The lifting scheme is used as a motivational tool for designing a better temporal subband scheme in video coding. The new subband coding scheme replaces the typical Haar filterbank. A simple criterion is used for the detection of scene changes in video sequences, and a modification to the Haar lifting scheme is developed that allows for adjusting the filterbank near a scene change. The new edge...

This paper investigates the influence of depth of field on change detection in both pictorial and solid scenes. In this work, a within-subjects experiment is conducted using a flicker paradigm, with which the hit rate and response time for change detection are obtained. The results show that depth of field has effects on change detection: the hit rate is smaller and response time is longer in t...

Abstract—In the coherent change detection application of repeat pass SAR interferometry (InSAR) the scene coherence is used to detect areas of man-made scene disturbance. The sensitivity of this technique however is dependent on the extent of decorrelation across the scene that arises due to processing aberrations, system noise and environmental effects. Formulating the detection problem as a h...

This work examines how context may influence the detection of changes in flickering scenes. Each scene contained two changes that were matched for low-level visual salience. One of the changes was of high interest to the meaning of the scene, and the other was of lower interest. High-interest changes were more readily detected. To further examine the effects of contextual significance, we inver...

Abstract Autism is characterized by atypical use of social communicative cues, such as another person’s gaze or point. Despite these real-world difficulties, experimental manipulations often reveal minimal group differences. One factor that may contribute to this failure to find differences is the use of oversimplified and decontextualized social stimuli to examine these behaviors (e.g., a solo...

Three experiments investigated whether the semantic informativeness of a scene region (object) influences its representation between successive views. In Experiment 1, a scene and a modified version of that scene were presented in alternation, separated by a brief retention interval. A changed object was either semantically consistent with the scene (non-informative) or inconsistent (informativ...

Four flicker change-detection experiments demonstrate that scene-specific long-term memory guides attention to both behaviorally relevant locations and objects within a familiar scene. Participants performed an initial block of change-detection trials, detecting the addition of an object to a natural scene. After a 30-min delay, participants performed an unanticipated 2nd block of trials. When ...

The detection of damaged building regions is crucial to emergency response actions and rescue work after a disaster. Change detection methods using multi-temporal remote sensing images are widely used for this purpose. Differing from traditional methods based on change detection for damaged building regions, semantic scene change can provide a new point of view since it can indicate the land-us...

Video Databases and video on demand represent an important application of the evolving Global Information Infrastructure. However, video querying involves a lot of user interaction and feedback based query refinement, which can generate large traffic volumes on the network if full video segments are sent. To aid in efficient Video browsing, search and retrieval across the network, we need to fi...
