image_info
, shape: [1x3], format: [BxC], where:detection_classes
. Contains predicted bounding boxes classes in a range [1, 91]. The model was trained on the Microsoft* COCO dataset version with 91 categories of object, 0 class is for background. Mapping to class names provided in <omz_dir>/data/dataset_classes/coco_91cl_bkgr.txt
file.detection_scores
. Contains probability of detected bounding boxes.detection_boxes
. Contains detection boxes coordinates in format [y_min, x_min, y_max, x_max]
, where (x_min
, y_min
) are coordinates of the top left corner, (x_max
, y_max
) are coordinates of the right bottom corner. Coordinates are rescaled to input image size.num_detections
. Contains the number of predicted detection boxes.The array of summary detection information, name: reshape_do_2d
, shape: [1, 1, N, 7], where N is the number of detected bounding boxes. 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 the image in the batchlabel
- predicted class ID, in range [1, 91], mapping to class names provided in <omz_dir>/data/dataset_classes/coco_91cl_bkgr.txt
fileconf
- confidence for the predicted classx_min
, y_min
) - coordinates of the top left bounding box corner (coordinates stored in normalized format, in range [0, 1])x_max
, y_max
) - coordinates of the bottom right bounding box corner (coordinates stored in normalized format, in range [0, 1])You can download models and if necessary convert them into Inference Engine format using the Model Downloader and other automation tools as shown in the examples below.
