摘要： Systems and methods for detecting eye information are described. According to one embodiment, a detecting device includes a determination unit, a generation unit, and a detection unit. The determination unit is configured to determine whether a user wears glasses from an input image by using a first neural network including a plurality of filters. The generation unit is configured to generate a face image in which the glasses are removed from the input image by using a learned generator when a glasses-wearing signal is received from the determination unit. The detection unit is configured to generate an eye image by receiving the input image from the determination unit or receiving the face image from the generation unit and detect a pupil from the eye image using a second neural network including a plurality of filters.

摘要： A pupil detection device includes: a filter weight learner configured to generate a target image on the basis of pupil coordinate data acquired from a learning image and learn weights of a plurality of filters in order to generate a filtered image, by filtering the learning image using the plurality of filters, that is within a predetermined reference range of the target image; a split image generator configured to generate a pupil region split image for an input image using the plurality of filters having the learned weights; and a pupil coordinate detector configured to remove noise of the pupil region split image, select at least one of a plurality of pixels from which noise is removed, and detect pupil coordinates.

摘要： A method for controlling a mobile communication device using a user's distance specifying algorithm, the method comprises a first process of receiving an input image from a camera to generate first data; a second process of determining whether there is a candidate group that can be determined as a face using the first data and second data including a user's distance information; a third process of extracting, if there is a candidate group that can be determined as a face, from a plurality of third data including location information of the candidate group, fourth data having a minimum distance between a center of the first data and a center of the third data; and a fourth process of comparing the fourth data with a predetermined user's distance to determine whether it has a value within a tolerance range.

摘要： An image processing apparatus for transforming a wide-angle image into a narrow-angle image includes a deblurrer performing deblurring on the wide-angle image to generate a deblurred image; a super-resolution (SR) unit performing SR processing on the deblurred image to generate an upscaled transformed image; and a view transformer performing view transformation to obtain the narrow-angle image based on the wide-angle image and the upscaled transformed image.
