Image Registration is the process of aligning two or more images of the same scene taken at different times, from different viewpoints, or by different sensors into a common coordinate system. It has two main components: • Source Image (Moving): The image that is to be geometrically transformed to align with the reference image. • Reference Image (Fixed): The target image about which source image is to be geometrically transformed.
The process of lunar images registration involves finding match points between source and reference image and then aligning the source image with the reference image.

The process of lunar images registration involves finding match points between source and reference image and then aligning the source image with the reference image. The key challenges involved in this process are as follows: • Illumination variation: Illumination variation refers to changes in sun azimuth and elevation effect on the surface lighting conditions that affect the appearance of the lunar surface features which is hard to correlate. • Viewpoint variation: It refers to geometric distortions caused by different camera positions/orientations capturing the same scene. Objects appear shifted, scaled, rotated, or perspective-distorted depending on observing angle. • Scale Variation: Lunar imaging missions operate at vastly different altitudes and at different spatial resolutions.
