This paper presents a novel method to grade the date fruits based on the combination of shape and texture features. The method begins with reducing the specular reflection and small noise using a bilateral filter. Threshold based segmentation is performed for background removal and fruit part selection from the given image. Shape features is extracted using the contour of the date fruit and tex...

The process of photo-identification images of the blue whale (Balaenoptera musculus), is made manually; this process classifies images blue whale through its dorsal fin characteristics. The features are extracted visually, which can generate errors at the moment of classified. In this work an image classifier blue whale is presented, which have features such as color pigmentation, background im...

Our goal is to extract the names of key entities from written U.S. diplomatic communications and then to apply natural-languageand sentiment-based clustering to these entities using contextual features extracted from the data. We extract entities using an off-the-shelf statistical NLP package, and then seek to generate meaningful clusters of entities in an unsupervised fashion. To do so, we exp...

In this work, a neuro-fuzzy (NF) simulation study was conducted in order to screen candidate reservoirs for enhanced oil recovery (EOR) projects in Angolan oilfields. First, a knowledge pattern is extracted by combining both the searching potential of fuzzy-logic (FL) and the learning capability of neural network (NN) to make a priori decisions. The extracted knowledge pattern is validated agai...

A method of face recognition based on multiscale principal component analysis (MSPCA) is presented in this paper. Initially face area is extracted from the given face image using Adaboost face detection algorithm. From the face area, regions of interest such as eyes, nose and mouth part are extracted by dividing it along horizontal and vertical directions. Then MSPCA is employed on these region...

The effects of temperature, light, oxidant, soluble sugar, food additive (i.e. citric acid, benzoic acid, and ascorbic acid) and metal ions of K, Ca, Cu, Al, Mn, Fe, Sn, Mg on the stability of anthocyanin extracted from the kernels of novel inbred line super dark maize (SDM) with the strategy of HCl-carbinol were systematically analyzed. The results showed that the extracted anthocyanin was ste...

This paper proposes a novel method for extraction of eyebrow contour and chin contour. We first segment rough eyebrow regions using spatial constrained sub-area K-means clustering. Then eyebrow contours are extracted by Snake method with effective image force. For chin contour extraction, we first estimate several possible chin locations which are used to build a number of curves as chin contou...
