Imagery: Virtual Lab for Computer-Aided Training on Digital lmage Processing

Abstract

Imagery is an intuitively-easy-to-use Virtual Lab to be used as a Digital Image Processing (DIP) laboratory, allowing the user to experiment with DIP algorithms, enabling him to see their effects on images included by its author and also on those of the user. Reflecting the specialization field if its author, Imagery includes sorne modules dealing with algorithms used in Invariant Pattern Recognition. Research papers and books on DIP deal with algorithms to digitally operate on images, and generally sorne images to show the effects of those algorithms are included, however most times those images are not enough to make evident al!the potential of the algorithms. In this paper the creation oflmagery, a Virtual Lab for Computer Assisted Education (teaching and learning) ofDIP is reporte d. Imagery may be u sed in the classroom, in the lab and at home. The advantage ofusing software to teach (learn) a given image transformation like those performed in DIP, is that with the help of the software the transformations can be appreciated in real time, control parameters can be varied and the corresponding effects appreciated. Even though the author has included sorne supporting theory in the software, Imagery is a very useful complement to a specialized textbooks and classes.
