One of my first image processing based project done in 2007. It finds cars on a Google Maps
|
|
|
|
|
view, based on their color.

When I started this project, I had no experience in image processing, so I tried
|
|
|
|
|
what came to my mind. Looking backward, the sources are a real mess but I
|
|
|
|
|
acquired my first image processing skills with it.

Here are the basic steps of the program:
|
|
|
|
|
|
|
|
|
|
1. Delete the unnecessary colors from the image
|
|
|
|
|
2. Classify the image in 10 colors with the K-means algorithm
|
|
|
|
|
3. Delete huge objects that can't obviously be cars
|
|
|
|
|
4. Fill tiny holes
|
|
|
|
|
5. Classify again
|
|
|
|
|
6. Remove odd shapes
|
|
|
|
|
7. Fill tiny holes again
|
|
|
|
|
8. Restore original colors
|
|
|
|
|
9. Delete pixels with low saturation
|
|
|
|
|
10. Classify again
|
|
|
|
|
11. Remove little objects
|
|
|
|
|
12. Remove odd shapes
|
|
|
|
|
13. Later, I decided to bind it with a Cocoa GUI.
