GradientOrientationFilter

GradientOrientationFilter[data, r] gives the local orientation parallel to the gradient of data, computed using discrete derivatives of a Gaussian of pixel radius r, returning values between -π/2 and π/2.

• GradientOrientationFilter[data, {r, σ}] uses a Gaussian with standard deviation σ.

Examples
