Normalized Amplitude is computed as the cosine of instantaneous phase angle. This attribute has all of the details of instantaneous phase while avoiding the jumps inherent in it. The attribute has no amplitude information and its values vary between –1 and +1.
- It represents continuity and is helpful in lateral continuity direction determination.
- It will have no amplitude information
This attribute has most of its values at +1 and -1 and as mentioned does not contain the original amplitude information. Colorbars that emphasize the endpoints and the zero-crossing line work best for this attribute similar to some of the edge detection attributes.
