5. Color changer
Using a color image, write a program to automatically map all the colors
to dierent values. For example, the program could make all the colors like
pastels. Or, the program could change all colors to gray except for one, e.g.,
highlighting green.
6. Red-eye removal
Often pictures show people with red eyes, due to the ash. An interesting
project would be to automatically detect and remove red-eye. To make the
problem easier, assume that the eye areas are given by the user.
7. Tank nder
Devise a way to nd a specic object in an image, such as a military tank.
Your program should return a ag indicating whether or not a tank is present,
and if so, the position of the tank in the image. This can be a very complex
project, so you may want to simplify things by assuming that the tank is a
black outline on a white background. Your program should be able to nd
the tank regardless of its place in the image, called translation. Variations
on this idea (each of which would be a project on its own) include: detecting
the object regardless of rotation, detecting the object regardless of obstruction
(such as being partially obscured by another object), and detecting the object
regardless of scale (smaller or larger).
8. Cat identication system
Many cat owners can recognize their cat from its meow. Develop a system
that attempts to correctly identify a particular cat from many dierent cat
recordings.
9. Dog translator
Dog owners often know what their dog wants by the way it barks and whines.
Develop a system to discern between the noises your dog makes when it sees
another dog, it is hungry, someone knocks at the door, it wants to go out, etc.
10. Object separation
Make a program to separate an image into a foreground and background image.
For example, take a picture of a person's face and store it as a grayscale image.
Your program should be able to create a new image from this with only the
person's face on a white background.
11. Music nder
Using MATLAB and a microphone, record a fraction of a second of sound,
