Introduction

Basically, a digital image is just an array of numbers arranged in rows and columns. Processing an image by enhancing its contrast, correcting its geometry, or classifying it into various categories means processing numbers with mathematical and statistical algorithms. The same image-processing techniques that are used for analyzing remotely sensed images from multispectral satellite sensors may be applied to small-format aerial photography (SFAP) (e.g., Kasser and Egels, 2002; Mather, 2004; Bahr, 2005; Richards and Jia, 2006; Jensen, 2005, 2007; Lillesand et al., 2008). Again, this chapter is not intended to be exhaustive, but meant to cover selected aspects that the authors consider specific or particularly useful for digital analysis of SFAP. It begins with aspects of geometric corrections and registration, continues to image enhancement techniques, image transformation and classification, and concludes with stereoscopic viewing and photogrammetric analysis. The final section gives a brief overview of software suitable for SFAP processing.
