We present a neural network based approach to key frame extraction in the compressed domain. The proposed method is an amalgamation of both the MPEG-7 descriptors namely motion intensity descriptor and spatial activity descriptor. Shot boundary detection and block motion estimation techniques are employed prior to the extraction of the descriptors. The motion intensity (“pace of action”) is obt...

the purpose of current article is to study the effect of sense of place on creating the urban identity in new cities. in order to fulfill the mentioned purpose, the key concepts of research and the theories related to the issue were studied. according to it, in order to collect the data, library method and note taking tool were used. the studies indicated the presence of human in the environmen...

Transformations of visuospatial mental images are important for action, navigation, and reasoning. They depend on representations in multiple spatial reference frames, implemented in the posterior parietal cortex and other brain regions. The multiple systems framework proposes that different transformations can be distinguished in terms of which spatial reference frame is updated. In an object-...

Representing the position of the objects independently from our own position is a fundamental cognitive ability. Here we investigated whether this ability depends on visual experience. Congenitally blind, late blind and blindfolded sighted participants haptically learnt a room-sized regularly shaped array of objects, and their spatial memory was tested to determine which spatial reference frame...

A quick group search optimizer (QGSO) is an intelligent optimization algorithm which has been applied in structural optimal design, including the hinged spatial structural system. The accuracy and convergence rate of QGSO are feasible to deal with a spatial structural system. In this paper, the QGSO algorithm optimization is adopted in seismic research of steel frames with semi-rigid connection...

BACKGROUND High tibial osteotomy (HTO) is used to treat medial compartment osteoarthritis of the knee in active patients with varus alignment. In this study we review the clinical and radiographic outcomes associated with the Taylor Spatial Frame (Smith & Nephew), and its use in HTOs, and we include an illustrative case report. METHODS In 7 patients with medial compartment osteoarthritis of t...

Spatial memories are often organized around reference frames, and environmental shape provides a salient cue to reference frame selection. To date, however, the environmental cues responsible for influencing reference frame selection remain relatively unknown. To connect research on reference frame selection with that on orientation via environmental shape, we explored the extent to which geome...

Tripartite systems are currently common to several theories concerned with distinguishing different spatial frames of reference (Levinson, 1996, 2003; Levelt, 1996; Tversky, 1996). The notion that such a 3-part spatial model (e.g. intrinsic, deictic, extrinsic) can be extended to temporal models is at least theoretically plausible (Levinson, 2003). The current study reviews three basic spatial ...
