I am kind of confused with type() method of Mat object in OpenCV.
If I have following lines:
mat = imread("C:\someimage.jpg");
type = mat.type();
and type = 16, how do I find out what type of mat matrix is?.
I tried to find the answer in its manual and in a couple of books in vain.

For debugging purposes in case you want to look up a raw Mat::type in a debugger:
| C1 | C2 | C3 | C4 | C(5) | C(6) | C(7) | C(8) | |
|---|---|---|---|---|---|---|---|---|
| CV_8U | 0 | 8 | 16 | 24 | 32 | 40 | 48 | 56 |
| CV_8S | 1 | 9 | 17 | 25 | 33 | 41 | 49 | 57 |
| CV_16U | 2 | 10 | 18 | 26 | 34 | 42 | 50 | 58 |
| CV_16S | 3 | 11 | 19 | 27 | 35 | 43 | 51 | 59 |
| CV_32S | 4 | 12 | 20 | 28 | 36 | 44 | 52 | 60 |
| CV_32F | 5 | 13 | 21 | 29 | 37 | 45 | 53 | 61 |
| CV_64F | 6 | 14 | 22 | 30 | 38 | 46 | 54 | 62 |
So for example, if type = 30 then OpenCV data type is CV_64FC4. If type = 50 then the OpenCV data type is CV_16UC(7).
