sam2

sam2(image, detections)

'sam2' is a tool that can segment multiple objects given an input bounding box, label and score. It returns a set of masks along with the corresponding bounding boxes and labels.

PARAMETER	DESCRIPTION
image	The image that contains multiple instances of the object. TYPE: ndarray
detections	A list of dictionaries containing the score, label, and bounding box of the detected objects with normalized coordinates between 0 and 1 (xmin, ymin, xmax, ymax). xmin and ymin are the coordinates of the top-left and xmax and ymax are the coordinates of the bottom-right of the bounding box. TYPE: List[Dict[str, Any]]

RETURNS	DESCRIPTION
List[Dict[str, Any]]	List[Dict[str, Any]]: A list of dictionaries containing the score, label, bounding box, and mask of the detected objects with normalized coordinates (xmin, ymin, xmax, ymax). xmin and ymin are the coordinates of the top-left and xmax and ymax are the coordinates of the bottom-right of the bounding box. The mask is binary 2D numpy array where 1 indicates the object and 0 indicates the background.

Example

>>> sam2(image, [
        {'score': 0.49, 'label': 'flower', 'bbox': [0.1, 0.11, 0.35, 0.4]},
    ])

DESCRIPTION

List[List[Dict[str, Any]]]

List[List[Dict[str, Any]]]: A list of list of dictionaries containing the label, segmentation mask and bounding boxes. The outer list represents each frame and the inner list is the entities per frame. The detected objects have normalized coordinates between 0 and 1 (xmin, ymin, xmax, ymax). xmin and ymin are the coordinates of the top-left and xmax and ymax are the coordinates of the bottom-right of the bounding box. The mask is binary 2D numpy array where 1 indicates the object and 0 indicates the background. The label names are prefixed with their ID represent the total count.

florence2_object_detection

florence2_object_detection(prompt, image)

'florence2_object_detection' is a tool that can detect multiple objects given a text prompt which can be object names or caption. You can optionally separate the object names in the text with commas. It returns a list of bounding boxes with normalized coordinates, label names and associated confidence scores of 1.0.

PARAMETER	DESCRIPTION
prompt	The prompt to ground to the image. Use exclusive categories that do not overlap such as 'person, car' and NOT 'person, athlete'. TYPE: str
image	The image to used to detect objects TYPE: ndarray

RETURNS	DESCRIPTION
List[Dict[str, Any]]	List[Dict[str, Any]]: A list of dictionaries containing the score, label, and bounding box of the detected objects with normalized coordinates between 0 and 1 (xmin, ymin, xmax, ymax). xmin and ymin are the coordinates of the top-left and xmax and ymax are the coordinates of the bottom-right of the bounding box. The scores are always 1.0 and cannot be thresholded

Example

countgd_object_detection

countgd_object_detection(prompt, image, box_threshold=0.23)

'countgd_object_detection' is a tool that can detect multiple instances of an object given a text prompt. It is particularly useful when trying to detect and count a large number of objects. You can optionally separate object names in the prompt with commas. It returns a list of bounding boxes with normalized coordinates, label names and associated confidence scores.

PARAMETER	DESCRIPTION
prompt	The object that needs to be counted. TYPE: str
image	The image that contains multiple instances of the object. TYPE: ndarray
box_threshold	The threshold for detection. Defaults to 0.23. TYPE: float DEFAULT: 0.23

RETURNS	DESCRIPTION
List[Dict[str, Any]]	List[Dict[str, Any]]: A list of dictionaries containing the score, label, and bounding box of the detected objects with normalized coordinates between 0 and 1 (xmin, ymin, xmax, ymax). xmin and ymin are the coordinates of the top-left and xmax and ymax are the coordinates of the bottom-right of the bounding box.

