FIT2D for General Image Processing Operations

The IMAGE PROCESSING (GENERAL) interface contains commands which allow normal mathematical operations and geometrical transformations to be applied to image data. Filtering operations are also available. The IMAGE PROCESSING (GENERAL) interface main menu is shown in Figure 11.

Figure 11: IMAGE PROCESSING (GENERAL) Interface Menu

As an example of using this menu the basic operation of subtracting one image from another is detailed. e.g. Subtracting a dark current image from a diffraction image. The following commands are used:

INPUT Input dark current image

EXCHANGE Place the dark current image in the memory

INPUT Input diffraction image

MATHS Enter MATHS sub-menu

SUBTRACT Subtract the memory image from the current data array image

EXIT Exit MATHS sub-menu

OUTPUT Save dark current subtracted data in a file

(It may be noted that the memory still contains the dark current image, so another diffraction image could be input without having to re-input the dark current.)
