Tensorflow Object Detection Api - Visualize Region Proposals

I would like to be able to visualize the regions proposals made by Faster-RCNN (like Resnet101_coco) using Tensorflow Object Detection API, preferably in Tensorboard. Is there any

Solution 1:

You can visualize the detected objects in tensorboard during evaluation (i.e. while running object_detection/eval.py script) You would need to add num_visualizations key to the config file, e.g.

eval_config: {
  num_examples:20000num_visualizations:16min_score_threshold:0.15# Note: The below line limits the evaluation process to 10 evaluations.# Remove the below line to evaluate indefinitely.max_evals:1
}

After running evaluation, you should be able to see an images tab in Tensorboard showing the detected objects. You can adjust the IoU threshold (min_score_threshold) to vary the number of displayed detections.
