The following are instructions on how to run the applets which are part of the HIPR package. These applets are designed to allow the user to try out the operators which are outlined in the worksheets.
You may want to review the general instructions first, which gives a demonstration overview, JAVA details, browser details, known bugs, etc.

The pull down menu labeled Wrap/No Wrap allows you to toggle whether or not the image is wrapped around once it has been translated.
To define the translation which the image must undergo, a line is drawn in the input window whose direction is the direction the image is to be translated and whose length is how far the image is to be translated. To define the line click and hold on the input window and drag the mouse. This draws a line from the clicked point to the current mouse point. When the mouse button is released the destination point of the line is defined and it is drawn on the screen.
It is also possible to define the translation line using the two editable textfields. The values in these are updated when a line is defined using the mouse to indicate the current translation, however if new values are entered in here then the corresponding changes are made to the line on the screen.
The output is displayed to the right of the input image.
Pressing the green start button causes the operator to run. Pressing the Stop button causes the operator to stop running. This is useful if the system being run on is very slow and the operator is taking a long time to complete.
The time box shows the amount of time which the operator took to complete the process on the input image.
You can inspect the input and result image pixel values by depressing the left mouse button and moving the cursor over the desired pixel. The pixel coordinates and gray-level value are displayed underneath the image. Note that some images are larger than the displayed 256x256 display window. Larger images are subsampled in an appropriate manner.
You can find out about known problems with the system here.
