Road scene image from which page statistics were generated using Student Version of Matlab

The image above and following numbered statistics were generated using Matlab Student Version from The MathWorks.

For the image with the likely projections shown above, the whos command indicated a grand total of 11,638,361 elements using 81,062,863 bytes.

Also, the command st = whos indicated a 937 element structure array. Of those 937 elements:
1)   One was of class cell array.

2)   Eighteen were of class char array.

3)   Nine hundred and six were of class double array with 789,792,352 bytes.

4)   Nine were of class uint8 array.

5)   Eighteen were of class char array.


From the profile command, the functions with the largest time plots were (from largest to smallest time percentages) (including but not limited to):
1)   There is a 'main' script file for the 'menu driven' interface from which all other functions are called.

2)   The function which includes but is not limited to that which performs the 'connected components analysis' has 98 calls and 22.5% of processing time (opt).

3)   The function which performs the 'first level discrimination' has 8 calls and 7.85% opt.

4)   The function which 'extracts preliminary color information' has 1 call and 6.37% opt.

5)   The function which performs the 'statistical correlation with the detector(s)' has 6 calls and 5.87% opt.

6)   The function which performs the 'higher level discrimination' has 29 calls and 5.37% opt.

7)   The function which performs the 'gradient magnitude and angle approximation' has 1 call and 4.8% opt.

8)   The function which performs the 'RGB to HSV transform' has 1 call and 4.36% opt.

9)   The function which performs the 'preliminary histogram calculations' has 4 calls and .34% opt.

10) The function which performs the 'RGB to YIQ transform' has 1 call and 3.00% opt.

11) The function which performs the 'color supported region approximations' has 1 call and 2.89% opt.

12) The function which performs the 'higher level discrimination' has 9 calls and takes up approximately 2.07% opt.

13) The function which performs the 'GEM manipulation' has 348 calls and takes up approximately 1.53% opt.

14) The function which performs the 'GEM manipulation' has 8 calls and takes up approximately 1.51% opt.

15) The function which performs the 'histogram equalization' has 2 calls and takes up approximately 1.25% opt.

16) The function which performs the 'GEM manipulation' has 221 calls and takes up approximately 0.71% opt.

17) The function which performs the 'GEM manipulation' has 212 calls and takes up approximately 0.67% opt.

Overall, the system includes but is not limited to approximately 185 Matlab files with approximately 90,000 lines  of code.
