Using " processing"

Inside draw( ) function, design following mechanisms along with

for loop to read pixels;

a)

image( ) function to draw

b)

Use red( ), green(), and blue( ) functions to show only red,

green, or blue channels.

c)

Mapping between the pixel position, bar height, bar color ,

font color and pixel position:

a)

To show an interactive RGB value on a specific pixel

based on the position of mouse cursor (mouseX &

mouseY), create a bar graph (e.g., use rect( ) to create

3 bars) and make the heights of bars reflecting the

intensities of red, green, and blue color on each pixel.

Feel free to choose another shape (through changing

the size of ellipse) showing intensity of color value.

b)

Useful Processing commands;

text( ), textFont( )

Color, image( ), fill( )

updatePixels();

loadPixels();

d)

Apply key interactions to different pre-built filter effects.

e)

Based on simple math operators (+, -, *, %), design your

own image processing color filters which can be operated

through key board interaction (e.g., pressing r to increase

redness etc.)
