How to label skewed images? #54

I have an application of labeling number plates of bikes in which the images are skewed, but we are able to make only rectangular bounding boxes as is allowed to be taken by YOLO . So the area of interest also includes some unwanted regions. Any suggestions on handling such cases? Examples of such cases are attached morning_frames638 morning_frames911

this is, in my opinion... an older style of data annotation. I do not believe VOC in general have skews in their bounding box labels.. You would likely do much better to instead use a more modern data annotation style like COCO... in which each individual pixel is labeled.
