Satellite Image data are now collected with different spatial, spectral, and temporal resolutions. Image fusion techniques are used extensively to combine different images having complementary information into one signal composite. The fused image has rich information that will improve the performance of image analysis algorithms. Pansharpening is a pixel level fusion technique used to increase the spatial resolution of the multispectral image using spatial information from the high resolution panchromatic image while preserving the spectral information in the multispectral image. Resolution merge, image integration, and multisensory data fusion are some of the equivalent terms used for pansharpening. Pansharpening techniques are applied for enhancing certain features not visible in either of the single data alone, change detection using temporal data sets, improving geometric correction, and enhancing classification. This paper mainly focus on incorporating various image fusion techniques that are available in the literature. Using commercial remote sensing software package Erdas Imagine V9.2. The performance of these image fusion techniques varies both spectrally and spatially. Hence, in this work qualitative and quantitative metrics for evaluating the quality of pansharpend images have been analysed. For this study, the principal component analysis, Brovay sharpening method, High pass filter, Ehlers method and Modified IHS methods are used.
