Circle Visualization

Draw a circle around a detected region in an image.

About this block

The Circle Visualization block lets you draw a circle around detected regions in an image.

This block works with:

• Object detection models

• Segmentation models

The Label Visualization block.

This block only shows circles calculated using the coordinates from an object detection or segmentation model. To see object labels, you will need to add a Label Visualization.

What you can send into this block

To use this block, you need:

1. An input image or video frame, and;

2. Predictions from an Object Detection or Segmentation model.

What this block returns

The Circle Visualization block returns an image with a circle drawn around detected regions in an image.

Here is an example output from this block:

Circles from detected regions displayed on an image.

Here is an example when this block is used with a Label Visualization block:

Circles and labels from an object detection model displayed on an image.

Use cases

This block is useful if you want to see the results from a model on an image. This is common during testing.

Because visualizing predictions adds a small amount of overhead to running a Workflow, we only recommend adding a Visualization in production if you need to see the location of results from your model.
