The IMAGE PROCESSING (GENERAL) Interface

The IMAGE PROCESSING (GENERAL) interface contains general commands for operations which manipulate images, such as adding, dividing, transposing, and filtering. These are the typical commands you will find in any image processing software. The IMAGE PROCESSING (GENERAL) main menu is shown in Figure 24.

Figure 24: The IMAGE PROCESSING (GENERAL) Main Menu

The following commands are available (in order displayed in the menu from left to right, top to bottom):

EXIT: Exits the IMAGE PROCESSING (GENERAL) interface and returns to main ``scientific interface'' menu. Note: data can be moved from one interface to another.

DISPLAY: Enter the GUI general display menu, assuming that data has been defined. This is used to display the data in the current program array in a variety of different styles.

EXCHANGE: transfers data from the ``main program array'' to the ``memory array'', and vice versa. This may be useful to save some data whilst another operation is overwriting the ``main program array''.

FILTER: starts a sub-menu which allows various filtering and smoothing of the data (see sub-section below).

?: Help text with short explanation of commands.

FULL: Sets the extent of the ``region of interest (ROI)'' or ``active data region (ADR)'' to be the whole of the currently defined data. This may be useful after the ``ZOOM-IN'' command.

GEOMETRIC: starts the Geometric operations sub-menu which allows various transformations to be applied to the data (see sub-section below).

INPUT: starts an interactive file selection tool to allow selection of directories, and of a file for input (see Section 5.1, Page ).

HELP: Detailed help text on the interface and the available commands.

OPTIONS: Starts the general GUI OPTIONS sub-menu which allows various display options to be modified, and control of the graphical output style. Used to alter the colour table, etc. after data has been input (see Section 5.5, Page ).

OUTPUT: General GUI output menu. Saves the current "region of interest (ROI)" in a selected file with a choice of file formats.

MATHS: starts a sub-menu which allows various unitary and binary mathematical operations to be performed pixel by pixel on the data.

PRINT: Save the currently displayed data image as a PostScript file. You are prompted for the name of the output file to create. After the file is fully written, it may be sent to a PostScript printer for printing. Note: It can take some time to create a file of a large 2-D data-set, and often even longer for the file to be printed.

MOVEMENT: starts a sub-menu which allows movement within the currently defined data.

UN-ZOOM: increases the size of the current ``region of interest'' (ROI).

ZOOM-IN: allows a sub-region of the data to be selected and displayed. It should be noted that all operations including OUTPUT only work on the current selected region. Care needs to be taken when using ZOOM-IN that subsequent operations are intended for only the current sub-region. The full available data region may be selected by using the FULL button.

Z-SCALING: starts a sub-menu which allows the false colour/ grey scale used to display image intensities to be changed. Different automatic and fixed scaling methods can be selected.
