20120236287 | EXTERNAL ENVIRONMENT VISUALIZATION APPARATUS AND METHOD - The present invention adjusts images received from plural cameras that are oriented to plural directions and combines the images with distance information. Thereafter, the circumstantial environment is visualized based on a moving object using an augmented reality technique to provide to a user. Specifically, the present invention adjusts images in plural directions and adds the distance information to improve the accuracy and uses a visualization method that displays the images with respect to the moving object. | 09-20-2012 |
20130083965 | APPARATUS AND METHOD FOR DETECTING OBJECT IN IMAGE - An apparatus and method detects an object in an original image captured by an image capturing device. The apparatus and method detects a location of the object using a thermal image for the captured image, designates a region of the detected object as an image inpainting region, restores a region corresponding to the region of the detected object using its surrounding information, examines a difference between the restored image and the original image, and separates an object region from the original image, thereby more accurately detecting the object. | 04-04-2013 |
20130202210 | METHOD FOR HUMAN ACTIVITY PREDICTION FROM STREAMING VIDEOS - A method for human activity prediction from streaming videos includes extracting space-time local features from video streams containing video information related to human activities; and clustering the extracted space-time local features into multiple visual words based on the appearance of the features. Further, the method for the human activity prediction includes computing an activity likelihood value by modeling each activity as an integral histogram of the visual words; and predicting the human activity based on the computed activity likelihood value. | 08-08-2013 |
20130287250 | METHOD AND APPARATUS FOR TRACKING OBJECT IN IMAGE DATA, AND STORAGE MEDIUM STORING THE SAME - Disclosed is a system for tracking an object in an image. A method for tracking an object in an image according to an exemplary embodiment of the present invention includes generating an object model represented by multiple patch histograms of an object that is divided into N partial patch regions and histograms are built from each patch region, forming an object model; estimating the probability of each image pixel being an object pixel; and determining the most promising location of an object in the image by using the estimated object probability values. According to the exemplary embodiment of the present invention, it is possible to more improve separability from a background than a case in which a single histogram mode is used, to increase tracking performance, and to more accurately search the object region than a mean-shift method of the related art. | 10-31-2013 |
