analysestage()

Function Definition: analysestage()

Parameters

Description

This function is used to analyze the image received as input from the stage, for objects.

Alert: This block processes the image input and updates the values in the other functions hence it needs to be put inside loops while making projects.

Example

Person Detector – Python

The example demonstrates how to detect persons on the stage with different confidence thresholds.

Code

sprite = Sprite('Tobi')
obj = ObjectDetection()

obj.enablebox()
sprite.gotoxy(-180, -110)
sprite.setsize(100)

obj.setthreshold(0.3)
obj.analysestage()
sprite.say(str(obj.detectedcount("person")) + " Person Detected at 0.3 Threshold", 2)

obj.setthreshold(0.5)
obj.analysestage()
sprite.say(str(obj.detectedcount("person")) + " Person Detected at 0.5 Threshold", 2)

obj.setthreshold(0.9)
obj.analysestage()
sprite.say(str(obj.detectedcount("person")) + " Person Detected at 0.9 Threshold", 2)

Output

Object Detection on Stage – Python

The example demonstrates how to run an object detection on the stage and show all the objects with confidence.

Code

sprite = Sprite('Square Box')
obj = ObjectDetection()

obj.disablebox()
obj.setthreshold(0.5)
obj.analysestage()

sprite.gotoxy(0, 0)
sprite.setsize(100)
sprite.say(str(obj.count()) + " Object Detected", 2)

for object in range(1, obj.count() + 1):
  sprite.setx(obj.x(object))
  sprite.sety(obj.y(object))
  sprite.setsize(obj.width(object))
  sprite.say(obj.classname(object) + " with " + str(obj.confidence(object)), 2)

Output

Detection at 0.3
Detection at 0.5
Detection at 0.8
