Face Detection - Algorithm by dlib

No algorithm description given

Introduction This algorithm detects human faces in given images. Works best with forward facing faces. Input (Required): Image URL (http(s) url or dataAPI url) (Optional): Detected faces image save location Output Image URL Detected faces coordinates Detected faces image (if save location given) Example(s) Example 1. Parameter 1: Image URL {
 "images": [
 {
 "url": "https://en.wikipedia.org/wiki/Barack_Obama#/media/File:DIG13623-230.jpg"
 }
 ]
} Output: {
 "images": [
 {
 "detected_faces": [
 {
 "bottom": 1704,
 "left": 1882,
 "right": 2203,
 "top": 1383
 },
 {
 "bottom": 1660,
 "left": 632,
 "right": 1017,
 "top": 1274
 }
 ],
 "url": "https://en.wikipedia.org/wiki/Barack_Obama#/media/File:DIG13623-230.jpg"}
 ]
} Example 2. Parameter 1: Multiple Image URLs {
 "images": [
 {
 "url": "https://en.wikipedia.org/wiki/Barack_Obama#/media/File:DIG13623-230.jpg"
 },

For additional details on how pricing works, see Algorithmia pricing.

Internet access

This algorithm has Internet access. This is necessary for algorithms that rely on external services, however it also implies that this algorithm is able to send your input data outside of the Algorithmia platform.

Calls other algorithms

This algorithm has permission to call other algorithms. This allows an algorithm to compose sophisticated functionality using other algorithms as building blocks, however it also carries the potential of incurring additional royalty and usage costs from any algorithm that it calls.

To understand more about how algorithm permissions work, see the permissions documentation.
