https://api.pixlab.io/facelandmarks

Get Your API Key & Try FACELANDMARKS Now ↗

Description

Utilize the FACELANDMARKS API endpoint to detect and extract facial landmarks, along with their corresponding rectangle coordinates. This functionality can be integrated with other API endpoints, including CROP, MOGRIFY, and MERGE, to facilitate advanced face processing. The output will include the rectangle coordinates and extracted facial shapes for each detected face. Several complementary API endpoints are available, such as crop for face extraction, drawrectangles for face annotation, and mogrify for content redaction.

HTTP Methods

GET, POST

HTTP Parameters

Required

Fields	Type	Description
`img`	URL	Input media URL. If you want to upload your image directly from your app, then submit a `multipart/form-data` POST request.
`key`	String	Your PixLab API Key ↗. You can also embed your key in the `WWW-Authenticate:` HTTP header and omit this parameter if you want to.

POST Request Body

If you plan to use POST instead of a simple GET request:

Allowed Content-Types:

multipart/form-data
application/json

Use multipart/form-data if you want to upload your media file directly (refer to the REST API code samples or The PixLab Github Repository↗ for a working example). If you are using JSON, then the media file must be already uploaded somewhere. Call store if you want to upload an image before invoking this endpoint.

HTTP Response

application/json.

This command always return a JSON object after each call. The field of interest here is the faces array which hold the rectangle & landmarks coordinates for each detected face. The following are the JSON fields returned in response body:

Fields	Type	Description
status	Integer	Status code 200 indicates success, any other code indicates failure.
faces	Array	JSON array holding the rectangle & landmarks coordinates (See below for fields).
error	String	Error message if `status` != 200.

The following are the object fields returned for each detected face in the faces array defined above:

Fields	Type	Description
rectangle	Array	JSON array holding the rectangle coordinates for this face (See below).
landmarks	Array	JSON array holding the landmarks coordinates for this face (See below).

The following are the object fields returned in each rectangle array, member of the faces array defined above:

Fields	Type	Description
face_id	Integer	Detected face ID.
left	Integer	Rectangle left coordinate: X.
top	Integer	Rectangle top coordinate: Y.
width	Integer	Rectangle width.
height	Integer	Rectangle height.

The following are the object fields returned in each landmarks array, member of the faces array defined above:

Fields	Type	Description
nose	Array	Nose Tip coordinates in the form [x: `Integer`, y: `Integer`].
nose_bottom_left	Array	Nose bottom left coordinates in the form [x: `Integer`, y: `Integer`].
nose_bottom_right	Array	Nose bottom right coordinates in the form [x: `Integer`, y: `Integer`].
mouth_left	Array	left most coordinates of the mouth in the form [x: `Integer`, y: `Integer`].
mouth_right	Array	Right most coordinates of the mouth in the form [x: `Integer`, y: `Integer`].
bottom_lip	Array	Bottom Lip coordinates in the form [x: `Integer`, y: `Integer`].
top_lip	Array	Top Lip coordinates in the form [x: `Integer`, y: `Integer`].
chin	Array	Chin coordinates in the form [x: `Integer`, y: `Integer`].
eye	Array	Array holding the coordinates of the region surrounding the eyes. These includes: pupil_left: Left Pupil coordinates in the form [x: `Integer`, y: `Integer`]. pupil_right: Right Pupil coordinates in the form [x: `Integer`, y: `Integer`]. left_brow_inner: Left Eye Brow Inner coordinates in the form [x: `Integer`, y: `Integer`]. left_brow_outer: Left Eye Brow Outer coordinates in the form [x: `Integer`, y: `Integer`]. right_brow_inner: Right Eye Brow Inner coordinates in the form [x: `Integer`, y: `Integer`]. right_brow_outer: Right Eye Brow Outer coordinates in the form [x: `Integer`, y: `Integer`]. left_inner: Left Eye Inner coordinates in the form [x: `Integer`, y: `Integer`]. left_outer: Left Eye Outer coordinates in the form [x: `Integer`, y: `Integer`]. right_inner: Right Eyer Inner coordinates in the form [x: `Integer`, y: `Integer`]. right_outer: Right Eyer Outer coordinates in the form [x: `Integer`, y: `Integer`].
bone	Array	Array holding the coordinates of some regions of the bone. These includes: center: Bone Center coordinates in the form [x: `Integer`, y: `Integer`]. outer_left: Coordinates of Left most region of the bone in the form [x: `Integer`, y: `Integer`]. outer_right: Coordinates of Right most region of the bone in the form [x: `Integer`, y: `Integer`].

For additional processing, feel free to adjust these coordinates for the next command such as crop for face extraction, drawrectangles for marking faces, mogrify and merge to mimic the Snapchat filters effects (refer to the REST API code samples for a concrete example).

If you need additional landmarks coordinates, please fill an API feature request ticket from the support tab of your dashboard ↗.
