kandi X-RAY | object_tracking Summary
This repo contains C++ examples to use the following object trackers:. Also, there is another tracker that I implemented for ARM CPUs. It extracts FAST keypoints from the detected object, tracks them by KLT algorithm, and maps the bounding box to a new box using the estimated similarity transformation between the points. In addition to being multi-scale, all the trackers would report failures when the object is no longer in the scene or the tracking quality is below a threshold. This makes them very applicable to real-world projects. Feel free to use and send me PRs if you found better trackers :).

I know how to trigger a video intelligence request for object tracking / object detection with Google Cloud as following :
...ANSWER
Answered 2021-Jan-25 at 10:34To trigger the same function for brand detection (LOGO_RECOGNITION?), scene detection (SHOT_CHANGE_DETECTION?), TEXT_DETECTION and SPEECH_TRANSCRIPTION, you can replace OBJECT_TRACKING by, respectively, LOGO_RECOGNITION, SHOT_CHANGE_DETECTION, TEXT_DETECTION or SPEECH_TRANSCRIPTION.

QUESTION
I'm trying to run object tracking on a folder containing multiple videos. There are 5 videos in my bucket and following the documentation from here, it suggests using the wildcard (*) operator. However, when I run the entire script, only 1 video gets annotated and not the entire folder containing 5 videos. Also, response2.json does not get created as the output_uri in my GCS bucket.
To identify multiple videos, a video URI may include wildcards in the object-id. Supported wildcards: ' * ' to match 0 or more characters; ‘?’ to match 1 character. https://googleapis.dev/python/videointelligence/latest/gapic/v1/types.html
Which is what I've done in my input_uri bit of the code:
...ANSWER
Answered 2020-Oct-16 at 21:12please modify 'gcs_uri = 'gs://video_intel/'' to gcs_uri = 'gs://video_intel/.*'
QUESTION
I'm trying to use below Python documentation to use the OBJECT_TRACKING METHOD. The script works but I'm wondering how can I download the JSON. I'm just starting out in Python.
Note: This question has now been answered by Javier below. I have amended the script below to show the answer for others looking for a same solution. There is an output_uri variable and in the operation function, the output_uri parameter has been added to create a response.json in your GCS location declared earlier.
...ANSWER
Answered 2020-Oct-05 at 06:58In the documentation of the annotate_video method you can find there's a parameter called output_uri you can use for this purpose:
output_uri (str) – Optional. Location where the output (in JSON format) should be stored. Currently, only Google Cloud Storage URIs are supported, which must be specified in the following format: gs://bucket-id/object-id (other URI formats return google.rpc.Code.INVALID_ARGUMENT). For more information, see Request URIs.
QUESTION
I have been using Google Cloud Video Intelligence annotation functionality with Google App Engine Flex. When I try to use VideoIntelligence with a two hour video, it takes 60 minutes for the AnnotateVideo function to respond.
...ANSWER
Answered 2020-May-06 at 16:14Cloud Run’s 900 second timeout is subject to change soon to satisfy your needs (up to an hour). There's a feature in the works. I’ll update here once it's available in beta, stay tuned.

QUESTION
I have been using Google Cloud Video Intelligence succesfully with my content with the following code for some time with my Django application running on Google App Engine Flex.
...ANSWER
Answered 2020-Apr-20 at 12:11There is no way for you to make this automatically by relying on an API. You would need to keep track of the amount of minutes you have using and deduct them from the free minutes so that you send yourself a notification.
Additionally, you can do the estimate of one of your cases with the GCP Pricing calculator.
