Abstract: A digital image processing apparatus for easily obtaining information regarding a face, a method of controlling the same, and a recording medium for storing a program for executing the method. The digital image processing apparatus includes a face recognition unit recognizing a face from an image, a face index assignment unit assigning a face index to the recognized face if the face recognized from the image is not a previously recognized face, and a relation index update unit that, if the image includes a second face, updates a relation index corresponding to the number of times the first face and second face appear together in a plurality of images.

Abstract: The disclosed terrain model is a generative, probabilistic approach to modeling terrain that exploits the 3D spatial structure inherent in outdoor domains and an array of noisy but abundant sensor data to simultaneously estimate ground height, vegetation height and classify obstacles and other areas of interest, even in dense non-penetrable vegetation. Joint inference of ground height, class height and class identity over the whole model results in more accurate estimation of each quantity. Vertical spatial constraints are imposed on voxels within a column via a hidden semi-Markov model. Horizontal spatial constraints are enforced on neighboring columns of voxels via two interacting Markov random fields and a latent variable. Because of the rules governing abstracts, this abstract should not be used to construe the claims.

Abstract: Certain embodiments of the present invention provide for a system and method for modeling S-distortion in an image intensifier. In an embodiment, the method may include identifying a reference coordinate on an input screen of the image intensifier. The method also includes computing a set of charged particle velocity vectors. The method also includes computing a set of magnetic field vectors. The method also includes computing the force exerted on the charged particle in an image intensifier. Certain embodiments of the present invention include an iterative method for calibrating an image acquisition system with an analytic S-distortion model. In an embodiment, the method may include comparing the difference between the measured fiducial shadow positions and the model fiducial positions with a threshold value. If the difference is less than the threshold value, the optical distortion parameters are used for linearizing the set of acquired images.

Abstract: Systems and methods for determining an inconsistency characteristic of a composite structure, such as inconsistency density-per-unit area. In one implementation, a method is disclosed for determining an inconsistency characteristic of a composite structure. The method involves determining a first distance from a first reference point of the composite structure to an inconsistency; determining a second distance from a second reference point of the composite structure to the inconsistency; using the first and second distances to establish a reference area of the composite structure; and considering each inconsistency detected within the reference area and producing therefrom an inconsistency characteristic representative of the composite structure.

Abstract: The detection of red-eye defects is enhanced in digital images for embedded image acquisition and processing systems. A two-stage redeye filtering system includes a speed optimized filter that performs initial segmentation of candidate redeye regions and optionally applies a speed-optimized set of falsing/verification filters to determine a first set of confirmed redeye regions for correction. Some of the candidate regions which are rejected during the first stage are recorded and re-analyzed during a second stage by an alternative set of analysis-optimized filters to determine a second set of confirmed redeye regions.

Abstract: Aspects of a method and system for change detection in localization and tracking of objects in a smart video camera are provided. A programmable surveillance video camera comprises processors for detecting objects in a video signal based on an object mask. The processors may generate a textual representation of the video signal by utilizing a description language to indicate characteristics of the detected objects, such as shape, texture, color, and/or motion, for example. The object mask may be based on a detection field value generated for each pixel in the video signal by comparing a first observation field and a second observation field associated with each of the pixels. The first observation field may be based on a difference between an input video signal value and an estimated background value while the second observation field may be based on a temporal difference between first observation fields.

The system is configured to receive a time period and a parameter concerning an entity, retrieve an event which is related to the entity and occurred within the time period from events which are previously extracted automatically from unstructured text, and display an indication of the event superimposed on a display representing the time series of the parameter for the time period.

Abstract: A biometrical feature inputting apparatus includes a 1-dimensional or quasi 1-dimensional image sensor. When a finger and the image sensor are relatively slid, a finger sliding guide keeps a finger and an effective pixel unit of the image sensor to a constant distance without any contact between them. An image processing section sequentially generates partial images by imaging emission light that is scattered inside the finger and then emitted from a skin surface of the finger by the image sensor during the relative motion of the finger and the image sensor and link the partial images to an image.
