Slowness principle
WebbThe seismic ray at any given point follows the direction of the gradient of the traveltime field . As before, let u be the unit vector along the ray. The ray in general will follow a curved path, and the raypath vector will be tangent to this curved raypath. Let us derive the ray equation. This equation tells us how the raypath vector changes ... WebbThe slowness principle is based on the observation that the environment, sen-sory signals, and internal representations of the environment vary on different time scales. The environment, 1 An early description of the principle was given by Hinton (1989) (p. 208) and early models based on temporal slowness

The arrival of this pulse is detected at an array of receivers a few feet from the transmitter. The difference in time elapsed between the arrival of sound at the receivers is the desired travel time, the sound wave travels through the formation while ... WebbThe slowness principle is a hypothesis for the functional organization of the visual cortex and possibly other sensory areas of the brain (Wiskott et al. 2011) and it has been introduced as a way to model the transformation invariance in natural image sequences (Zhang Zhang and Dacheng Tao 2012).

In the case of vision, one adaptation principle that has been put forward is the so-called slowness principle. However, the visual system is partially structured even before eye opening, …
