Ripple mark, one of a series of small marine, lake, or riverine topographic features, consisting of repeating wavelike forms with symmetrical slopes, sharp peaks, and rounded troughs.
Some barrier reefs are more or less circular, surrounding an island, but larger barrier reefs, such as those along the Red Sea coast and Australia's Great Barrier Reef, are complex linear features consisting of chains of reef patches, some of them elongated into ribbon reefs.
Features consisting of a time-series average of observed concentrations produce localization accuracy similar to when maximum concentration features are used.
The 63 tatum features consisting of,,,,,, and the tatum vector with 57 elements constitute the first part of the rhythmic feature set.
Moreover, spatial features consisting of edge information and pixel distortion have been used to predict quality of JPEG2000 encoded images in[114].
Additionally, we used the first derivatives of the features, resulting in six-dimensional features consisting of Δ x,Δ y,z,Δ Δ x,Δ Δ y, and Δ z.
