Inputs

  1. name: data , shape: [1x3x544x992] - An input image in following format [1xCxHxW]. The expected channel order is BGR.
  2. name: im_info, shape: [1x6] - An image information [544, 992, 992/frame_width, 544/frame_height, 992/frame_width, 544/frame_height]

Outputs

  1. The net outputs "detection_ouput" blob with shape: [1x1xNx7], where N is the number of detected pedestrians. For each detection, the description has the format: [image_id, label, conf, x_min, y_min, x_max, y_max], where:
    • image_id - ID of image in batch
    • label - ID of predicted class
    • conf - Confidence for the predicted class
    • (x_min, y_min) - Coordinates of the top left bounding box corner
    • (x_max, y_max) - Coordinates of the bottom right bounding box corner.
