Description

VOC and ImageNet use the same xml annotation format. Although they are most famous computer vision dataset. The annotation format is not supported in OpenCV. Some reasons for crash includes:

1. The VOC annotation format don't start with ' <opencv_storage>'.
2. Some values, e.g. <owner><flickrid>, might contains characters not supported.
3. Values like <filename>000005.jpg</filename> needs to be changed to <filename>"000005.jpg"</filename> in order to avoid crash in reading.

Above problems can be avoid by some simple pre-processing. The other bug, which is reported by OpenCV as "Duplicated key", can't be easily addressed. However, each VOC image has several <object> key.
