Dynamic Zone¶
Version v1¶
The DynamicZoneBlock is a transformer block designed to simplify polygon
so it's geometrically convex and then reduce number of vertices to requested amount.
This block is best suited when Zone needs to be created based on shape of detected object
(i.e. basketball field, road segment, zebra crossing etc.)
Input detections should be filtered and contain only desired classes of interest.
Type identifier¶
Use the following identifier in step "type" field: roboflow_core/dynamic_zone@v1to add the block as
as step in your workflow.
Properties¶
| Name | Type | Description | Refs |
|---|---|---|---|
name |
str |
The unique name of this step.. | ❌ |
required_number_of_vertices |
int |
Keep simplifying polygon until number of vertices matches this number. | ✅ |
The Refs column marks possibility to parametrise the property with dynamic values available
in workflow runtime. See Bindings for more info.
