Abstract:
A complex authentication method includes identifying a user based on at least one image of a face image and a fingerprint image; identifying a first pattern associated with at least one of a feature point extracted from the face image and a first input to a display of an electronic device; and performing an operation assigned to the identified user and the identified first pattern.
Abstract:
An apparatus and corresponding method are provided to match images and include assigning depth candidate values to a pixel in a first image, and reassigning third depth candidate values to a first pixel in the first image based on first depth candidate values assigned to the first pixel and second depth candidate values assigned to a second pixel adjacent to the first pixel. The apparatus and method also include determining one of the third depth candidate values to be a depth value of the first pixel, and matching the first pixel and a third pixel in a second image corresponding to the determined depth value of the first pixel.
Abstract:
At least some example embodiments disclose a device and a method for determining a landmark of an image. The device may compare, to a key landmark set as a reference landmark, a first candidate landmark detected from a region of interest (ROI) of an input image and a second candidate landmark tracked from a previous frame, and determine a landmark similar to the key landmark to be a final landmark.
Abstract:
A facial recognition method includes identifying a first makeup pattern in a region of interest (ROI) of a first image, applying one of the first makeup pattern and a candidate makeup pattern to a ROI of a second image corresponding to the ROI of the first image to generate a third image and recognizing a face based on the first image and the third image.
Abstract:
At least one example embodiment discloses a user authentication method including acquiring representative reference images classified from a pre-stored first reference image of a user based on desired criteria, acquiring representative input images classified from a first input image based on the desired criteria, calculating a similarity between the first input image and the first reference image based on the representative input images and the representative reference images, and authenticating a user based on the calculated similarity.
