摘要:Abstract: Cloud is one of the important meterological elements that could be perceived by eyes. Cloud ob-servation could help us make weather forecast. Cloud cover estimation is part of cloud observation. The paper uses the method of threshold segmentation of digital image processing to estimate cloud amount. Compared with traditional artificial and ordinary instrument method, the measurement is more convenient and practical. The paper analyzes the result of three methods of image segmentation which are Otsu, max entropic thresholding and Mathematics expectation, and puts forward a modified method. The modified method works better on cloud image which shows higher cloud.
