Abstract: An optical apparatus and a near-eye display apparatus including the same are provided. The optical apparatus includes a display panel configured to form an image, a first polarization rotator configured to electrically control a light emitted from the display panel to have a first polarization state, a first ¼ wave plate configured to convert the first polarization state of a light transmitted from the first polarization rotator to a second polarization state, and an optical element group configured to display a first image having a first viewing angle and a second image having a second viewing angle that is greater than the first viewing angle based on the second polarization state of a light transmitted from the first ¼ wave plate.

Abstract: A method of performing K-means clustering by a data mining system is provided. The method includes generating a plurality of initial buckets by dividing data including a plurality of points each being expressed in coordinate information, reflecting a count noise in a number of points included in each of the initial buckets and then generating a plurality of new buckets by dividing at least one initial bucket among the initial buckets based on a first threshold and a second threshold, generating a plurality of final buckets from the plurality of initial buckets or the plurality of new buckets, generating a histogram including section information for each of the final buckets and a number of points included in each of the final buckets in which the count noise is reflected, and performing K-means clustering on the histogram based on a number of clusters.

Abstract: A method of controlling an image analysis apparatus is provided. The method includes receiving a query image; determining at least one main color distributed in the query image and a specific main color from among the at least one main color by using color information contained in the query image; dividing the query image into at least one block having a predetermined number of pixels; and determining whether each of the at least one block includes more than a predetermined percentage of a main color for comparison among the at least main color, and creating a binary spatial distribution map by digitizing the at least one block.
