Ari Koivula 947bae24f9 Update Doxygen documentation 
Add module information to all header files.

Update all header file documentations to briefly say what they are, and
to use the javadoc format so the brief actually gets included into the
doxygen documentation.

Remove \file from implementation files, in order to not repeat the info
from the header files.

Add files under strategies and tools to Doxygen and update the Doxygen
settings to be just plain better.

Make README be the main page of Doxygen documentation.

Arttu Ylä-Outinen 056fa09ba5 Add arbitrary-sized SATD functions. 
Adds strategy satd_any_size for generic and AVX2. The satd_any_size
functions are implemented with macro SATD_ANY_SIZE defined in
strategies-picture.h.
 2015-12-15 11:21:45 +02:00
Arttu Ylä-Outinen 728a6abecc Extract macro SATD_NxN. 
Combines definitions of macros SATD_NXN and SATD_NXN_AVX2 to macro
SATD_NxN and moves it to strategies-picture.h.

Arttu Ylä-Outinen 4402e251ae Fix kvz_get_extended_block functions. 
The buffers allocated in functions kvz_get_extended_block_avx2 and
kvz_get_extended_block_generic were too small when the width of the
block was less than its height. Fixed to allocate correctly sized
buffers.

Arttu Ylä-Outinen 940ada4c0d Mark AVX2 intra filter functions as static. 
Marks functions filter_4x4_avx2, filter_16x16_avx2 and filter_NxN_avx2
static as they are not used outside strategies/avx2/intra-avx2.

Ari Koivula 0c3c93d456 Optimize intra SAD intrinsics. 
- Added 64x64 version for completeness.
- With the exception of 16x16, these were all slightly slower than the ASM
  versions, as measured by "kvazaar_test -s speed -t intra_sad", but now they
  are on par or slightly faster.
- None of these actually use any AVX2 intrinsics, and probably never will,
  unless someone adds an interface for doing more than one block at a time,
  in which case the non-destructive versions might come in handy.