Example

>>> countgd_object_detection("flower", image)
[
    {'score': 0.49, 'label': 'flower', 'bbox': [0.1, 0.11, 0.35, 0.4]},

DESCRIPTION

List[List[Dict[str, Any]]]

List[List[Dict[str, Any]]]: A list of list of dictionaries containing the label, segmentation mask and bounding boxes.

custom_object_detection

custom_object_detection(
    deployment_id, image, box_threshold=0.1
)

'custom_object_detection' is a tool that can detect instances of an object given a deployment_id of a previously finetuned object detection model. It is particularly useful when trying to detect objects that are not well detected by generalist models. It returns a list of bounding boxes with normalized coordinates, label names and associated confidence scores.

PARAMETER	DESCRIPTION
deployment_id	The id of the finetuned model. TYPE: str
image	The image that contains instances of the object. TYPE: ndarray
box_threshold	The threshold for detection. Defaults to 0.1. TYPE: float DEFAULT: 0.1

RETURNS	DESCRIPTION
List[Dict[str, Any]]	List[Dict[str, Any]]: A list of dictionaries containing the score, label, and bounding box of the detected objects with normalized coordinates between 0 and 1 (xmin, ymin, xmax, ymax). xmin and ymin are the coordinates of the top-left and xmax and ymax are the coordinates of the bottom-right of the bounding box.

Example

>>> custom_object_detection("abcd1234-5678efg", image)
[
    {'score': 0.49, 'label': 'flower', 'bbox': [0.1, 0.11, 0.35, 0.4]},

'glee_sam2_instance_segmentation' is a tool that can detect multiple instances given a text prompt such as object names or referring expressions on images. It's particularly good at detecting specific objects given detailed descriptive prompts. It returns a list of bounding boxes with normalized coordinates, label names, masks and associated probability scores.

PARAMETER	DESCRIPTION
prompt	The object that needs to be counted, only supports a single prompt with no commas or periods. TYPE: str
image	The image that contains multiple instances of the object. TYPE: ndarray

RETURNS	DESCRIPTION
List[Dict[str, Any]]	List[Dict[str, Any]]: A list of dictionaries containing the score, label, bounding box, and mask of the detected objects with normalized coordinates (xmin, ymin, xmax, ymax). xmin and ymin are the coordinates of the top-left and xmax and ymax are the coordinates of the bottom-right of the bounding box. The mask is binary 2D numpy array where 1 indicates the object and 0 indicates the background.

'glee_sam2_video_tracking' is a tool that can track and segment multiple objects in a video given a text prompt such as object names or referring expressions. It's particularly good at detecting specific objects given detailed descriptive prompts and returns a list of bounding boxes, label names, masks and associated probability scores and is useful for tracking and counting without duplicating counts.

PARAMETER	DESCRIPTION
prompt	The prompt to ground to the image, only supports a single prompt with no commas or periods. TYPE: str
frames	The list of frames to ground the prompt to. TYPE: List[ndarray]
chunk_length	The number of frames to re-run agentic object detection to to find new objects. TYPE: Optional[int] DEFAULT: 25

RETURNS

DESCRIPTION

List[List[Dict[str, Any]]]

List[List[Dict[str, Any]]]: A list of list of dictionaries containing the label, segmentation mask and bounding boxes. The outer list represents each frame and the inner list is the entities per frame. The detected objects have normalized coordinates between 0 and 1 (xmin, ymin, xmax, ymax). xmin and ymin are the coordinates of the top-left and xmax and ymax are the coordinates of the bottom-right of the bounding box. The mask is binary 2D numpy array where 1 indicates the object and 0 indicates the background. The label names are prefixed with their ID represent the total count.

Example

heat_map	A dictionary containing the heat map under the key 'heat_map'. TYPE: Dict[str, Any]
alpha	The transparency of the overlay. Defaults to 0.8. TYPE: float DEFAULT: 0.8

RETURNS	DESCRIPTION
ndarray	np.ndarray: The image with the heat map displayed.

Example

>>> image_with_heat_map = overlay_heat_map(
    image,
    {
        'heat_map': array([[0, 0, 0, ..., 0, 0, 0],
