Function phase

pub fn phase(
    x: &impl GMatTraitConst,
    y: &impl GMatTraitConst,
    angle_in_degrees: bool,
) -> Result<GMat>

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 :

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.

C++ default parameters

• angle_in_degrees: false
