Function ft1_2d_polynomial 

pub fn ft1_2d_polynomial(
    matrix: &impl ToInputArray,
    kernel: &impl ToInputArray,
    c00: &mut impl ToOutputArray,
    c10: &mut impl ToOutputArray,
    c01: &mut impl ToOutputArray,
    components: &mut impl ToOutputArray,
    mask: &impl ToInputArray,
) -> Result<()>

Computes elements of -transform components.

Parameters

• matrix: Input array.
• kernel: Kernel used for processing. Function ft::createKernel can be used.
• c00: Elements represent average color.
• c10: Elements represent average vertical gradient.
• c01: Elements represent average horizontal gradient.
• components: Output 32-bit float array for the components.
• mask: Mask can be used for unwanted area marking.

The function computes components and its elements using predefined kernel and mask.

C++ default parameters

• mask: noArray()
