For nonlinear problem in target tracking, on the basis of maneuver turn model, the AGIMMCKF-algorithm is proposed, which is a variable multiple model algorithm that combined cubature kalman filter (CKF) with adaptive grid (AG). CKF as a filter, the algorithm using grid center and the adjustment of the minimum distance between grid to change turn model set adaptively so as to effectively track targets,...
In the biomedicine domain, a large number of papers are published every day, which is crucial to search for the relevant answers for the user's query. However, documents are not exactly what the users want. Instead, snippets, small segments from the documents, are more proper to meet the requirement of the users. Hence, this paper proposes a biomedical snippet retrieval framework to exactly locate...
Both Vague sets theory and Fuzzy sets theory were often used to handle fuzzy information. The two theories had their own merits and demerits. Using fuzzy sets theory, the nonlinear mapping relationship of the fuzzy system could be depicted much better by changing (except ?? = 1 and p = 1, which become linear model) ?? (optimization criterion parameter) and p (distance parameter), although only two...
Images elicit a variety of emotional responses related to image content, overall aesthetic appeal, or a combination of both. One aspect of aesthetic appeal is harmony: the pleasing or congruent arrangement of parts producing internal calm or tranquility. We conducted a series of experiments to identify what low level features could predict harmony in an image. Subjective judgments of image harmony...
Background subtraction has been widely used in many intelligent video surveillance systems. It uses a background model to achieve target recognition by removing the background pixels of video images. Because of some very strong noises, the method is often hard to work well. For this reason, this paper proposes a novel background subtraction based on regional Gaussian model. Firstly, a modified region...
