Wavelets (2)

WAVELET
The left column below the original image shows the information that is stored in the layers when the scale settings are initial=1 and step=1 (notation 1/0). The right column shows the image if that specific layer is set 20x enhancement (using the slider).

Compared to the previous page the final image is hardly different, so for this type of lunar images a 1/0 scaling can be the most usefull.

Noise is apparent in the layer. In general layer 1 (if scale=1) is often the layer that contains noise. Keep the layer at 1 or even uncheck the layer.

Hardly any noise can be seen . This layer is the most usefull.

Noise is gone but now the finest details are also slightly lost. This layer is still usefull .

Tthe image got clearly smoother but and lots of detail is lost. The layer is only usefull for the background (large scale) parts.

Probably not much interesting information is left at this layer, leave it at value =1
