* enabled convolution & activation fusion
* a few more optimizations:
+ optimized the common case when the indices of max pooling layer are not used. in this case we use the more efficient branch that computes just maximums over the aperture.
+ optimized the convolution + activation fusion when the activation is relu, which is another common case
+ convolution can now be fused with batch norm. It's the zero-cost fusion. If the batch norm is followed by relu, all three (conv + batchnorm + relu) are fused together. this modification seriously improved ENet performance

* 1 : implement cross-correlation rather than using matchTemplate since the
results of matchTemplate are weird
2 : remove gamma param, although the paper said PHash apply gamma
correction on the image, but the codes do not do that(I think it is a bug
of PHash)

* 1 : implement function "getDefaultName"
2 : adjust style
* Update README.md
1 : Fix wrong branch
2 : Add another solution to download img_hash
* img_hash: refactored interfaces to use pImpl
* remove trailing white space
* img_hash: use type-safe pImpl
* change name, easier to find the source file
* 1 : narrow scope of ImgHashImpl
2 : use static cast to replace dynamic cast because class hierarchy of
img_hash is very straightforward
* should not declare ImgHashImpl api in the header file of ImgHashBase, this increase chance of breaking ABI
* should not declare ImgHashImpl api in the header file of ImgHashBase, this increase chance of breaking ABI
* fix warning, because unelaborated friend declaration is a C++11 extension
* first commit
* fix bug, except of windows, other platforms cannot access private member.
pimpl only accessable by the class itself, therefore I think declare
everything as public is quite safe
* first commit comparison and computation charts
* update chart link
* some further optimizations and cleanups in dnn:
+ got rid of dnn::gemm; it's not perf critical anymore (perhaps)
+ embedded col2im functionality into convolution_layer.cpp, since it's not used anywhere else
+ parallel max pooling. even better performance can be achieved if we knew that max indices are not needed (and they are not needed in most networks)
+ somewhat optimized deconvolution layer: optimized bias addition (merged it with col2im), optimized col2im slightly.
+ hopefully fixed incorrect memory access in fully-connected layer; restored aligned memory reads (they should work fine now)
* hopefully fixed regressions in ENet performance
* fixed some typos in deconvolution; added SIMD optimization for the max pooling layer
* fixed warnings in SIMD-less build configuration
* rewritten the following layers to be [much] more efficient: convolution, fully connected, activations (relu, tanh, ...), LRN. Use optional AVX optimization for the first two.
* eliminated trailing whitespaces
The while loop in member function buildPyramid in deepflow.cpp terminated as a result of the break statement and never as a result of the termination criteria because the "i" variable in the while loop was never incremented.
Changed the while loop into a for loop
Changed the while loop into a for loop in the member function buildPyramid in deepFlow.cpp
