The image fusion technique is widely used in various applications like military, remote sensing, security and medical imaging. In image fusion, two different images with similar index is fused to extract the exact information. The Landsat and Moderate resolution imaging spectroradiometer images taken from artificial satellite are not perfectly distinguishable. The principal component analysis, discrete cosine transform and discrete wavelet transform with spatial frequency are the existing methods used for fusing images. The principal component analysis and discrete cosine transform were applicable only for low precision and low quality applications. Also, the output image faced drawbacks that resulted in blurred image with low recognition rate. In order to obtain image clarity and accuracy, the top hat based moving technique with fuzzy inference system is proposed in this paper. The white top hat and black top hat …
