Detailed Description

Matrix expression representation This is a list of implemented matrix operations that can be combined in arbitrary complex expressions (here A, B stand for matrices ( cv::Mat ), s for a cv::Scalar, alpha for a real-valued scalar ( double )):

• Addition, subtraction, negation: A+B, A-B, A+s, A-s, s+A, s-A, -A
• Scaling: A*alpha
• Per-element multiplication and division: A.mul(B), A/B, alpha/A
• Matrix multiplication: A*B
• Transposition: A.t() (means A^T)
• Matrix inversion and pseudo-inversion, solving linear systems and least-squares problems: A.inv([method]) (~ A^-1), A.inv([method])*B (~ X: AX=B)
• Comparison: A cmpop B, A cmpop alpha, alpha cmpop A, where cmpop is one of >, >=, ==, !=, <=, <. The result of comparison is an 8-bit single channel mask whose elements are set to 255 (if the particular element or pair of elements satisfy the condition) or 0.
• Bitwise logical operations: A logicop B, A logicop s, s logicop A, ~A, where logicop is one of &, |, ^.
• Element-wise minimum and maximum: cv::min(A, B), cv::min(A, alpha), cv::max(A, B), cv::max(A, alpha)
• Element-wise absolute value: cv::abs(A)
• Cross-product, dot-product: A.cross(B), A.dot(B)
• Any function of matrix or matrices and scalars that returns a matrix or a scalar, such as cv::norm, cv::mean, cv::sum, cv::countNonZero, cv::trace, cv::determinant, cv::repeat, and others.
• Matrix initializers ( Mat::eye(), Mat::zeros(), Mat::ones() ), matrix comma-separated initializers, matrix constructors and operators that extract sub-matrices (see cv::Mat description).
• Mat_<destination_type>() constructors to cast the result to the proper type.

  Note

  Comma-separated initializers and probably some other operations may require additional explicit Mat() or Mat_<T>() constructor calls to resolve a possible ambiguity.

  Here are examples of matrix expressions:

  // compute pseudo-inverse of A, equivalent to A.inv(DECOMP_SVD)
  SVD svd(A);
  Mat pinvA = svd.vt.t()*Mat::diag(1./svd.w)*svd.u.t();
   
  // compute the new vector of parameters in the Levenberg-Marquardt algorithm
  x -= (A.t()*A + lambda*Mat::eye(A.cols,A.cols,A.type())).inv(DECOMP_CHOLESKY)*(A.t()*err);
   
  // sharpen image using "unsharp mask" algorithm
  Mat blurred; double sigma = 1, threshold = 5, amount = 1;
  GaussianBlur(img, blurred, Size(), sigma, sigma);
  Mat lowContrastMask = abs(img - blurred) < threshold;
  Mat sharpened = img*(1+amount) + blurred*(-amount);
  img.copyTo(sharpened, lowContrastMask);

abs() [1/2]

MatExpr abs ( const Mat & m )

related

Calculates an absolute value of each matrix element.

abs is a meta-function that is expanded to one of absdiff or convertScaleAbs forms:

• C = abs(A-B) is equivalent to absdiff(A, B, C)
• C = abs(A) is equivalent to absdiff(A, Scalar::all(0), C)
• C = Mat_<Vec<uchar,n> >(abs(A*alpha + beta)) is equivalent to convertScaleAbs(A, C, alpha, beta)

The output matrix has the same size and the same type as the input one except for the last case, where C is depth=CV_8U .

Parameters

m

matrix.
