Chapter 3: Digital Images

LogPolar

screendump of LogPolar

The LogPolar application warps an image to simulate the distortions inherent in log-polar sensor arrays. As the cursor moves over the image, the polar and cartesian coordinates of the underlying pixel are continually updated.

The application consists of source files LogPolar.java and LogPolarInfo.java. The latter is a class representing the information panel displayed below the warped image. Corresponding .class files are provided, and these class files have been packaged as a single JAR file, LogPolar.jar.

To install this application, copy the JAR file somewhere, then copy either the MS-DOS batch file LogPolar.bat or the bash shell script LogPolar.sh to an appropriate location and edit it to reflect the new location of the JAR file.
