The data verification workstation is configured to obtain document images from the image server, present portions of document images to an operator, wherein the document images include text, and receive input from the operator based on the text. The input includes data elements. The data verification workstation is also configured to acquire machine-recognized data elements from the data entry server. The machine-recognized data elements were acquired from the document image during a machine-implemented data acquisition process based on the text. The data verification workstation is also configured to compare the data elements received from the operator to the machine-recognized data elements and selectively prompt the operator to re-input the data elements based on the comparison. | 2010-06-03 |
20100135580 | METHOD FOR ADJUSTING VIDEO FRAME - A method for adjusting a face area of a user in the video frame captured by a camera lens is disclosed. In the method, an edge of an image in the video frame is detected, wherein the image contains a face area representing a face of a user. Then, a plurality of facial features of the face are extracted from the face area according to the image edge. Then, a facial feature database is referred to for the facial features to estimate a tilt angle between a plane corresponding to the face of the user and a focusing direction of the camera lens towards the face on capturing the video frame. Finally, the estimated tilt angle is used for adjusting relative proportion between image parts in the face area. As a result, the video frame displaying an image effect of the face as seen by a person from a position in front of and level with the face and having no tilted image of the face is obtained. | 2010-06-03 |
20100135581 | Depth estimation apparatus and method - A depth estimation apparatus is provided. The depth estimation apparatus may estimate a depth value of at least one pixel composing an input video based on feature information about at least one feature of the input video, a position of the at least one pixel, and a depth relationship among the at least one pixel and neighboring pixels. | 2010-06-03 |
20100135582 | SYSTEM AND METHOD FOR SEARCH PORTIONS OF OBJECTS IN IMAGES AND FEATURES THEREOF - Embodiments enable searching of portions of objects in images, including programmatically analyzing each image in a collection in order to determine image data that, for individual images in the collection, represents one or more visual characteristics of a portion of an object shown in that image. A user is enabled to specify one or more search criteria that includes image data, and a search result may be determined based on one or more images in the collection that show a corresponding object that has a portion that satisfies a threshold. The threshold is defined at least in part by the one or more search criteria. | 2010-06-03 |
20100135583 | METHOD FOR EVALUATING MOVING IMAGE RESOLUTION - Disclosed is a method for evaluating a moving image resolution capable of quantitatively evaluating a moving image resolution for a display device. The method comprises displaying a test pattern on a screen, and moving the test pattern in a predetermined direction; obtaining an image of the test pattern on the screen; removing noise from the image; detecting edge regions of the image having noise removed therefrom; emphasizing the detected edge regions; scanning the emphasized edge regions by rotating any reference line a plurality of times, the reference line passing through a center point of the emphasized edge regions; and analyzing a pattern of the scanned result, and comparing it with the original test pattern. | 2010-06-03 |
20100135584 | Image-Based Face Search - A search includes comparing a query image provided by a user to a plurality of stored images of faces stored in a stored image database, and determining a similarity of the query image to the plurality of stored images. One or more resultant images of faces, selected from among the stored images, are displayed to the user based on the determined similarity of the stored images to the query image provided by the user. The resultant images are displayed based at least in part on one or more facial features. | 2010-06-03 |
