  Various and different methods can be used to produce high-resolution
multispectral images from high-resolution panchromatic image (PAN) and
low-resolution multispectral images (MS), mostly on the pixel level. However,
the jury is still out on the benefits of a fused image compared to its original
images. There is also a lack of measures for assessing the objective quality of
the spatial resolution for the fusion methods. Therefore, an objective quality
of the spatial resolution assessment for fusion images is required. So, this
study attempts to develop a new qualitative assessment to evaluate the spatial
quality of the pan sharpened images by many spatial quality metrics. Also, this
paper deals with a comparison of various image fusion techniques based on pixel
and feature fusion techniques.
