Hot Spots of the User Interface

In order to enable beginners to work with Epina ImageLab, here is a list of commands frequently used in everyday work:

The following list describes the interface's most important functions from top to bottom and from left to right:

Button Short Explanation
Open data file Allows the user to open a data file. By default the working directory of Epina ImageLab is used as the standard directory. Use the Preferences command in order to change the working directory.
Recently used files Select and open a data file from a list of the 16 most recently used files. The list is sorted according to the last usage of a file.
Dataset editor The dataset editor is used to create training and test datasets used for the development of classifiers.
Pixel mask editor This opens the pixel mask editor which is commonly used to mask pixels in a dataset that should be excluded from calculations.
Open Windows Selector One of the main problems in handling many open windows on a small screen is to locate a particular window. Moving the mouse to this selector automatically drops down a list of currently open windows. Selecting any of these windows brings the chosen window to the top. Please note that the behavior of this selector can be adjusted in the preferences of Epina ImageLab (option "Automatic Dropdown of the List of Open Windows").
spectral descriptor editor Opens the spectral descriptor editor.
MNF Transform Starts the Maximum Noise Fraction Transform.
PCA Opens the Principal Component Analysis tool.
VCA Opens the Vertex Component Analysis tool.
HCA (dendrogram) Opens the tool for Hierarchical Cluster Analysis.
k-means clustering Opens the k-means clustering tool.
Fuzzy c-means clustering Opens the tool for fuzzy c-means clustering.
PLS/DA classification Opens the tools used to develop PLS/DA classifiers.
Image stack Opens the image stack.
2D image properties Opens the properties of the 2D image.
Select spectrum If your data consists of several spectra per pixel (multisensor data) you can switch between the available spectra.
Location cursor Moving this cursor displays the spectrum at the location of the cursor (if the display mode is "spectral").
Spectral cursor Moving this cursor displays image at the wavelength/mass/(or whatever) of the cursor.
Copy to image stack Copies the currently visible image to the image stack.
Color scale adjustment Double click the color scale to open the color palette selector, drag the mouse accross the color scale to shift or resize the color scale (depending on the mouse position). See also color scale adjustments.
