Tuesday (10/16/18)
Agenda:
- Creating a blank image and manipulating the pixels
- Rotate 90 degrees clockwise
- Complete and demo the following image processing filters:
- Rotate 90 degrees clockwise of a non-square image
- Mosaic
- Take an image, sample every (10th row, 10th col) pixel's color
- Draw a 10x10 square using the sampled pixel's color at ever 10th (x,y)
- You should display both the original image and its mosaic
- Pointilism
- Turn off lines via noStroke()
- Take an image, sample every (5th row, 5th col) pixel's color
- Draw an ellipse of size 4 diameter using the sampled fill color in the corresponding location
Tuesday - Friday (10/9/18 - 10/12/18)
Agenda:
- Demo Media:BubbleSort.java
- Algorithms Identification Quiz in Canvas
- Reference variables overview
- Two-Dimensional Arrays and Nested Loops
- Accessing all of the individual elements of a two-dimensional list
- Prompt the user to construct a two-dimensional list
- Prompt for the number of rows
- Prompt for the number of columns
- Prompt the user for each number in the two-dimensional list
- Write a method: void matrixPrint(int[][] m)
- Print each row on a separate line, and each element should be separated by a space
- Complete the method in repl.it
- Nested Loops, Processing & Images
- Processing coordinate system review (print mouse coordinates)
- Processing PImage object practice
- Processing: Images & Pixels Tutorial
- As a class, we'll walk through several of the examples from the tutorial above, and we'll modify each slightly
- Image Processing Exercises?
- Convert to black and white
- Rotate image 90 degrees
- Flip vertical
- Flip horizontal
- Pointilism
- Mosaic
- Edge detection?
Homework Challenge:
- Try to complete the rotate 90 degrees image challenge
