Background: A special pillow was designed to redistribute mechanical stress during sleeping in order to slow down the formation of facial skin wrinkles. Objective: To investigate whether sleeping on a specially designed pillow reduces facial skin wrinkles. Participants and Methods: A 28-day pilot study was carried out in which fifteen healthy female volunteers aged 23 55 years (mean age 35. 6 ±...

This paper addresses the problem of visualizing multidimensional scalar functions. These functions are often encountered in fields such as Engineering, Mathematics, and Physics to understand and model complex phenomena. We propose a novel method based on the dimension reduction philosophy called HyperCell. Its basic concept is to represent the function by means of dynamic orthogonal low (1D, 2D...

Region-of-interest (ROI) detection plays an important role in filtering out pornographic images. Skin-color models, as a traditional approach, extract skin-color regions as ROI. However, the approach is difficult to differentiate between human skins and other objects with the skin-color. Furthermore, skin-color regions are always larger than the subareas containing pornographic parts. In this p...

this research, applied as a survey approach aimed at investigating farmers’ tendency and attitudes toward agricultural water management styles (wmss). therefore, using cochran’s formula and simple random sampling, 244 farmers were selected in doroudzan region, iran. the data were acquired by face-to-face structural interviews and as well through a questionnaire that consisted of closed and open...

velvety hyperpigmentation in the neck ( fig. 2 ), axillae and the groin. Furthermore, the dorsa of the hands had brown thickened skin with a pebbly appearance ( fig. 3 ) and the palms showed rugose thickening with more pronounced skin markings ( fig. 4 ). His general and systemic clinical examination was otherwise unremarkable. What are the clinical diagnoses and, more importantly, which pulmon...

Facial feature extraction is a fundamental problem in image processing. Correct extraction of features is essential for the success of many applications. Typical feature extraction algorithms fail for low resolution images which do not contain sufficient facial detail. In this paper, a region-based super-resolution aided facial feature extraction method for low resolution video sequences is des...

We present a syndrome manifested in two half brothers and their two maternal aunts which is characterised in the two boys by severe mental retardation and craniofacial dysmorphism (broad, coarse features and marked plagiocephaly with flattened occiput), and in the aunts merely by moderate mental retardation without dysmorphic features. The brothers do not seem to fall into any previously descri...

Recently medical cosmetic has attracted significant business opportunity. Micro cosmetic surgery usually involves invasive cosmetic procedures such as non-ablative laser procedure for skin rejuvenation. However, to select an appropriate treatment for skin relies on accurate preoperative evaluations. In this paper, an automatic facial skin defects detection and recognition method is proposed. Th...

Nowadays, how to evaluate image quality reasonably is a basic and challenging problem. In view of the present no reference evaluation methods, they cannot reflect the human visual perception of image quality accurately. In this paper, we propose an efficient general-purpose no reference image quality assessment (NRIQA) method based on visual perception, and effectively integrates human visual c...
