width()

Function Definition: width(face = 1)

Parameters

Name	Type	Description	Expected Values	Default Value
face	int	Face number for which the information is required.	1-100	1

Description

This function returns the width of the face detected. You can specify the face for which the value is needed. The position is mapped with the stage coordinates.

Example

Face Detection – Stage (Python)

The example demonstrates the application of face detection with a stage feed.

The example demonstrates the application of face detection with a stage feed. Following are the key steps happening:

Initializing the program with parameters for the sprite and face detection library.
Running face detection
Running the loop to show every face and its expression

Code

sprite = Sprite('Square Box')
import time
fd = FaceDetection()

# Disable Bounding Box on the stage
fd.disablebox()

# Set Theshold of the stage
fd.setthreshold(0.4)

fd.analysestage()

print(fd.count())

for i in range(fd.count()):
  sprite.setx(fd.x(i + 1))
  sprite.sety(fd.y(i + 1))
  sprite.setsize(fd.width(i + 1))
  sprite.say("Face " + str(i + 1) + ": " + fd.expression(i + 1))
  time.sleep(1)

Output

Face Detection – Camera (Python)

The example demonstrates how to use face detection with a camera feed.

The example demonstrates how to use face detection with a camera feed. Following are the key steps happening:

Initializing the program with parameters for the sprite, and face detection library.
Running face detection.
Running the loop to show every face and expression.

Code

sprite = Sprite('Square Box')
import time
fd = FaceDetection()

fd.video("on", 0)

# Enable Bounding Box on the stage
fd.enablebox()

# Set Theshold of the stage
fd.setthreshold(0.5)

while True:
  fd.analysestage()

  for i in range(fd.count()):
    sprite.setx(fd.x(i + 1))
    sprite.sety(fd.y(i + 1))
    sprite.setsize(fd.width(i + 1))
    sprite.say(fd.expression(i + 1))
