Get Max Cv Mat

C abs a b is equivalent to absdiff a b c.

Get max cv mat.

The signature of the comparison function should be equivalent to the following. Calculates an absolute value of each matrix element. Consider we have a matrix our task is to find the maximum element of each column of that matrix and print them. Setting and getting pixel values of a gray image in c.

For example if a is a matrix then max a 1 2 computes the maximum over all elements in a since every element of a matrix is contained in the array slice defined by dimensions 1 and 2.

Abs is a meta function that is expanded to one of absdiff or convertscaleabs forms. It can be used to store real or complex valued vectors and matrices grayscale or color images voxel volumes vector fields point clouds tensors histograms though very high dimensional histograms may be better stored in a sparsemat.

But it has more applications for convolution operation zero padding etc. For each column reset the max and find the max element and print it. A b the values to compare ilist initializer list with the values to compare comp comparison function object i e. 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.

The class mat represents an n dimensional dense numerical single channel or multi channel array. Making borders for images padding if you want to create a border around the image something like a photo frame you can use cv copymakeborder function. C abs a is equivalent to absdiff a scalar all 0 c. M max a vecdim computes the maximum over the dimensions specified in the vector vecdim.

Note don t forget to delete cv mat cv matvector and r the mat you get from matvector when you don t want to use them any more.
