Detected Objects Transform

Overview

Detected Objects Transform node post-processes rectangular detections with NMS, containment-based relabeling, and label remapping — without running a detector.

Use this node after Object Detection, General Object Detection, or similar detectors when you need to merge contained objects, rename labels, or re-apply NMS on an existing detection list.

Input

Detected Objects

array required

List of detected objects to transform. Each object must include Bounding Box (bbox: [x, y, width, height]) and Label.

Overlap threshold

number required advanced

NMS overlap threshold (higher allows more overlap). See Overlap threshold for tuning guidance.

Range: 0.0 to 1.0
Default: 0.5

Class-agnostic NMS

boolean required advanced

When enabled, NMS is applied across all classes. When disabled, NMS runs per class and NMS Class Group mappings can appear (Class Label + Group ID; labels may use regular expressions).

Default: true

Transform contains

array required

Configurations for transforming objects based on contained items. Each entry can include:

• Primary object label
• Combine Type — ALL_OF (default), ANY_OF, NONE_OF
• Contained object labels (regex allowed; max 10)
• Position to compare — TOTAL, TOP, CENTER (default), BOTTOM
• New object label
• Detected label information from — PRIMARY (default) or CONTAINED_FIRST
• Handling of original bounding boxes — KEEP_ALL, KEEP_PRIMARY, KEEP_CONTAINED, REMOVE_ALL (default)

Default: []

Transform labels

array required

Mappings from original label names (Key) to transformed names (Value). Keys may use regular expressions. Maximum 100 entries.

Default: []

Output

Detected Count

integer

Number of objects after transformation.

Detected Objects

array

Transformed detection objects with:

• Bounding Box (bbox): [x, y, width, height]
• Label
• Confidence
