 Code.or Unit 2: Lesson 3: Encoding B&W Images

  Task 3 - Create your own

Wrap-up (10 mins)

The image file protocol we used contains “metadata”: the width and height. Metadata is “data about the data” that might be required to encode or decode the bits.

For example, you couldn’t render the B&W image properly without somehow including the dimensions.

Prompts:

-What other examples of metadata have we seen in the course so far?
-What other types of data might we want to send that would require metadata?
Assessment

Extended Learning

Check out the "Color by Numbers" from CS Unplugged (csunplugged.org) which uses a different clever encoding scheme for B&W images.

-Do the Extension: Magnify an Image (optional) - Activity Guide activity (double the size of an image on the Pixelation Tool).
Have students research raster graphics in anticipation of the subsequent lesson.

Attempting to communicate with possible intelligent life beyond our solar system has been a dream for humans and the goal of scientists for many years. Questions about messages to send, as well as how to send messages deep into space to unknown recipients have been debated. In 1974, scientists sent the Arecibo message to the star cluster M13 some 25,000 light years away. Read about the message they sent using 1,679 binary digits (https://en.m.wikipedia.org/wiki/Arecibo_message).

-How would you change the content of the message? What would you delete and add? Why would your change be significant in a communication to other intelligent beings?
-Sketch the segment of the design you would alter. Remember, you must retain the original number of bits.
-List the details in this article that you understand more deeply because of what you have learned in this class up to this point.

2.4 Encoding Color Images

Objectives

Students will be able to:

Use the Pixelation Tool to encode small color images with varying bits-per-pixel settings.
Explain the color encoding scheme for digital images.
Use the Pixelation Tool to encode an image of the student’s design.
Explain the benefits of using hexadecimal numbers for representing long streams of bits.

Vocabulary

Hexadecimal - A base-16 number system that uses sixteen distinct symbols 0-9 and A-F to represent numbers from 0 to 15.
Pixel - short for "picture element", the fundamental unit of a digital image, typically a tiny square or dot that contains a single point of color of a larger image.
RGB - the RGB color model uses varying intensities of (R)ed, (G)reen, and (B)lue light are added together in to reproduce a broad array of colors.

Agenda

Getting Started (5 mins)
Prompt: How might you encode colors?
In the previous lesson we came up with a simple encoding scheme for B&W images. What if we wanted to have color?
Devise an encoding scheme for color in an image file. How would you represent color for each pixel?
How many different colors could you represent? Do you have a particular order to the colors?
Pair and share ideas
Discuss some of the difficulties of representing color
Compare and contrast the different schemes students come up with.
Activity (40 mins)
The way color is represented in a computer is different from the ways we represented text or
numbers. With text, we just made a list of characters and assigned a number to each one. As you are
about to see, with color, we actually use binary to encode the physical phenomenon of LIGHT. You saw
this a little bit in the previous lesson, but today we will see how to make colors by mixing different
amounts of colored light.
Video: A Little Bit about Pixels
Important ideas from this video include:
Image sharing services are a universal and powerful way of communicating all over the world.
Digital images are just data (lots of data) composed of layers of abstraction: pixels, RGB, binary.
The RGB color scheme is composed of red, green, and blue components that have a range of
intensities from 0 to 255.
Screen resolution is the number of pixels and how they are arranged vertically and horizontally, and
density is the number of pixels per a given area.
Digital photo filters are not magic! Math is applied to RGB values to create new ones.
Color Pixelation Widget
Distribute the Activity Guide: Encoding Color Images - Activity Guide
Direct students to work in Code Studio.
There are 3 tutorial videos that appear in Code Studio that guide students through the
This activity guides students through a few levels to get used to representing pixel data with
more than one bit per pixel. It works up to full 24-bit RGB color and will present hexadecimal
as a convenient way to represent binary information for humans to read.
Activity 2 (30-40 mins)
MISCONCEPTION ALERT
It is important to note that hexadecimal numbers are used to aid humans in reading longer
strings of bits, but they in no way change the underlying data being represented. Instead, they
allow us to read 4 bits at a time rather than 1, and so allow us to more easily parse binary
information. Hexadecimal representation is NOT a form of compression, since the underlying
binary representation is not changing at all. Rather it is a more convenient way of representing
that binary information when humans need to read and interact with it.
You may wish to separately address this topic as a class. Students can practice with the
if you deem more practice necessary.

Step 1: 3-bit color

Step 2: 6-bit color

Step 3: 12-bit color and Hex
Personal Favicon Project
Directions:
Create a personal 16x16 favicon and encode it using the Pixelation Widget on the final level of
this lesson in Code Studio.
The image you make should represent your personality in some distinctive way. You will be
using this favicon in future lessons and web sites that you make, so be creative and
thoughtful.
After you have finished your favicon, share it with others in the class by sending them the bits
with the Internet Simulator Widget!
Requirements
The icon must be 16x16 pixels.
You must use the Pixelation Widget to encode the bits of color information.
The image must be encoded with at least 12 bits per pixel.
Things to think about
A simple design with a few basic colors is probably the best solution. How could you use more colors?
Plan ahead: Sketch your design before starting to encode the bits. You might want to use a tool to help you draw small images. Suggestions:
Favicon Maker: http://www.favicon.cc/
Wrap-up
Submit Favicon
You should ask students to submit a .png version of their favicon, blown up to a larger size.
And ask them to send you the bits that made up the image.

Code.org Reflections
Extended Learning
(HW - Due Saturday by noon - see calendar)
If you had to send your favicon using the sending bits widget, it would probably take a long time. Could
you compress your image? How? Describe in broad strokes the kinds of things you could do.
Read Blown to Bits (www.bitsbook.com), Chapter 3, Ghosts in the Machine, pp. 95-99 (Hiding
Information in Images), then answer the following questions:
Besides hiding information sent to others, what other uses can steganography have for
everyday users? For example, what uses would steganography have for an American

businessman in China?
