20080279426 | SYSTEM AND METHOD FOR VERIFYING FACE OF USER USING LIGHT MASK - A system and method for verifying the face of a user using a light mask are provided. The system includes a facial feature extraction unit for extracting a facial feature vector from a facial image received from a camera. A non-user Gaussian Mixture Model (GMM) configuration unit generates a non-user GMM from a facial image stored in a non-user database (DB). A user GMM configuration unit generates a user GMM by applying light masks to a facial image stored in a user DB. A log-likelihood value calculation unit inputs the facial feature vector both to the non-user GMM and to the user GMM, thus calculating log-likelihood values. A user verification unit compares the calculated log-likelihood values with a predetermined threshold, thus verifying whether the received facial image is a facial image of the user. | 11-13-2008 |
20090043422 | PHOTOGRAPHING APPARATUS AND METHOD IN A ROBOT - A method and apparatus for taking a picture are provided, in which a mobile apparatus detects a current position of a mobile apparatus, moves from the current position to a predetermined position to take a picture, information about an ambient image around the mobile apparatus through the image sensor, after the movement, analyzes characteristics of the received image information, compares the analyzed characteristics with a predetermined picture-taking condition, controls the mobile apparatus for the characteristics of the image information to satisfy the predetermined picture-taking condition, if the characteristics of the image information do not satisfy the predetermined picture-taking condition, and takes a picture, if the characteristics of the image information satisfy the predetermined picture-taking condition. | 02-12-2009 |
20090051787 | APPARATUS AND METHOD FOR PHOTOGRAPHING IMAGE USING DIGITAL CAMERA CAPABLE OF PROVIDING PREVIEW IMAGES - Disclosed is an apparatus for photographing an image using a digital camera capable of providing a preview image, including: an image sensor for capturing an image of a subject; a first image signal processor for processing at least one captured image as a sequent image in order to display the captured image as a preview image on a display window and detecting a face area from the captured image; a buffer for storing the image including at least one detected face area; a capture button for capturing a still image during outputting the sequent image as the preview image on the display window; a second image signal processor for processing the captured still image using the capture button; a controller for controlling to store the captured still image and information related on the face area detected from the first image signal processor prior to the input of the capture button; and a memory for storing the processed still image together with the information related on the detected face area. | 02-26-2009 |
20100168913 | Robot and method for controlling the same - A robot and a method of controlling the same are disclosed. The robot determines a presence or absence of a non-registration object if a registered object is not present in a photographing area, obtains an object name by communicating with a user if the presence of the non-registration object is decided, and additionally registers the object name in a database. Therefore, the robot recognizes the non-registration object present in the photographing area. | 07-01-2010 |
20120121126 | METHOD AND APPARATUS FOR ESTIMATING FACE POSITION IN 3 DIMENSIONS - An apparatus and method for estimating a three-dimensional face position. The method of estimating the three-dimensional face position includes acquiring two-dimensional image information from a single camera, detecting a face region of a user from the two-dimensional image information, calculating the size of the detected face region, estimating a distance between the single camera and the user's face using the calculated size of the face region, and obtaining positional information of the user's face in a three-dimensional coordinate system using the estimated distance between the single camera and the user's face. Accordingly, it is possible to estimate the distance between the user and the single camera using the size of the face region of the user in the image information acquired by the single camera so as to acquire the three-dimensional position coordinates of the user. | 05-17-2012 |
20130201158 | MULTI-TOUCH RECOGNITION APPARATUS AND CONTROL METHOD THEREOF - Disclosed herein are a multi-touch recognition apparatus and a control method thereof. The multi-touch recognition apparatus executes blur filtering for noise removal when an image is input through a camera unit photographing a screen of a display panel supporting multi-touch, calculates and outputs a difference image obtained by removing the background image stored in the storage unit from the blur-filtered image, calculates a new background image using the difference image and a binary image of the difference image, and updates the background image stored in the storage unit using the calculated new background image, thereby effectively removing a background other than multi-touch and thus improving multi-touch recognition performance. | 08-08-2013 |
