This paper shows the image fusion techniques to complement and calibrate weather radar images present in terrestrial using meteorological satellite images. To calibrate the images weather radar images implemented a fusion method was used discrete wavelet transform (DWT) mathematics tool. As there is a family of wavelets, wavelets is necessary to determine which offers the best results, and it was determined, with the correlation between the results of different wavelet and fusion of the images used in each fusion. We defined a methodology for selecting global threshold segmentation and a methodology for calibration of terrestrial radar images. Following the methodology of calibration images, some results are generated and displayed its advantages. The methodology of calibration images, some results are generated and displayed its advantages.

Palavras-chave : Discrete wavelet transform; histogram; image fusion; image segmentation.
