Preparing a custom dataset

[avi-jain]

Hello, I'm a little confused by the ymin - float array, the top left corner of the bounding boxes; normalized coordinates and ymax - a float array, the top edge of the bounding boxes; normalized coordinates; specifications. I currently have my annotations for each image in the YOLO model format (class_number box1_x1_ratio box1_y1_ratio box1_width_ratio box1_height_ratio) as well as in (box1_x1 box1_y1 box1_width box1_height) format. I plan on writing a script to convert these to the desired format by Multibox. Could you please tell what would be the required changes? Thanks
