Std 7: ICT 09: Computer Vision - Questions and Answers
♦ Artificial intelligence (AI)
The term Artificial Intelligence was coined in 1956 by an American computer scientist called John Mac- Carthy.
♦ Block Programming
Block programming is a method of creating a computer program using pre-prepared code. In this kind of programming, code is given as separate blocks which can be dragged and placed as required to make a program.
♦ PictoBlox
There is a piece of software based on Scratch called PictoBlox -an improved software program which enables us to make computer programs based on AI.
♦ Some Facilities in PictoBlox
• It has block programming, as in scratch.
• It has the facility to write programs with Python.
• It has extensions to do activities of Al and Robotics.
♦ Code Block related to face detection in the Picto- Blox.
• We have to keep the computer camera on.
• The picture captured by the camera is to be analysed.
• Once the face is detected in the picture, based on the previously analysed faces, its expression must be recognised.
• There must be a reaction in accordance with the recognised expression.
•The activity has to be repeated.
♦ Costumes for Expressions
Using PictoBlox, we can give different costumes to a sprite for detectable expressions.
♦ Adding new costumes in PictoBlox
• Delete the existing sprite and add a new sprite (The first costume) through upload sprite.
• Select the tab, costumes
• Select 'Choose a Costume→ Upload Costume' at the left bottom.
• Add the other costumes for the sprite selected from the computer.
♦ Preparing the program
The program that displays smileys in keeping with the expressions Caught in the Camera.
♦ Let's Save
To save your work in PictoBlox, click on the save option in file menu, and type in the window the file name and click on save.
♦ Assessment
1. You prepared the computer vision program that reacts after detecting facial expressions. List some situations where computer vision can be used.
