Image transpose example canvas elements named canvasinput and canvasoutput have been prepared.
An image will be created.
0 to 255 for cv 8u images.
Moreover at transpose gives you more control over how you wish to swap the axes such that the overall permutation is faster.
The class mat represents an n dimensional dense numerical single channel or multi channel array.

What about the vice versa.
For example if a 3 2 is 1 2i and b a then the element b 2 3 is also 1 2i.
Transpose image is used to transpose the given input image as shown in the output in the below part.
And then transpose the image.
B a returns the nonconjugate transpose of a that is interchanges the row and column index for each element if a contains complex elements then a does not affect the sign of the imaginary parts.
