:param src2: second input array or a scalar.
+ :param src: single input array.
+
+ :param value: scalar value.
+
:param dst: output array that has the same size and type as input arrays.
The function ``absdiff`` calculates:
:param src2: second input array or a scalar.
+ :param src: single input array.
+
+ :param value: scalar value.
+
:param 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``.
:param mask: optional operation mask – 8-bit single channel array, that specifies elements of the output array to be changed.
:param src2: second input array or a scalar.
+ :param src: single input array.
+
+ :param value: scalar value.
+
:param dst: output array that has the same size and type as the input arrays.
:param mask: optional operation mask, 8-bit single channel array, that specifies elements of the output array to be changed.
:param src2: second input array or a scalar.
+ :param src: single input array.
+
+ :param value: scalar value.
+
:param dst: output array that has the same size and type as the input arrays.
:param mask: optional operation mask, 8-bit single channel array, that specifies elements of the output array to be changed.
:param src2: second input array or a scalar.
+ :param src: single input array.
+
+ :param value: scalar value.
+
:param dst: output array that has the same size and type as the input arrays.
:param mask: optional operation mask, 8-bit single channel array, that specifies elements of the output array to be changed.
:param covar: output covariance matrix of the type ``ctype`` and square size.
+ :param ctype: type of the matrixl; it equals 'CV_64F' by default.
+
+ :param cov_mat: output covariance matrix (specific to C syntax).
+
:param mean: input or output (depending on the flags) array as the average value of the input vectors.
+ :param vects: a set of vectors.
+
:param flags: operation flags as a combination of the following values:
* **CV_COVAR_SCRAMBLED** The output covariance matrix is calculated as:
:param angleInDegrees: a flag, indicating whether the angles are measured in radians (which is by default), or in degrees.
+ :param angle_in_degrees: a flag, indicating whether the angles are measured in radians, or in degrees (specific to C syntax).
+
The function ``cartToPolar`` calculates either the magnitude, angle, or both for every 2D vector (x(I),y(I)):
.. math::
:param src2: second input array or a scalar (in the case of ``cvCmp`` and ``cv.Cmp`` it is always an array; in the case of ``cvCmpS``, ``cv.CmpS`` it is always a scalar); when it is an array, it must have a single channel.
+ :param src: single input array.
+
+ :param value: scalar value.
+
:param dst: output array that has the same size as the input arrays and type= ``CV_8UC1`` .
:param cmpop: a flag, that specifies correspondence between the arrays:
* **CMP_LE** ``src1`` is less than or equal to ``src2``.
* **CMP_NE** ``src1`` is unequal to ``src2``.
+ :param cmp_op: a flag, that specifies correspondence between the arrays (specific to C syntax; for possible values see 'cmpop above).

The function compares:
