about min_gt_height #16

Hi @zhaoweicai

In the configuration of image_gt_data_layer, you define the min_gt_height, which is 25 for cars in KITTI when images resized to 384 * 1280. But I find that there are about 3000 cars with height smaller than 25 which are not labeled with "DontCare" or largely occluded and truncated. Why you ignore those cars?

At first, since the minimum height for evaluation is 25, we only use training instances with height higher than 25. Secondly, the minimum height of 25 in training is after image resizing. For those instances with height lower than 25, they could be used during training when their heights are higher than 25 after random image resizing.
