Program snapshot

Figure 5 shows the interactive controls. A resizeable image of the data or result appears in a second window on the screen. Buttons display the original image, 2D wavelet coefficients, or horizontal basis functions. Figure 2 was generated with this option. Sliders control the wavelength pass range in two ways. The top four set of sliders adjust the pass bounds as octaves above DC and below Nyquist for the horizontal and vertical. Decreasing the high bound an octave or two is interesting. Figure 3 was generated with these options. The bottom two sliders specify a global pass threshhold as percentage of maximum wavelet amplitude. Increasing the low bound 40 to 60 percent is interesting. Segmentation modes are to display the reconstruction directly or to use the reconstruction to mask the original data image. Figure 4 was generated with these options.
