In this paper, we proposed an efficient method to address the problem of color face image segmentation that is based on color information and saliency map. This method consists of three stages. At first, skin colored regions is detected using a Bayesian model of the human skin color. Then, we get a chroma chart that shows likelihoods of skin colors. This chroma chart is further segmented into skin region that satisfy the homogeneity property of the human skin. The third stage, visual attention model are employed to localize the face region according to the saliency map while the bottom-up approach utilizes both the intensity and color features maps from the test image. Experimental evaluation on test shows that the proposed method is capable of segmenting the face area quite effectively,at the same time, our methods shows good performance for subjects in both simple and complex backgrounds, as well as varying illumination conditions and skin color variances.

abstract Acetyl hexapeptide-3 has been used in anti-aging topical formulations aimed at improving skin appearance. However, few basic studies address its effects on epidermis and dermis, when vehiculated in topical formulations. Thus, the objective of this study was to determine the clinical efficacy of acetyl hexapeptide-3 using biophysical techniques. For this purpose, formulations with and without acetyl hexapeptide-3 were applied to the ventral forearm and the face area of forty female volunteers. Skin conditions were evaluated after 2 and 4-week long daily applications, by analyzing the stratum corneum water content and the skin mechanical properties, using three instruments, the Corneometer(r) CM 825, CutometerSEM 575 and ReviscometerRV600. All formulations tested increased the stratum corneum water content in the face region, which remained constant until the end of the study. In contrast, only formulations containing acetyl hexapeptide-3 exhibit a significant effect on mechanical properties, by decreasing the anisotropy of the face skin. No significant effects were observed in viscoelasticity parameters. In conclusion, the effects of acetyl hexapeptide-3 on the anisotropy of face skin characterize the compound as an effective ingredient for improving conditions of the cutaneous tissue, when used in anti-aging cosmetic formulations.

Although the right fusiform face area (FFA) is often linked to holistic processing, new data suggest this region also encodes part-based face representations. We examined this question by assessing the metric of neural similarity for faces using a continuous carryover functional MRI (fMRI) design. Using faces varying along dimensions of eye and mouth identity, we tested whether these axes are coded independently by separate part-tuned neural populations or conjointly by a single population of holistically tuned neurons. Consistent with prior results, we found a subadditive adaptation response in the right FFA, as predicted for holistic processing. However, when holistic processing was disrupted by misaligning the halves of the face, the right FFA continued to show significant adaptation, but in an additive pattern indicative of part-based neural tuning. Thus this region seems to contain neural populations capable of representing both individual parts and their integration into a face gestalt. A third experiment, which varied the asymmetry of changes in the eye and mouth identity dimensions, also showed part-based tuning from the right FFA. In contrast to the right FFA, the left FFA consistently showed a part-based pattern of neural tuning across all experiments. Together, these data support the existence of both part-based and holistic neural tuning within the right FFA, further suggesting that such tuning is surprisingly flexible and dynamic.

Necrotising fasciitis is a fulminant, rapidly progressive infection associated with extensive tissue destruction and significant mortality. Given the robust blood supply of the face, periorbital necrotising fasciitis is rare in this region. Traditional management consists of prompt initiation of antibiotics and adequate surgical debridement. This report documents the outcome of Type 2 periorbital necrotising fasciitis in a 49-year-old, immunocompetent man, in whom negative pressure wound therapy, was combined with conventional measures. The negative pressure wound therapy was applied directly to the involved orbit, suggesting its safety and efficacy in relation to use over the orbit. Negative pressure wound therapy may be a useful adjunct to the armamentarium of the oculoplastic surgeon for the reconstruction of periorbital defects produced by the surgical debridement of periorbital necrotising fasciitis.

Abstract The paper analyzes the role of the national team of Spain denoted by the neologism La Roja in promoting patriotic sentiments and building national unity. In a 2014 study entitled Goles y banderas. Fútbol e identidades nacionales en España, Alejandro Quiroga Fernández de Soto argues that the successes of the team in 2008-2012 (Champions of Europe in Austria and Switzerland, World Champions in South Africa and again Champions of Europe in Poland and Ukraine), brought about a patriotic revival, while La Roja itself became an integrating factor which united the Spanish regardless of political differences and distinct identities. The assertion is highly debatable for two reasons: firstly, the resurgence of the national symbols was temporary and did not occur uniformly across the country, especially in Catalonia and the Basque Country; secondly, it would be more fitting to speak of journalistic patriotism rather than actual patriotic revival within the Spanish society. The paper critically assesses the patriotic discourse rooted in the successes of La Roja in 2008-2012. Their poor performance in the last major tournaments in 2014-2018 and absence of any particular euphoria surrounding the national team confirm that the wave of flags which swept the country in the successful period was not an expression of profound, patriotic renewal of national symbols. At most, it may be argued to have been a forced attempt to boost Spanish (centralist) nationalism in the face of the increasingly active peripheral nationalisms, especially its most radical, Catalan embodiment.

Face blindness can occur after injury to a variety of brain locations, and yet the regions critical for face recognition remain unclear. Cohen et al. show that lesions that cause face blindness map to a specific brain network, and use this to predict subclinical deficits in an independent lesion cohort.

We recorded magnetoencephalography using a neural entrainment paradigm with compound face stimuli that allowed for entraining the processing of various parts of a face (eyes, mouth) as well as changes in facial identity. Our magnetic response image-guided magnetoencephalography analyses revealed that different subnodes of the human face processing network were entrained differentially according to their functional specialization. Whereas the occipital face area was most responsive to the rate at which face parts (e.g., the mouth) changed, and face patches in the STS were mostly entrained by rhythmic changes in the eye region, the fusiform face area was the only subregion that was strongly entrained by the rhythmic changes in facial identity. Furthermore, top–down attention to the mouth, eyes, or identity of the face selectively modulated the neural processing in the respective area (i.e., occipital face area, STS, or fusiform face area), resembling behavioral cue validity effects observed in the participants' RT and detection rate data. Our results show the attentional weighting of the visual processing of different aspects and dimensions of a single face object, at various stages of the involved visual processing hierarchy.
