This paper presents innovative on-line Java-based educational DSP software modules that were developed to render possible on-line laboratories for two-dimensional digital signal processing. The developed software modules provide on-line 2-D DSP capabilities, including 2D signal generation, 2D FIR filter design & implementation, and 2D transforms. On-line image processing capabilities are also provided, including image restoration and enhancement. In order to illustrate 2D concepts graphically, contour (2D) and perspective (3D) plots have also been implemented and incorporated as part of the developed software tools. On-line laboratory exercises have been developed in the aforementioned areas for use in the graduate-level multidimensional signal processing and image processing courses at ASU. Statistical and qualitative evaluations are presented to assess the effectiveness of the developed on-line 2D DSP software and laboratories in improving the learning experiences of the students.
