摘要： The present disclosure relates to a method and apparatus for searching an image, and to a computer-readable recording medium for executing the method. The apparatus for searching an image of the present disclosure obtains features of an input image; and obtains words that correspond to the features respectively and an adjacent word that is adjacent to the words corresponding to the features. When a word is assigned to a first word cell of a plurality of word cells that are included in a visual feature space, an adjacent word is assigned to at least one second word cell that is adjacent to the first word cell, where the plurality of word cells is assigned to different words, and at least one word being within a predetermined distance from a word is designated as the adjacent word. The apparatus is further configured to search for an image that is identical or similar to the input image based on information associated with a first group of images corresponding to the word and information associated with a second group of images corresponding to the adjacent word, the information on the first and second groups of images being stored in a database.

摘要： System, apparatus, method, and computer readable media for on-the-fly captured image data enhancement. An image or video stream is enhanced with a filter in concurrence with generation of the stream by a camera module. In one exemplary embodiment, HD image frames are filtered at a rate of 30 fps, or more, to enhance human skin tones with an edge-preserving smoothing filter. In embodiments, the smoothing filter is applied to an image representation of reduced resolution, reducing computational overhead of the filter. The filtered image is then upsampled and blended with a map that identifies edges to maintain an edge quality comparable to a smoothing filter applied at full resolution. A device platform including a camera module and comporting with the exemplary architecture may provide enhanced video camera functionality even at low image processing bandwidth.

摘要： According to a method for providing a notification on a face recognition environment of the present disclosure, the method includes obtaining an input image that is input in a preview state, comparing feature information for a face included in the input image with feature information for a plurality of reference images of people stored in a predetermined database to determine, in real-time, whether the input image satisfies a predetermined effective condition for photographing. The predetermined effective condition for photographing is information regarding a condition necessary for recognizing the face included in the input image at a higher accuracy level than a predetermined accuracy level. The method further includes providing a user with a predetermined feedback for photographing guidance that corresponds to whether the predetermined effective condition for photographing is satisfied. According to the method, a condition of a face image detected for face recognition is checked, and if there is an unsuitable element in recognizing the face, it is notified to a user such that an obstruction environment hindering the face recognition by the user is removed, for enhancing a success rate of the face recognition.
