G. Peano published a paper of space-filling curve in 1890. There are several applications using this curve in the area of image processing, computer graphics, etc. This paper presents a region-based scanning technique for image compression which we call an adaptive space filling scan (ASFS). In order to generate the ASFS, we make use of a minimum spanning tree technique. From several experiments for image compression, it is confirmed that in comparison to JPEG, acceptable quality images can be obtained at the same bit-rates.
