Detailed Description

Superclass for gradient estimation.

vtkEncodedGradientEstimator is an abstract superclass for gradient estimation. It takes a scalar input of vtkImageData, computes a gradient value for every point, and encodes this value into a three byte value (2 for direction, 1 for magnitude) using the vtkDirectionEncoder. The direction encoder is defaulted to a vtkRecursiveSphereDirectionEncoder, but can be overridden with the SetDirectionEncoder method. The scale and the bias values for the gradient magnitude are used to convert it into a one byte value according to v = m*scale + bias where m is the magnitude and v is the resulting one byte value.
