20080270478 | Image retrieval apparatus - This invention discloses an image retrieval apparatus. The image retrieval apparatus comprises an unlabelled image selector for selecting one or more unlabelled image(s) from an image database; and a main learner for training in each feedback round of the image retrieval, estimating relevance of images in the image database and a user's intention, and determining retrieval results, wherein the main learner makes use of the unlabelled image(s) selected by the unlabelled image selector in the estimation. In addition, the image retrieval apparatus may also include an active selector for selecting, in each feedback round and according to estimation results of the main learner, one or more unlabelled image(s) from the image database for the user to label. | 10-30-2008 |

20090040225 | Apparatus and method for three-dimensional model retrieval - The present invention relates to three-dimensional model retrieval apparatus and method. The three-dimensional model retrieval apparatus according to the present invention comprises a model normalizing unit for rotating and/or translating a three-dimensional model so that main axis directions of the three-dimensional model are consistent with coordinate axes of a system coordinate system, and barycenter of the three-dimensional model is consistent with origin of the system coordinate system; a two-dimensional image generating unit for projecting said three-dimensional model respectively in a positive direction and a negative direction of each coordinate axis of said system coordinate system to generate a plurality of two-dimensional images; a model describing unit for generating a model descriptor of the three-dimensional model from said two-dimensional images; and a retrieving unit for retrieving, based on said model descriptor, a three-dimensional model which most matches an input query from a model database. | 02-12-2009 |

20140292684 | INFORMATION PROCESSING APPARATUS AND CONTROL METHOD OF INFORMATION PROCESSING APPARATUS - An information processing apparatus causes, upon accepting a switching instruction, an event controller to switch a notification destination from a first process to a second process. The first process is run by execution of an application program that is related to a screen image currently displayed on a touch panel. The second process is run by execution of the control program. The information processing apparatus displays, upon being notified of a movement event from the event controller, the screen image at a shifted position on the touch panel. The information processing apparatus transfers, upon being notified of a first touch event from the event controller, a second touch event to the first process. The second touch event is obtained by adjusting the first touch event such that a touch position included in the first touch event is modified based on the movement vector. | 10-02-2014 |
