Testing model is tensorflow offical model in github repo, please refer https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/tf2_detection_zoo.md to download the detect model as you need. For example, local testing was carried on with 'ssd_mobilenet_v2_coco_2018_03_29.tar.gz', and used one image of dog in https://github.com/tensorflow/models/blob/master/research/object_detection/test_images/image1.jpg Testing command is: ./ffmpeg -i image1.jpg -vf dnn_detect=dnn_backend=tensorflow:input=image_tensor:output=\ "num_detections&detection_scores&detection_classes&detection_boxes":model=ssd_mobilenet_v2_coco.pb,\ showinfo -f null - We will see the result similar as below: [Parsed_showinfo_1 @ 0x33e65f0] side data - detection bounding boxes: [Parsed_showinfo_1 @ 0x33e65f0] source: ssd_mobilenet_v2_coco.pb [Parsed_showinfo_1 @ 0x33e65f0] index: 0, region: (382, 60) -> (1005, 593), label: 18, confidence: 9834/10000. [Parsed_showinfo_1 @ 0x33e65f0] index: 1, region: (12, 8) -> (328, 549), label: 18, confidence: 8555/10000. [Parsed_showinfo_1 @ 0x33e65f0] index: 2, region: (293, 7) -> (682, 458), label: 1, confidence: 8033/10000. [Parsed_showinfo_1 @ 0x33e65f0] index: 3, region: (342, 0) -> (690, 325), label: 1, confidence: 5878/10000. There are two boxes of dog with cores 94.05% & 93.45% and two boxes of person with scores 80.33% & 58.78%. Signed-off-by: Ting Fu <ting.fu@intel.com> Signed-off-by: Guo, Yejun <yejun.guo@intel.com>
