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.
Source for this operator.
On the input image is drawn a red line. This line corresponds to the line along which the image will be reflected.
The only input to this operator is the slide bar which is used to change the angle of the line of reflection by sliding it back and forth. The angle can also be set by entering an integer value into the box.
As well as being able to change the angle of the line of rotation, the position of the line can also be altered. This is done by clicking in the input window. The point at which the user clicks defines a point through which the line will pass.
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.
