Expand description

Calculates the rotation angle of 2D vectors.

The function cv::phase calculates the rotation angle of each 2D vector that is formed from the corresponding elements of x and y : block formula

The angle estimation accuracy is about 0.3 degrees. When x(I)=y(I)=0 , the corresponding angle(I) is set to 0.

§Parameters

  • x: input floating-point array of x-coordinates of 2D vectors.
  • y: input array of y-coordinates of 2D vectors; it must have the same size and the same type as x.
  • angleInDegrees: when true, the function calculates the angle in degrees, otherwise, they are measured in radians.

§Returns

array of vector angles; it has the same size and same type as x.

§Note

This alternative version of phase function uses the following default values for its arguments:

  • angle_in_degrees: false
