2 Basic Principles of Subpixel Mapping

DOI: 10.1201/9781003279082-2

2.1 INTRODUCTION

Subpixel mapping is an important part of mixed pixels processing, which is a follow-up step of spectral unmixing. The mainstream subpixel mapping mainly includes two steps: subpixel sharpening and class allocation. This chapter starts from the basic principles of subpixel mapping. Firstly, the spectral unmixing methods that are used to obtain the low-resolution abundance images are summarized. Then the commonly used methods of subpixel sharpening and class allocation are introduced. Finally, the main evaluation methods and experimental models used in this paper are described.
