Processing and Quantifying Images

  • David B. Williams
  • C. Barry Carter

Abstract

In this chapter we will equate processing with the use of the computer to analyze our data. We will simply use image processing to extract more information from the data than we can obtain by eye. The data will generally be an HRTEM image but could be other images or DPs. We’ll quantify spectra after we describe them in Part 4 of this text. In the past, the optical bench was also used for this purpose, but the number of optical benches is negligible compared to the number of computers now found in every TEM lab. Optical benches did allow us to form DPs which we could then modify to produce a processed image. This analog approach has now largely been replaced by its digital counterpart. The computer can be much cheaper than the optical bench and is far more flexible. The number of software packages which are designed for, or can easily be adapted to, TEM is also growing.
