C++ OpenCV cv::transpose()



---------------------------------------------------------------------------------------------------------------
Description::
This is a C++ program to show the use of transpose funtion which is inbuilt in the opencv library. Transpose function takes 2 parametres. FIrst is mat object for input image and second is mat object of another desired output transposed image. Transpose image is used to transpose the given input image as shown in the output in the below part.
---------------------------------------------------------------------------------------------------------------
Program::

#include <opencv2/opencv.hpp>
using namespace cv;

int main( int argc, char** argv )
{
  char* ImageFile = argv[1];   //image file 
Mat image; image = imread( imageName, IMREAD_COLOR ); //reading file 
if( argc != 2 || !image.data ) { printf( " No image data \n " ); return -1; } Mat transposed_image; //Mat object for storing data transpose(image,transposed_image); //transposing given input image imwrite( "/home/crmgogo/Pictures/transposed_image.jpg", transposed_image ); //Saving images namedWindow( imageName, WINDOW_NORMAL ); namedWindow( "transposed_image", WINDOW_NORMAL ); imshow( imageName, image ); //show windows imshow( "transposed_image", transposed_image ); waitKey(0); return 0; }

---------------------------------------------------------------------------------------------------------------
Commands to run program on terminal::
g++ -ggdb `pkg-config --cflags filename` -o `basename filename .cpp` filename `pkg-config --libs opencv`

$ ./cvopen filename
---------------------------------------------------------------------------------------------------------------
Output::
