OpenCV lacks a conversion function from rotation matrix to quaternion. In ROS applications, the rotation of a robot or link is generally described by 4 quaternion numbers. Some people might say that you have "tf" for all such transformations, but it requires your data to be of specific datatype. Here is a small function, that converts opencv Mat…
void getQuaternion(Mat R, double Q[])
{
double trace = R.at<double>(0,0) + R.at<double>(1,1) + R.at<double>(2,2);
if (trace > 0.0)
{
double s = sqrt(trace + 1.0);
Q[3] = (s * 0.5);
s = 0.5 / s;
Q[0] = ((R.at<double>(2,1) - R.at<double>(1,2)) * s);

# arguement required.
# Pre-requisites: 1. Format the dataset as explained by deboc
# 2. create the Imageset text file using 'ls Annotations/ -m | sed s/\\s/\\n/g | sed s/.xml//g | sed s/,//g > ImageSets/train.txt'
# 1st arguement = Imageset file name Example: train.txt
# 2nd arguement = path to custom dataset Example: ~/py-faster-rcnn/data/VOC_devkit/
# Using Instructions
# $ python discard_shuffle_data.py [arg1] [arg2]
