TILLvisION Tutorial

TILLvisION - Basics

The Main Window

When starting TILLvisION, the Main Window containing the Menu, Toolbars and a Status bar (at the bottom of the window) opens.

The screenshot shows a HELA experiment. You can see four open Views (one Workspace, two Images, and a Kinetic).

The TILLvisION Document, Objects and Views

The TILLvisION document is called Workspace (here: Hela2sm.vws). It may contain different elements or objects. All objects can be stored in one file, as a database.

The different objects are:

images, palettes or look-up-tables, kinetics, histograms, profiles, BASIC macros, embedded Word or Excel documents, object analyses, etc.

One document file may contain an unlimited number of objects. The objects carry unique names that allow them to be distinguished from each other. To decrease load and save times of a TILLvisION file you can optionally save only links in the document and keep big image sequences or other objects on disk. They will only be loaded on demand.

Data Types and Dimensions

The basic object data structure has five dimensions. Applied on images, this means that an image may have a width and height, any number of channels or bands (i.e. red, green and blue for color or any number for multi-band satellite images), it may have a spatial depth (several image slices stacked on top of each other) and a temporal duration to create film strips or a sequence.

The Object/View Structure

The structuring in objects and views provides several important advantages. It is possible to show the same object in more than one view. You may view images with different zoom factors or with different active palettes. You can also show images or kinetics graphically and numerically.

The Kinetic View

The Kinetic View is usually displayed as mean or integrated gray-scale value versus frame number (graphical view). Under numerical view a spreadsheet appears containing columns of the gray-scale values and the time information. You can easily export the spreadsheet via the clipboard or use the Macro OLExcel.bas to create an embedded Excel document.
