Abstract
This article reviews the main principles of image analysis by a computer. The picture is stored in computer memory as a collection of picture elements (pixels), each located in 2-dimensional space and characterized by a grey value. A histogram of grey levels (grey level histogram) can be calculated by the computer and applied in thresholding. Other operations described include background noise smoothing, boundary enhancement, erosion, dilatation, and size distribution analysis.
