Visualisation of the second class

Five visualisation tools are available in MIDAS for pyramidal wavelet transform.

• 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. Scales are interpolated in order to have the same size as the image.
• All the scales can be plotted in a unique window. The figure 14.17, obtained by the command visual/cube, shows the superposition of the scales in a window.
• In figure 14.18, each scale is plotted in a 3 dimensional representation (command visual/pers).
• In figure 14.19, all the scales are represented in an image which is 2 times bigger than the original one (command visual/synt).
• By interpolating each scale to the size of the original image, a plot similar to figure 14.16 can be obtained ( command visual/cont).
