Based On Remote Sensing Image Of The Urban Transportation Information Extraction Research
Abstract: Pick to obtain information from images is the main source of human knowledge, especially one of the 21st century is the information time, how to efficient handling huge amounts of image data interpretation of social informatization is the whole process of the important problem facing. But with the development of science and technology, remote sensing technology has formed to high resolution and high spectral resolution development trend. And how to use these sources of remote sensing image completed the interpretation and information extraction becomes very important.
