Understanding Image Processing Concepts

Lydia Choi, a technical art director at Oculus, introduces a pixelation widget for encoding black and white images using binary code. The tutorial covers setting image dimensions, encoding pixel colors, and using formatting tools to manage binary code. It concludes with instructions on saving and viewing the created images.

What is Lydia Choi's role at Oculus?

• Graphic Designer

• Technical Art Director

• Software Engineer

• Product Manager

What is the main focus of the virtual reality tool Lydia is working on?

• Simulating clay sculpting in space

• Creating virtual reality games

• Designing virtual reality headsets

• Developing virtual reality movies

What is the main purpose of the pixelation widget?

• To edit videos

• To encode black and white images using binary

• To design 3D models

• To create colorful images

How are the width and height of an image defined in the widget?

• Using RGB values

• Using decimal numbers

• Using two bytes of binary data

• Using hexadecimal values

What does a '1' represent in the binary code for pixel colors?

• Black

• Gray

• Transparent

• White

What is the purpose of adding line breaks in the binary code?

• To increase image size

• To change the color of pixels

• To reduce file size

• To keep track of rows

What does the 'raw format' button do?

• Strips out spaces and line breaks

• Saves the image

• Adds spaces and line breaks

• Changes the image color

How can you view your image using real pixels on your computer?

• By clicking 'zoom in'

• By clicking 'actual size'

• By clicking 'save PNG'

• By clicking 'edit mode'

What happens when you click 'save PNG'?

• The image is converted to grayscale

• The image is saved as a PNG file

• The image is deleted

• The image is printed

What is the benefit of using the 'readable format' button?

• It makes the binary code easier to read and edit

• It compresses the image

• It changes the image resolution

• It adds color to the image
