Gradient

The slope,or change in elevation,of land or improvements such as a pipe or a road.It is expressed as the ratio of inches (or feet) of rise or fall over a specified distance. It is similar to the concept of pitch in roofing.Figure A (above) has a gradient of 1:12 because the grade increases by 1 foot over a distance of 12 feet. Figure B has a gradient of 1:6.

Tremendous progress has been made in the field of surface-bound soft material gradients in recent years, with intriguing new areas of investigation opening up and advances in bioanalytics changing the way high-throughput screening methods are used in the design and discovery of catalysts and new materials.
One way is to calculate on each image channel a modulus of a gradient, and to take the sum or the supremum of the gradients (Meyer, 1992; Angulo and Serra, 2003).
