2. Recap
Track the eyes
Move cursor on the screen using the eyes

3. Implementation Face detection implementation Original image
Grayscale image

4. Move from RGB colour space to HSV colour space
For grayscale image H = 0, S = 0, 0 < = v <= 100
H = 0, S = 0, V = 100 represents a white pixel.

5. Eliminate white background by setting a threshold of V < 90

6. struct Pixel {
int red;
int green;
int blue;
int mark; }
If a pixel V value is less than 90 we set mark equal 1

7. Face Rectangle

8. Eye Rectangle

9. Locate pupil in eye rectangle by setting a threshold of

10. Biggest Blob Detection

11. Testing
Tested on people with black pupil

12. Shortcomings
Lack Accuracy
Lack of Speed
