Effects of intrinsic structural and conformational properties on segmental orientation in uniaxially deformed copolymers are considered. Depedence of segmental orientation on equilibrium values of bond angles, torsional states, and probability distribution of rotameric states is studied. Calculations are carried out for chains with independent as well as pairwise interdependent rotameric states...

Examined the representation of real-world events in memory as a function of orientation toward a videotaped sequence in which 2 people play a board game. In 4 experiments, analyzed subjects' segmentation of the videotaped sequence into events, using a technique developed by Newtson (1973). A comparison of segmentation patterns with performance on recognition, recall, and cued-recall tasks indic...

In this paper a DWT based steganography in frequency domain, termed as ATFDWT has been proposed. Here, the cover image is transformed into the time domain signal through DWT, resulting four sub-image components as „Low resolution‟, „Horizontal orientation‟, „Vertical orientation‟ and „Diagonal orientation‟. The secret message/image bits stream in varying positions are embedded in „Vertical orie...

In recent years, in order to perform the 3D measurement using video image sequences from the freely moving plat-form, the exterior orientation technique that uses video image sequences has widely been investigated in the field of computer vision. This problem is called as “Structure from Motion” or “Simultaneous Localization and Mapping”. In these techniques, the estimation of exterior orientat...

OBJECTIVES To study the most frequent artifacts of punch biopsies of the healthy oral mucosa, distinguishing between those attributable to the surgical technique and those resulting from sample processing in the laboratory. STUDY DESIGN A total of 186 samples of oral mucosa (dorsal lingual mucosa) were obtained from 186 adult albino rats by the experienced oral surgeons, evaluating the presen...

CT Colonography (CTC) is an emerging imaging technique for colon screening. It is possible to extend this technique to automatically detect colonic anomalies. In order to improve the detection rate of the potential polyps, it is desirable to analyse plane sections orthogonal to the colon centreline rather than the axial CT slices. This paper describes a fast artefact free method for orthogonal ...

The processing of orientations is at the core of our visual experience. Orientation selectivity in human visual cortex has been inferred from psychophysical experiments and more recently demonstrated with functional magnetic resonance imaging (fMRI). One method to identify orientation-selective responses is fMRI adaptation, in which two stimuli-either with the same or with different orientation...

Capturing live motion has gained considerable attention in computer animation as an important motion generation technique. Canned motion data comprise both position and orientation components. Although a great deal of signal processing methods are available for manipulating position data, the majority of these methods cannot be generalized easily to orientation data due to the inherent non-line...

Pedicle screw insertion technique has made revolution in the surgical treatment of spinal fractures and spinal disorders. Although Xray fluoroscopy based navigation is popular, there is risk of prolonged exposure to Xray radiation. Systems that have lower radiation risk are generally quite expensive. The position and orientation of the drill is clinically very important in pedicle screw fixatio...

Estimation of human orientation is considered a key configuration to study and understand human behaviours. There have been many works focusing on this. However, most of previous works are sensor-based technologies but visual-based technologies. In this paper, we proposed a method to estimate the orientation of human in a given image patch. We have observed the performance of a feature called H...
