Introduction Recent developments in partially parallel imaging (PPI) techniques provide new opportunities for motion artifact reduction [1-2]. One PPI technique that exhibits great potentials in many motion detection and correction scenarios is the GRAPPA operator [3], as the GRAPPA kernels can be flexibly positioned for k-space interpolation and extrapolation in any direction. This work propos...

An original approach for real time detection of changes in 5 motion is presented, for detecting and recognizing events. Current video 6 change detection focuses on shot changes, based on appearance, not mo7 tion. Changes in motion are detected in pixels that are found to be active, 8 and this motion is input to sequential change detection, which detects 9 changes in real time. Statistical model...

Monitoring of human activity requires people to be tracked as they move through the scene. Every tracking method requires object detection. We proposed a new method for detection and tracking of multiple moving objects under static background, based on motion detection, background subtraction using canny edge detection with edge difference between consecutives frames. Keywords—motion detection;...

The image segmentation method described in this paper has been developed as a pre-processing stage to be used in methodologies and tools for video/image indexing and retrieval by content. This method solves the problem of whole objects extraction from background and it produces images of single complete objects from videos or photos. The extracted images are used for calculating the object visu...

Nakayama and Tyler (1981) disentangled the use of pure motion (speed) information from spatial displacement information for the detection of lateral motion. They showed that when positional cues were removed the contribution of motion or spatial information was dependent on the temporal frequency: for temporal frequencies lower than 1Hz the mechanism used to detect motion relied on speed inform...
