An Enhancing Approach for Typhoon Cloud Image

We develop an efficient approach for enhancing the contrast of single typhoon cloud image. We first perform an invert operation on an input image for capturing more detail information. Then we employ a simple but effective modified histogram model to generate the distribution function which enhances the contrast of the inverted image. The final enhanced typhoon cloud image is obtained through inverting the enhanced image. Compared with several enhancement methods, the proposed method achieves better subjective results and objective assessments. Furthermore, our method can provide a fast segmentation of typhoon eye.
