FLEX AI Setup and Use Guide, FLEX AI enables you to enhance camera capabilities, enabling them to detect and track previously unidentifiable objects. While many cameras can detect and track people and specific vehicle types, it is a different matter identifying shopping carts, forklift trucks, hovercrafts, or items on a conveyor belt.

FLEX AI: Get started

Summary:

FLEX AI enables you to enhance camera capabilities, enabling them to detect and track previously unidentifiable objects. While many cameras can detect and track people and specific vehicle types, it is a different matter identifying shopping carts, forklift trucks, hovercrafts, or items on a conveyor belt.

With FLEX AI you can create custom object detection models for solid objects that can then be deployed to cameras, enabling you to detect objects that standard analytics does not already detect.

It is a cloud-based application, and its results are compatible with deployment to P-series AI cameras.

How it Works:

FLEX AI operates on a subscription-based model, granting users comprehensive access to train, process, and download custom detection models for end customers. However, the allocation of licenses requires a careful consideration of each end customer, with a separate FLEX AI license needed for each one. This process is typically managed by a STEP Partner, who oversees the distribution of licenses to ensure effective deployment.

For actual deployment onto cameras, FLEX AI uses a perpetual licensing system, distinct from its subscription model. Each camera necessitates its own perpetual license to run FLEX AI models effectively. This approach ensures that users can deploy and utilize the models on their cameras without the constraints of a subscription-based licensing system.

In terms of training models, FLEX AI currently supports the MP4 format or tagged WAVE Sync videos for training.

NOTE: Each project can only train one model.

Camera Compatibility:

Refer to the following article: Which Cameras are Compatible With FLEX AI

Note: Each camera can only run one FLEX AI model, although it may run in parallel with WiseAI.

FLEX AI: How do I annotate objects?

Summary:

This article describes how to move through a training video and mark objects. The goal is to take a video clip and pause at several points in the video and annotate objects (draw boxes around) you are teaching FLEX AI to detect.

Step By Step Guide:

Annotating objects

1. Pause the video on any frame that contains the object of interest.

2. Draw a detection box around every instance of the object. There can be multiple instances of an object and each instance should have its own detection box.

3. Click the Tighten button (or the keyboard shortcut T) to resize the detection boxes.
This means you can save time by roughly drawing the boxes and then tightening.

Step 1: Roughly draw a box around the object
Step 2: Click the Tighten button (or press T) to quickly get you close
There will be times that FLEX AI does not properly capture the true edges of the object, that’s why the application allows you to readjust the edges of the box. Step 3: Drag the edges/corners of a detection box to finely edit.

4. To remove a detection box, select the appropriate box and click the Delete key on your keyboard.

5. Click Save (or the keyboard shortcut S) to save the marked detection boxes.

6. Once you have drawn the necessary detection boxes, click the Train button. Your project will be unavailable during the training period which typically takes 15 to 30 minutes depending on the number of annotations.

NOTE: Since training is done in the cloud, you can work on any number of other projects
while a project is training.
.

NOTE: The blue detection boxes also appear in the This Frame’s Detections area after you
save. It is recommended that a minimum of 50 detection boxes be defined before your
initial object training is complete. An AI model can include detection boxes from
multiple video clips.

Keyboard shortcuts

You can save time and effort when navigating video, marking, tightening and saving annotations, by using the keyboard shortcuts below.

FLEX AI: How do I improve my object detection model?

Summary:

This article covers improving the AI Object Detection model of your uploaded videos. This process will result in more accurate detections, fewer false positives, and fewer false negatives.

Step By Step Guide:

To improve the AI Object Detection model:

1.Click the Improve button (towards the top right of the video player) after you have reviewed the latest model.
