Electricity energy consumption (EEC) has great effect on the government to make reasonable energy policy and has attracted great attentions of the power generation groups with the liberalization of competition in the electricity industry. In fact, the EEC is easily affected by many factors, including the climate factor and the gross domestic product. So, the precise forecasting of electricity energy...
In this paper an improvement of the performance for detecting faces in color images is proposed. This improvement is achieved by integrating the AdaBoost learning algorithm with skin color information. Firstly, the system searches the entire image for face candidates by skin color segmentation and morphological operations, then a powerful feature selection algorithm, AdaBoost is performed to automatically...
This paper proposes a novel technique for detecting faces in color images using AdaBoost algorithm combined with skin color segmentation. First,skin color model in the YCbCr chrominance space is built to segment the non-skin-color pixels from the image. Then, mathematical morphological operators are used to remove noisy regions and fill holes in the skin-color region, so we can extract candidate human...
Regarding big data set, the efficiency is low when the numeric-attributes with a lot of values. This article which applied SPRINT algorithm bases on "the pure intervals" in the graduation design process management system .The algorithm excludes the candidate splitter points in "the pure intervals" at first, then computes gini indexes remained, finally compares with the gini indexes...
