The inferotemporal (IT) cortex of the monkey lies at the head of the ventral visual pathway and is known to mediate object recognition and discrimination. It is often assumed that color plays a minor role in the recognition of objects and faces because discrimination remains highly accurate with black-and-white images. Furthermore it has been suggested that for rapid presentation and reaction t...

AIM The aim of this study was to explore adult-trained perioperative nurses' practice of family-centered care (FCC). METHOD A qualitative research design with a hermeneutic phenomenological approach was used. In-depth interviews were conducted with six adult-trained perioperative nurses. Data analysis was guided by Colaizzi's seven-step framework, resulting in a composite description of perio...

Lung cancer has been the largest cause of cancer deaths worldwide with an overall 5-year survival rate of only 15%. Its symptoms can be found exclusively in advanced stages where the chances for patients to survive are very low, thus making the mortality rate the highest among all other types of cancer. The present work deals with the attempt to design computer-aided detection or diagnosis (CAD...

Hand gesture segmentation is a key step for gesture recognition. Based on the construction of a new color space of skin model, a new dynamic-thresholding segmentation approach named Adaptive Threshold Segmentation Algorithm (ATSA) was further developed and segmentation effect evaluation was conducted. Some images of hand gesture were processed by using ATSA and the Fixed Threshold Segmentation ...

For applications such as video surveillance and human computer interface, we propose an efficiently integrated method to detect and track faces. Various visual cues are combined to the algorithm: motion, skin color, global appearance and facial pattern detection. The ICA (Independent Component Analysis)-SVM (Support Vector Machine) based pattern detection is performed on the candidate region ex...

The color appearance of an object is significantly influenced by the illumination color. When illumination color changes, the color appearance of the object will change accordingly, causing its appearance to be inconsistent. Therefore, illumination condition must be set during the process of data aquisition when making a color model of an object. However, it is impossible to handle the illumina...

Received: 27 April 2013 Accepted: 6 August 2013 Abstract Background and Aim: Discoloration is among the most common problems of composite restorations. Color change over time compromises the main advantage of composite resins namely their high esthetics. In such cases, the restoration needs to be replaced. .The aim of this in-vitro study was to evaluate the effect of accelerated artificial agin...

In digital color imaging, it is of interest to transform the color scene of an image to the other. Some attempts have been done in this case using, for example, lαβ color space, principal component analysis and recently histogram rescaling method. In this research, a novel method is proposed based on the Resenfeld and Kak histogram matching algorithm. It is suggested that to transform the color...

In the present work, a low-pressure chemical vapor deposition (LPCVD) Ti0.17Al0.83N and state-of-the-art arc ion plating PVD-Ti1−xAlxN (x = 0.25, 0.55, 0.60, 0.67) coatings were deposited on cemented carbide substrate. The morphological, structural, electrochemical properties of LPCVD-Ti0.17Al0.83N compared. X-ray diffraction (XRD) results scanning electron microscopy (SEM) images revealed that...
