on the associations, mixing a virtual insertion into the input image based on the camera model, and outputting an image containing both the input image and the virtual insertion. According to another embodiment, a method of adding a virtual insertion to an image includes generating a biased camera model using a statistically selected subset of a plurality of non-fixed regions of the image, locating fixed reference objects in the image using the biased camera model as an entry point for a search, generating a corrected camera model using the fixed reference objects in the image, and adding a virtual insertion to the image using the corrected camera model.
