Collecting and mining customer consumption data are crucial to assess value predict behaviors. This paper proposes a new procedure, based on an improved Random Forest Model by: adding indicator, joining the RFMS-based method K-means algorithm with Entropy Weight Method applied in computing index, classifying customers different categories, then constructing forecasting model whose RMSE is small...

High-resolution satellite imagery is expected to be a major source of 3D measurement of ground, especially automatic stereo plotting to generate DEM by stereo matching technology is highly required. Epipolarity is a very useful concept in processing stereo imagery, and it has been widely used in process images captured by frame cameras. Different from perspective image, every scan line of linea...
