1
00:00:01,260 --> 00:00:04,563
Order contrast is a novel enhancement technique developed

2
00:00:04,563 --> 00:00:07,980
by forensic comparison software, akin to automated contrast

3
00:00:07,980 --> 00:00:10,999
enhancement, but much more powerful. It improves the

4
00:00:10,999 --> 00:00:14,416
clarity and visibility of detail on all fingerprint images,

5
00:00:14,416 --> 00:00:17,491
but in particular in the case of under or overexposed

6
00:00:17,491 --> 00:00:20,794
impressions. It uses advanced algorithms to automatically

7
00:00:20,794 --> 00:00:24,155
adjust image contrast, revealing subtle details that might

8
00:00:24,155 --> 00:00:27,515
otherwise remain hidden. To demonstrate, I've inserted the

9
00:00:27,515 --> 00:00:30,932
same image into both panels of FCS. Here I've activated the

10
00:00:30,932 --> 00:00:31,800
auto contrast.

11
00:00:31,800 --> 00:00:34,170
Little to the left screen.

12
00:00:34,170 --> 00:00:36,708
You can see that the entire image has been made much

13
00:00:36,708 --> 00:00:40,960
clearer and much more detail has been revealed.

14
00:00:46,720 --> 00:00:50,114
But what about underexposed images such as this one? Images

15
00:00:50,114 --> 00:00:53,508
may have underexposed sections that require enhancements at

16
00:00:53,508 --> 00:00:56,788
a different rate than other parts of the same image. Auto

17
00:00:56,788 --> 00:00:59,504
contrast are just to take this into account and

18
00:00:59,504 --> 00:01:02,784
automatically sets the contrast to the localized areas of

19
00:01:02,784 --> 00:01:05,690
that same image.

20
00:01:10,880 --> 00:01:13,785
Here is another underexposed image where auto contrast

21
00:01:13,785 --> 00:01:16,954
improves the visibility of the detailed and this impression

22
00:01:16,954 --> 00:01:19,860
automatically zooming in you can see the finer details

23
00:01:19,860 --> 00:01:24,290
becoming much clearer for comparison purposes.

24
00:01:27,200 --> 00:01:30,035
Here is another underexposed image becoming much clearer

25
00:01:30,035 --> 00:01:33,030
using auto contrast.

26
00:01:34,520 --> 00:01:37,151
In this case, further improvements are made using the Gamma

27
00:01:37,151 --> 00:01:40,380
tool under the levels layer.

28
00:01:40,710 --> 00:01:43,417
The same gamma tool applied to the right panel also

29
00:01:43,417 --> 00:01:46,541
improves clarity, but not nearly to the same extent as with

30
00:01:46,541 --> 00:01:49,270
auto contrast.

31
00:01:51,560 --> 00:01:57,150
Overexposed images can also be improved using auto contrast.

32
00:02:03,630 --> 00:02:06,397
The difference order contrast can make can sometimes be

33
00:02:06,397 --> 00:02:09,830
quite dramatic, as seen here.

34
00:02:11,420 --> 00:02:14,686
Impressions developed using cyanoacrylate. Another example

35
00:02:14,686 --> 00:02:17,787
of how auto contrast improves clarity and visibility of

36
00:02:17,787 --> 00:02:19,800
details in the image.

37
00:02:19,800 --> 00:02:22,751
Further applying grayscale and inverting the image along

38
00:02:22,751 --> 00:02:25,236
with gamma adjustments leads to an even further

39
00:02:25,236 --> 00:02:27,910
improvements.

40
00:02:32,810 --> 00:02:35,912
Here, son acrylate impressions developed on a plastic bag

41
00:02:35,912 --> 00:02:40,640
are also dramatically improved using auto contrast.
