jems contains a simple image processing engine that allows to apply a few processing algorithms to experimental images like:
- contrast enhancement, contrast inversion.
- point, line peak finding.
- threshold and binarization.
- noise filtering.
- etc.
Figure 1 shows an experimental SAED and Figure 2 shows the pattern after line detection. The visibility of the Kikuchi band is largely improved by convolving the pattern with a Prewitt kernel.
