Hi
For example, I have a matrix M of size 10x10 and I have a column matrix ind of length 5
How can I assign A(ind,:) to a new matrix B in OpenCV?
Below is how I do in Matlab:
A = [ 41 8 33 36 22 14 38 43 18 4
46 49 2 2 20 34 13 13 42 3
7 48 43 14 39 33 26 41 30 27
46 25 47 3 40 9 35 13 28 39
32 41 34 5 10 6 45 47 46 47
5 8 38 42 25 25 48 18 15 7
14 22 38 35 23 48 28 10 38 29
28 46 20 16 33 18 7 13 38 24
48 40 33 48 36 30 8 31 20 1
49 48 9 2 38 12 13 24 29 17]
ind = [2; 8; 4; 6; 2]
B = A(ind, :);
B = [ 46 49 2 2 20 34 13 13 42 3
28 46 20 16 33 18 7 13 38 24
46 25 47 3 40 9 35 13 28 39
5 8 38 42 25 25 48 18 15 7
46 49 2 2 20 34 13 13 42 3]
Can anyone tell me how to do this in OpenCV without using for loop
