Review on Different PAN Sharpening Methods
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 4
Abstract
In current technological development in electronics era have promoted real time remote sensing system to collect fine image resolution over the ground. The earth observation satellite such as Quick-bird, IKONOS, landsat etm+, CALIPSO uses the on-board optical imaging sensor while designing these sensors there are some limitation and in order to meet these limitations trade-off between the spatial resolution spectral resolutions and signal to noise ratio is made. Because of this reason optical system provides the data which consists of low resolution multispectral image and high resolution panchromatic image. High resolution colour image can be obtained from these available images by the process called as pan sharpening. This process combines low resolution multispectral image with high resolution PAN image to produce the resulting image which corresponds to multispectral images with same resolution as that of PAN image. This method provides effective way to obtain colour image with high spatial resolution for the better visual image from remote sensing system. In this paper the review of different pan sharpening methods is taken.
