Images and Imaging Operations

Images are at the core of vision, and there are many ways—from simple to sophisticated—to process and analyze them. This chapter concentrates on simple algorithms, which nevertheless need to be treated carefully, for important subtleties needto be learned. Aboveall, thechapteraimstoshowthatquitea lot can be achieved with such algorithms, which can readily be programmed and tested by the reader.

Look out for:

• the different types of images—binary, gray-scale, and color.

• a useful, compact notation for presenting image processing operations.

• basic pixel operations—clearing, copying, inverting, thresholding.

• basic window operations—shifting, shrinking, expanding.

• gray-scale brightening and contrast-stretching ...
