Gabor Filter Visualization

We present a system for the visualization of an important signal processing techniquea Gabor Filter bank’s response to an image. To do this, one must overcome the problem that no multi-dimensional space can be shown in a a single, static graph. We use an interactive widget to change the visible range of the projected dimensions, and additional graphics which summarize the responses in the projected dimensions. Thus, though we view this four-dimensional space through 2-dimensional projections, we allow the user to understand all dimensions, not just the plane of projection. We found that the implemented system helped in getting a better understanding of Gabor filter responses. We think that use of a domain dependent interaction tool and additional summarization graphics may be useful in a more general Information Visualization setting.
