## Overview

Selects specific tracked objects from a SAM3 tracking session by their index numbers and combines them into a single output mask. This allows you to choose which objects to keep and which to ignore from the tracking results.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| --- | --- | --- | --- | --- |
| `track_data` | The tracking data output from a SAM3 tracker node, containing the packed masks and original image size. | SAM3TRACKDATA | Yes | N/A |
| `object_indices` | Comma-separated object indices to include in the output mask (e.g., '0,2,3'). If left empty, all tracked objects are included. | STRING | No | Any comma-separated list of integers |

## Outputs

| Output Name | Description | Data Type |
| --- | --- | --- |
| `masks` | A single binary mask for each frame, where selected objects are combined into one mask. If no objects are selected or no tracking data exists, returns a zero mask. | MASK |
