"Fiddler's neck" is an irritant contact dermatitis that frequently affects violin and viola players. The etiology of the skin changes associated with this condition are probably attributable to a combination of factors--including increased pressure, friction, poor hygiene, and excessive perspiration. Clinically, the lesions generally consist of a localized area of lichenification on the left si...

In this report we summarise our experiments with ADABOOST and its application to the problem of face detection. As a starting point, the Viola-Jones face detector ([1]) is reimplemented and some details of the implementation are discussed. Next, modifications of both the training and detection procedure are reported. In the learning phase, tenfold decrease in training time, without noticeable r...

A trained cascade for face detection with a reduced number of Haar-like features should be computationally efficient. The accurate classical scheme for selecting these Haar-like features is proposed by Viola and Jones, but the training process may take weeks. Recently, there have been several heuristics reducing the training time in a dramatic way but the selected weak classifiers are not as go...

Brief history of the violin. The emergence of the violin in Upper Italy: The violin evolved from the viola da braccio family between 1520-1550, the Upper Italian towns of Milan, Brescia, Cremona and Venice being the most important centers. The term “violin” (from the Italian word violino) is derived from the word viola and had the general meaning “small stringed instrument” rather than “small v...

This master thesis deals with real-time algorithms and techniques for face detection and face tracking in videos. A new approach is presented where optical flow information is incorporated into the Viola-Jones face detection algorithm, allowing the algorithm to update the expected position of detected faces in the next frame. This continuity between video frames is not exploited by the original...

Viola and Jones Algorithmand Viola and Jones, the conventional face-detecting methods, have the advantages in that they could help fast and clear face recognition. But they also have their own drawbacks. With Viola and Jones, detection of slanted face is hard, and Viola and Jonescannot provide the precise recognition of faces since the detected area in faces is rather wide depending on the envi...

Two or more components (e.g., objects, modules, or programs) interoperate when they exchange data, such as XML data. Currently, there is no approach that can detect a situation at compile time when one component modifies XML data so that it becomes incompatible for use by other components, delaying discovery of errors to runtime. Our solution, a Verifier for Interoperating cOmponents for findin...

This study was to evaluate anti-inflammatory and analgesic effects of the aqueous extract of leaves of Chromolaena odorata (Asteraceae) collected in Brazzaville-Congo. Acute inflammation was induced by using the carrageenan and formaldehyde models, and chronic inflammation by the cotton pellet induced granuloma model. Analgesic effect was evaluated by using the acetic acid-induced writhing, the...

Activation of nuclear factor-erythroid 2-related factor 2 (Nrf2) contributes to several beneficial bioactivities of natural products, including induction of an increased cellular stress resistance and prevention or resolution of inflammation. In this study, the potential of a crude leaf extract of Chromolaena odorata, traditionally used against inflammation and skin lesions, was examined for Nr...
