Appendix A describes the generic JAVA framework used in all of the applets. This section presents the individual applets developed during the project. The choice of operators implemented was based on two criteria: (1) the set of operators could be linked into a sequence and (2) the operators would explore a variety of interactive facilities and image processing paradigms. These facilities included: text string inputs to specify test images, scalar parameter inputs, convolution kernel entry, chaining of operators, pointwise, local neighborhood and global operators, in-place and translated results, and single and multiple image inputs.
