[−][src]Function opencv::core::add
pub fn add(
src1: &dyn ToInputArray,
src2: &dyn ToInputArray,
dst: &mut dyn ToOutputArray,
mask: &dyn ToInputArray,
dtype: i32
) -> Result<()>
Calculates the per-element sum of two arrays or an array and a scalar.
The function add calculates:
- Sum of two arrays when both input arrays have the same size and the same number of channels:
- Sum of an array and a scalar when src2 is constructed from Scalar or has the same number of
elements as
src1.channels()
: - Sum of a scalar and an array when src1 is constructed from Scalar or has the same number of
elements as
src2.channels()
: whereI
is a multi-dimensional index of array elements. In case of multi-channel arrays, each channel is processed independently.
The first function in the list above can be replaced with matrix expressions:
dst = src1 + src2; dst += src1; // equivalent to add(dst, src1, dst);
The input arrays and the output array can all have the same or different depths. For example, you can add a 16-bit unsigned array to a 8-bit signed array and store the sum as a 32-bit floating-point array. Depth of the output array is determined by the dtype parameter. In the second and third cases above, as well as in the first case, when src1.depth() == src2.depth(), dtype can be set to the default -1. In this case, the output array will have the same depth as the input array, be it src1, src2 or both.
Note: Saturation is not applied when the output array has the depth CV_32S. You may even get result of an incorrect sign in the case of overflow.
Parameters
- src1: first input array or a scalar.
- src2: second input array or a scalar.
- dst: output array that has the same size and number of channels as the input array(s); the depth is defined by dtype or src1/src2.
- mask: optional operation mask - 8-bit single channel array, that specifies elements of the output array to be changed.
- dtype: optional depth of the output array (see the discussion below).
