Examples:

REST API:

WIP

Configuration File:

Only allow person detections:

```yaml
source:
- address: videos/sd_london_station_sd.mp4
  type: file
elements:
- name: infer
  args:
    model: coco-nano
    score_threshold: 0.3
    iou_threshold: 0.3
- name: filter-item
  args:
    labels: [person]
```

Only allow person and bus detections:

```yaml
source:
- address: videos/sd_london_station_sd.mp4
  type: file
elements:
- name: infer
  args:
    model: coco-nano
    score_threshold: 0.3
    iou_threshold: 0.3
- name: filter-item
  args:
    labels: [person, bus]
```

FilterItem Objects

class FilterItem(Element)

Filter out detections that are not part of a user-defined list of labels.

Attributes:

Examples:

Face:

```python
ele = FilterItem(["face"])
```

Person:

```python
ele = FilterItem(["person"])
```

process

def process(meta: PipelineMetadata)

Filter out detections that are not part of a user-defined list of items.

This is the main function for this element. It filters out detections that are not part of a user-defined list of items. If the list of items is empty then it will keep all detections.

Arguments:

• meta PipelineMetadata - The metadata to process.

Returns:

• meta PipelineMetadata - The processed metadata.

Examples:

```python
meta = FilterItem(["person"]).process(meta)
```
