Abstract: Citrullus lanatus L. (Cucurbitaceae) known as Water melon is an edible fruit in many countries especially Nigeria. Chemical composition, phytochemical, physicochemical and antioxidant properties of the dried seeds of C. lanatus were determined to understand its potential health benefits since oil extract from a number of fruits, nuts and seeds are used in cooking, soap making and as ingredient in confectioneries of baked or fried foods. Dried and pulverized Watermelon seeds were extracted using hexane at 60-70oC. Standard methods were used to determine phytochemical and physicochemical parameters. The chemical composition of the oil was determined using Gas-Chromatography – Mass Spectrometry (GC-MS) while antioxidant activity was determined using 2, 2- diphenylpicrylhydrazyl radical (DPPH) and reducing power methods. Results showed that the light yellow oil with an average yield of 41.32% showed the presence of terpenoids, phenolics, glycosides, and carbohydrate. Physicochemical para

Abstract: Pill color is applied as one of important features for pill identification; however, most of pill color is white. It’s difficult to classify two similar white pills because pill’s color is sensitive to luminance intensity. To reduce its luminance-intensity effect, RGB color is converted in term of YUV component because when its luminance intensity is increased, only its Y value is increased but its U and V values are almost constant. Therefore, its U and V values can be directly applied for image recognition. In this report, we propose luminance compensation based on background shadow to compensate luminance-intensity effect in Y value. When its luminance intensity is increased, Y value of background is also increased but Y value of pill shadow is slightly decreased. Therefore, difference between Y value of background and its shadow is effectively applied for luminance compensation. Experimental results confirm an effectiveness of our proposed compensation method.
