Abstract :
Because of the effects of various factors in remote sensing image acquisition process, the remote sensing image has a low quality. This paper uses histogram equalization, histogram specification and wavelet transformation respectively to realize image enhancement. The image is satellite remote sensing image of pingtan island of Fujian province. The histogram equalization can adjust the whole image contrast automatically. While histogram specification enhances the contrast of a grayscale range selectively. Wavelet transform is an analysis method of time-frequency localization.
