4e513a3346 Imgcodecs: Fixed a bug with checkSignature in GdalDecoder
In cases where the signaure string contains a terminating character,
the std::string member function size returns a smaller value than the
allocated string. In these cases, if you then try to use substr,
you will get an out_of_range exception. This patch remedies the problem.

6172803012 imgcodecs: Implementation of PAM encoder/decoder
This patch implements the PAM image format as defined at:
http://netpbm.sourceforge.net/doc/pam.html

The PAM format provides a generic means for storing 2 dimensional information.
This is useful for opencv since there are cases where data gets translated into
non standardized formats, which makes it difficult to store and load this information.

9e61a28b2e Improve canny (#7227)
* Improve Canny by using _mm_movemask_epi8 to find next pixel magnitude greater than lower threshold. Added parallelized finalPass to Canny with variable gradients. Little changes in finalPass.

* Some things fixed

903789f7af use universal intrinsic for FP16
* use v_float16x4 (universal intrinsic) instead of raw SSE/NEON implementation
  * define v_load_f16/v_store_f16 since v_load can't be distinguished when short pointer passed
  * brush up implementation on old compiler (guard correctly)
  * add test for v_load_f16 and round trip conversion of v_float16x4
  * fix conversion error

517be4bfa9 Changes [error localizedDescription] for [error description] in NSLog
There's no sense to log error messages in user’s locale.
Imagine you’re trying to guess what's going on decrypting logs in hebrew, arabic, slavic. localizedDescription is for end user messages, not for logs.
