in this article I present a method to use Viola and Jones algorithm for hand gesture recognition. A training method and an algorithm to choose the most likely gesture have been suggested. Tests under low cluttered environment show good detection rate. Keywords-; Hand Gusture, Viola and Jones

In this paper we present two improvements over Viola and Jones [1] training scheme for face detection. The first is 300-fold speed improvement over the training method presented by Viola and Jones [1] with a modest increase in execution time. The second is a principled method for determining a cascade classifier of optimal speed. We present some preliminary results of our methods.

Chromolaena odorata (Family: Asteraceae) synonyms as Eupatorium odoratum is a traditional medicinal plant that is widely used for its wound healing property. In particular, the several parts of this herb have been used to treat wounds, burns, and skin infections. Furthermore, it has also been shown to possess anticancer, antidiabetic, anti-hepatotoxic, anti-inflammatory, antimicrobial, and anti...

The development of HIV-1 protease inhibitors (HPIs) in highly active antiretroviral therapy (HAART) has dramatically decreased AIDS mortality. However, HPIs exhibit suboptimal therapeutics in vivo due to their intrinsic low oral absorption and rapid efflux via ATP-binding cassette transporters. These attributes facilitate uninhibited viral propagation and rapid selection of drug resistant HIV-1...

BACKGROUND Viola odorata L. belongs to Violaceae family and is native to Iran. It is used in the form of Almond-Violet oil in traditional Persian medicine (TPM) since ancient times. Almond-Violet oil was used for the treatment of insomnia, headache, cough, and fever based on TPM textbooks. There are two methods for the preparation of Almond-Violet oil. The first is macerating voila flowers in s...

to be the soloist in William Walton's Viola Concerto. Perhaps it's more a fantasy, than an ambition, as I'm not a good enough viola player to manage it. But if I were to have a go, my main experience of learning things has been in medicine. Is learning music the same? Perhaps I should start by writing some competency statements. Let's assume, that in order to start the module 'Walton's Viola Co...

Ageratum conyzoides, Chromolaena odorata, and Lantana camara, are common weed species in Cameroon. Essential oil extracts from their leaves were tested for efficacy on the morality of the maize grain weevil, Sitophilus zeamais (Coleoptera, Curculionidae). Concentrations of the essential oils relative to the maize grains of 0.013, 0.025, 0.05 and 0.1% (v/w) were used for A. conyzoides and 0.063,...

In this work Eucalyptus grandis and Dipteryx odorata were submitted to photodegradation by ultraviolet radiation. The effect of ultraviolet radiation irradiation on the color change and chemical composition of each wood flour were evaluated. The samples were submitted to a total of 500h of artificial weathering using condensation stages and ultraviolet radiation B irradiation cycles. The change...
