Studies with time-limited point-lights suggested that biological motion does not require local motion detection. These studies used walkers seen from the side, but biological motion perception excels also when walkers are oriented toward the observer, or in intermediate, half-profile views. In perspective projection, the local motion of points on the body provides a cue to the 3D structure of t...

OBJECTIVE To analyze anteroposterior soft tissue facial parameters for a sample of white Brazilian adults and to compare these measurements with the values proposed for white North American adults. MATERIALS AND METHODS Facial profile photographs were taken of 59 white Brazilians (30 men and 29 women) with normal occlusions and balanced faces with ages ranging from 18 to 30 years. The indepen...

Breast Thermography is an emerging medical imaging tool, used for early detection of breast cancer. The growing tumor in the breast will cause the occurrence of some asymmetric heat patterns in the left and right breast. Asymmetry analysis of left and right breast is used for detecting the breast cancer from the breast thermogram images. This paper presents a method for segmenting the left and ...

We propose integrating projection profile matching into a 1.5 Tesla clinical magnetic resonance (MR) scanner system to track a target organ in real-time for MRI guided therapy. As soon as a scanner acquires echoes, MR echo data are transferred immediately from the scanner to an “on-thefly” processing computer that executes projection profile matching, image reconstruction, image registration an...

This paper discusses the theoretical limits for resolution (number of pixels) and maximum contrast for clipped Gaussian and Uniform profile beams in scanning display systems. The results are applicable to scanning microdisplays (e.g. Virtual Retinal Display™) and scanning projection displays.

Primary somatosensory cortex (S1) receives two distinct classes of thalamocortical input via the lemniscal and paralemniscal pathways, the former via ventral posterior medial nucleus (VPM), and the latter, from the posterior medial nucleus (POm). These projections have been described as parallel thalamocortical pathways. Although the VPM thalamocortical projection has been studied in depth, sev...

The mature cerebral cortex contains a staggering variety of projection neuron subtypes, and a number of complementary studies have recently begun to define their identity and embryonic origin. Among the different types of cortical projection neurons, subcerebral projection neurons, including corticospinal motor neurons (CSMN), have been extensively studied and some of the molecular controls ove...

Objective: To evaluate the influence of age, gender, sagittal occlusal relationship, facial pattern and 8 facial profile measures on profile aesthetics. Methods: Contingency tables, chi-square test and Cramer’s coefficient were used to evaluate the possible association between the scores assigned by 32 examiners (14 orthodontists, 12 laypeople and 6 artists) to the aesthetics of the profile of ...

This paper describes the extraction of the facial profile from a frontal view to provide a measure for automatic face recognition. The profile is derived from the intensity projection of the face image and is described using the Walsh power spectrum. Results have demonstrated its potential as a measure for face recognition whilst it remains relatively immune to head movement and to small change...
