Preliminaries on Image Processing

This chapter provides an introduction to digital image processing. With a brief review on file formatting of images, it addresses the well-known frequency domain transforms such as discrete Fourier and discrete cosine transforms, and applies these transforms in pre-processing/filtering a given image. The principles of image segmentation are then outlined. Various algorithms for labeling of segmented images are then presented for subsequent application in object recognition. Some algorithms on high-level vision, including object recognition and image interpretation are also introduced in this chapter.
