ABSTRACT:
An image processing apparatus and method for identifying a safe landing location on the surface of the moon or planets calculates local average brightness and brightness variance in a neighborhood of each image pixel based on a digital image data obtained with a camera and determines whether each pixel represents a level and flat area based on the local average brightness and brightness variance calculated for each pixel, thereby extracting a desirable landing site.
