A Graph-Based Concept for Spatiotemporal Information in Cognitive Vision
نویسندگان
چکیده
A concept relating story-board description of video sequences with spatio-temporal hierarchies build by local contraction processes of spatio-temporal relations is presented. Object trajectories are curves in which their ends and junctions are identified. Junction points happen when two (or more) trajectories touch or cross each other, which we interpret as the “interaction” of two objects. Trajectory connections are interpreted as the high level descriptions. 1Supported by the Austrian Science Fund under grant FSP-S9103-N04.

Graph-based Visual Saliency Model using Background Color
Visual saliency is a cognitive psychology concept that makes some stimuli of a scene stand out relative to their neighbors and attract our attention. Computing visual saliency is a topic of recent interest. Here, we propose a graph-based method for saliency detection, which contains three stages: pre-processing, initial saliency detection and final saliency detection. The initial saliency map i...
متن کاملIdentification of mild cognitive impairment disease using brain functional connectivity and graph analysis in fMRI data
Background: Early diagnosis of patients in the early stages of Alzheimer's, known as mild cognitive impairment, is of great importance in the treatment of this disease. If a patient can be diagnosed at this stage, it is possible to treat or delay Alzheimer's disease. Resting-state functional magnetic resonance imaging (fMRI) is very common in the process of diagnosing Alzheimer's disease. In th...
متن کاملSimilarity measurement for describe user images in social media
Online social networks like Instagram are places for communication. Also, these media produce rich metadata which are useful for further analysis in many fields including health and cognitive science. Many researchers are using these metadata like hashtags, images, etc. to detect patterns of user activities. However, there are several serious ambiguities like how much reliable are these informa...
متن کاملEffect of Dual-Tasking on Variability of Spatiotemporal Parameters in Subjects with and without Anterior Cruciate Ligament Deficiency Using Linear Dynamics
Purpose: The present study aimed to determine the effect of dual-tasking on spatiotemporal characteristics in subjects with and without Anterior Cruciate Ligament Deficiency (ACLD) using linear dynamics. Methods: In this mixed model design study, spatiotemporal parameters were measured in 22 patients with ACLD (25.95±4.69 y) and 22 control subjects (24.32±3.37 y) while they were walking w...
متن کاملContent Evaluation of Iranian EFL Textbook Vision 1 Based on Bloom’s Revised Taxonomy of Cognitive Domain
Textbooks are considered as the common features of the classrooms and are important means to make contributions to curricula. Therefore, their contents are very essential to develop the adequate curriculum planning. A textbook analysis is a means by which different features of the textbooks can be analyzed and hence their effectiveness is validated. This study set out to evaluate the content of...
