[−][src]Function opencv::core::phase

pub fn phase(
    x: &dyn ToInputArray, 
    y: &dyn ToInputArray, 
    angle: &mut dyn ToOutputArray, 
    angle_in_degrees: bool
) -> Result<()>

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.
angle: output array of vector angles; it has the same size and same type as x .
angleInDegrees: when true, the function calculates the angle in degrees, otherwise, they are measured in radians.
