Abstract

We introduce a four-stage process for urban construction edge detection using IKONOS images. The four stages include: (1) binary image processing, (2) pixel swapping by using different kennels to separate pixels according to the gray level of the image, in this paper 8 adjacent kennels are used, (3) interactive analyzing and selecting numbers representing edges, (4) using many edge images based on image gray level, in this paper we introduce three gray level edge detection processes.
