Region-based approaches have been proposed to computerassisted colorization problem, typically using shape similarity and topology relations between regions. Given a colored frame, the objective is to automatically colorize consecutive frames, minimizing the user effort to colorize the remaining regions. We propose a new colorization algorithm based on graph matching, using Belief Propagation t...

Spatial prepositions work as pointers to localize objects in space. For instance “The book is over the table” indicates that the located object (LO) is somewhere “over” the reference object (RO). To understand where the LO is people need to assign direction to space (selecting a reference frame). Three experiments are reported which investigated the reference frame conflict between LO and RO. W...

The Taylor Spatial Frame (Smith & Nephew, Memphis, TN) is a powerful tool in providing gradual correction of deformity. The Taylor Spatial Frame has the potential to allow for very accurate corrections achieved over one or more schedules through the use of the software on www.spatialframe.com. The accuracy of the frame is contingent upon the input of precise parameters. The correction occurs ab...

A sectionally complemented modular lattice L is coordinatizable if it is isomorphic to the lattice L(R) of all principal right ideals of a von Neumann regular (not necessarily unital) ring R. We say that L has a large 4-frame if it has a homogeneous sequence (a0, a1, a2, a3) such that the neutral ideal generated by a0 is L. Jónsson proved in 1962 that if L has a countable cofinal sequence and a...

In human robot dialogue, identifying intended referents from human partners’ spatial language is challenging. This is partly due to automated inference of potentially ambiguous underlying reference system (i.e., frame of reference). To improve spatial language understanding, we conducted an empirical study to investigate the prevalence of ambiguities of frame of reference. Our findings indicate...

We present results from an experiment studying how people mentally integrated partial configurations of objects shown across a sequence of displays with varying matches between frames of reference. Consistent with previous research on spatial updating, performance was better when the frame of reference in the final display aligned with the main display axes (up/down, left/right) than when it al...

Compressed video may possess a number of artifacts, both spatial and temporal. Spatial compression artifacts arise as a result of quantization of the transform-domain coefficients, and are often manifested as blocking and ringing artifacts. Temporal limitations in compressed video occur when the encoder, in an effort to reduce bandwidth, drops frames. Omitting frames decreases the reconstructed...

Spatial navigation can be based on different, i.e. the egoand theallocentric reference frames. For successful orientation in real environmentsboth frames of reference are active and can be used dependent on therequirements of the task. To separate brain electrical activity dependent on theuse of the egocentric and the allocentric reference frame we investigated spatialnaviga...

population density and spatial distribution of thrips tabaci lindeman on seven soybean varieties (williams, tellar, sahar, dpx, l17, sari and zane) and one genotype (ks3494) were studied in tehran region, during 2007. the highest population density of the thrips per leaf was recorded on dpx and on ks3494 (0.810.05 and 0.800.05, respectively). the lowest population density was observed on l17 ...

The human visual system seems to be capable of temporally integrating information in a video sequence in such a way that the perceived spatial resolution of a sequence appears much higher than the spatial resolution of an individual frame. This paper addresses how to utilize both the spatial and temporal information present in an image sequence to create a high-resolution video still. A novel o...
