At present, high resolution remote sensing images have made it more convenient for people to study the earth; however, they also bring some challenges for the traditional research methods. With1 the rapid increase of remote sensing imaging techniques over the past decade, a considerable amount of high-resolution remote sensing (HRRS) images are now available, thereby enabling us to study the ground surface in greater detail. In remote sensing we refer to three types of resolution: spatial, spectral and temporal. In addition to spatial, spectral, and radiometric resolution, the concept of temporal resolution is also important to consider in a remote sensing system. resolution also brings some new problems and difficulties for remote sensing image segmentation.
