AIM:

Using image data, predict the gender and age range of an individual in Python. Test the data science model using your own image.

THEORY:

Age and gender, two of the key facial attributes, play a very foundational role in social interactions, making age and gender estimation from a single face image an important task in intelligent applications, such as access control, human-computer interaction, law enforcement, marketing intelligence and visual surveillance, etc.

Here, we have performed Gender Detection i.e. predicting ‘Male’ or ‘Female’ using deep learning libraries and OpenCV to mention the gender predicted.

Age detection is the process of automatically discerning the age of a person solely from a photo of their face.

There are a number of age detector algorithms, but the most popular ones are deep learning-based age detectors

Typically, you’ll see age detection implemented as a two-stage process:

1. Stage #1: Detect faces from input image

2. Stage #2: Extract the face Region of Interest (ROI), and apply the age detector algorithm to predict the age of the person

For Stage #1, any face detector capable of producing bounding boxes for faces in an image can be used

The face detector produces the bounding box coordinates of the face in the image.

For Stage #2 — identifying the age of the person.

Given the bounding box (x, y)-coordinates of the face, we first extract the face ROI, ignoring the rest of the image/frame. Doing so allows the age detector to focus solely on the person’s face and not any other irrelevant “noise” in the image.

The face ROI is then passed through the model, yielding the actual age prediction.
