Gradient. In the one-dimensional case, a step edge corresponds to a local peak in the first derivative of the intensity function. In the two-dimensional case, we analyze the gradient instead of the first derivative.
Gradient. A gradient describes the slope of a line. The gradient of a straight line is constant . But on a curve the gradient is different at different points on the curve. The G radient F unction. A gradient function describes the gradient of a graph.
Uniform motion. The following symbols will be used throughout M1:. Displacement (distance). Initial velocity. Consider a velocity-time graph of an object moving with these variables:. Final velocity. Acceleration. Now consider the gradient and area under the line. Time.
