1. Introduction

This algorithm classifies age for each person in any given image. Currently it only supports two genders. (male & female)

Input:

(Required) Image Data API Url, Web (http/https) Url, binary image or a base64 encoded image.

Output:

Age range and bounding-box information of each person in a given image

Note: The first call to this algorithm will take a bit longer than sequential calls to due algorithm initialization. All following calls will be significantly faster.
