Visualisation of the first class

The wavelet coefficients can be represented in several ways. Five visualisation tools are available in MIDAS.

• Through the command visual/plan, a window is created for each scale. The user can select one window and do all the operations available in MIDAS for an image.
• All the scales can be plotted in a unique window. Figure 14.13, obtained by the command visual/cube, shows the superposition of the scales in a window.
• In figure 14.14, each scale is plotted in a 3 dimensional representation (command visual/pers).
• In figure 14.15, each scale is binarized and represented by gray level (command visual/synt).
• In figure 14.16, one contour per scale is plotted (command visual/cont).

  

Figure 14.13: Superposition of all the scales. This image is obtained by the command visual/cube.

  

Figure 14.14: Superposition of all the scales. Each scale is plotted in a 3 dimensional representation. This image is obtained by the command visual/pers.

  

Figure 14.15: Synthesis image (command visual/synt). Each scale is binarized, and represented by one gray level.
