		<abstract>Among techniques of digital image processing, fusion appears as an important tool because it is a method that combines images of different spectral and spatial characteristics to synthesize a new image with better spatial resolution than the original multispectral image. The image fusion methods are widely used in several sensing applications, so this paper analyzed the contribution of the image fusion from CBERS-2B (China-Brazil Earth-Resources Satellite) orbital of the CCD and HRC sensor by the IHS method (Intensity, Hue, Saturation) for detecting the edge of a stretch of the Itaparica Reservoir.  The technique was applied in bands 1, 2 and 3 of the CCD sensor (spatial resolution of 20 meters) and in the panchromatic band of the HRC sensor (spatial resolution of 2.7 meters, operating in the spectral range covering the visible and part of the near infrared). Spring 5.2.7 software was used to perform the tests and the Sobel filter for edge detection, as well as ArcGis 10.1 for adjusting and cropping HRC and CCD scenes. It was observed that the fusion technique presented a positive contribution, because the edges contours were less thick than in the original image allowing the visualization of more details. On the other hand, because of the application of the Sobel filter, fusion had flaws in edge detection in some stretches of the image.</abstract>
