copy vector of mat to vector of mat
(This is related to this )
I have a vector<Mat> src which is filled with data.
It's size is src.resize( N )
I have another vector<mat> dest; I am declaring it's size to be dest.resize( N )
1) What is the right way to copy src to dest?Just dest=src?
2) If I want to copy to dest ,only the 1st row and all columns of src vector, then what size the dest vector should be?
dest = src;
src[0]( Range(0, 1),Range::all() ).copyTo( dest[0](Range::all(), Range::all() ) ); //for the 1st array of vector
If ,for example src is 4x4 , then ,since I want to keep only 1st row and all columns,the dest size should be 1x4.
Is there a way to do this ?Using the src[0]( Range(0, 1),Range::all() ).copyTo( dest[0](Range::all(), Range::all() ) )?
Or,another idea , is to have the dest the same size with src ,but fill all the rest elements with zero for example?
=====UPDATE================
I figured this:
dest[0] = src[0 ]( Range(0, 1),Range::all() );
for first row and all columns.
( I can't make it an answer yet ,but if there is another way please share )
in your code src and dst are vectors of Mat. Using dest.resize( N ) you are creating N Mats so that src[0], src[1]... src[N] are a Mats that are a matrix of pixel.
I suggest to read a bit of docs about Mat, especially = operator .... in addiction there are tons of things and examples already written to learn, like this and this
@pklab:Ok, thanks.
