Facial expression is the natural means for human beings to show their emotions and motivations. The problem of unconstrained face recognition from remotely acquired images is addressed. When blurring comes to picture, face recognition becomes difficult. The main factors that make this problem challenging are image degradation due to blur and the appearance variations due to illumination and pose. Many of the approaches concentrate mainly on the blurring part alone. A blur-robust face recognition algorithm DRBF (Direct Recognition of Blurred Faces) and IRBF (Illumination-Robust Recognition of Blurred Faces) is proposed in this paper. This algorithm can easily incorporate prior knowledge on the type of blur as constraints. In addition to this, the illumination defects are also considered along with the blur problems. And the features of facial components such as eyes, nose, and mouth in gray images of faces are extracted and the facial expressions are identified.Keywords

A new, simple, accurate and sensitive UV - spectrophotometric absorption correction method has been developed for simultaneous determination of amlodipine besylate and olmesartan medoxomil in combined tablet dosage form. Methanol and distilled water were used as solvents. The wavelengths selected for the analysis were 363nm and 258 nm for amlodipine besylate and olmesartan medoxomil, respectively. Beer's law obeyed the concentration range of 1.25- 6.25 μg/ ml and 5 - 25 μg/ml for amlodipine besylate and olmesartan medoxomil respectively. The method was validated stastically.

Curcumin has an excellent safety profile having various pleiotropic actions, including anti-inflammatory, antioxidant, antitumoral, anticancer, and antimicrobial activities, with the potential for neuroprotective activity but the poor oral bioavailability limits its use as oral dosage form. The purpose of this study was to formulate and evaluate the transdermal drug delivery system of Ethosomes containing curcumin, a potent anti-cancer drug. Study on various formulation excipients revealed that all the excipients shown some variation which affected the vesicle size, zeta potential, PDI and entrapment efficiency. Batch prepared with 10 % of soya lecithin, 4.5 % of ethanol and 10% of cholesterol showed maximum entrapment efficiency of 81.2±3.12.In in vitro drug permeation studies using dialysis bag, the samples withdrawn in equal time intervals shown more drug release from the dialysis bag in comparison with that of inhouse paclitaxel gel which conform that the curcumin loaded ethosomal gel is a better formulation for the further studies. In ex vivo, permeation study using pork ear skin, curcumin loaded ethosomal gel showed the greater drug deposition on the skin > 60 % in 12 hrs for the better curability for the melanoma. Whereas inhouse paclitaxel gel shown < 60 % of drug deposition in 12 h. The comparison of both ethosomal gel and inhouse paclitaxel gel reveals that ethosomal gel shown maximum release within 12 hrs in both in vitro and ex vivo studies, which can be taken for the further in vitro cell line and in vivo study.Keywords
