An Improved Algorithm Based on IHS Transform for the Fusion of Object and Scene

Since the existing object-scene fusion method based on IHS transform has two defects: emergence of the scene image’s illusion in target area and the illumination inconformity of the fusion object, this paper proposes an improved algorithm through rearranging the hue component and saturation component of the new scene image which are used to carry out IHS inverse transform. Subjective quality evaluation and objective quality assessment data of comparative fusion experiment results show that the new algorithm not only can get rid of the two drawbacks of the existing object-scene fusion method based on IHS transform effectively and achieve better fusion result in the application of object-scene fusion, but also performs fast.
