detection_classes
, contains predicted bounding boxes classes in range [1, 91]. The model was trained on Microsoft* COCO dataset version with 90 categories of object.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 top left corner, (x_max
, y_max
) are coordinates 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 - detection_out
, shape - [1x1xNx7]
, 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 IDconf
- confidence for the predicted classx_min
, y_min
) - coordinates of the top left bounding box corner (coordinates are in normalized format, in range [0, 1])x_max
