max pool Layer with mask #4891

python usage:

tmp = paddle.layer.img_pool(
                         input=tmp,
                         pool_size=7,

There is no need to add this interface. Only need to add a maskData parameter to the original interface.

Do not change this file.
We can add a PoolMaxWithMaskLayer, and create this layer in the PoolLayer::create when pool == "max-pool-with-mask" .

hedaoyuan

Do not modify the implementation of the original Layer. The current Operator refactoring is based on the Layer, modify the original Layer implementation may be confused on the reconstruction. You can add a PoolMaxWithMaskLayer to avoid modifying the original layer.

Is the if (maskMatP == NULL) can be inside the for loop? And use maskData == NULL instead of maskMatP == NULL.

Is it can be modified into caffeMode = true? The other Layer (Pooling, Conv) default is true.

The caffeMode in poolProjection.cpp is false, i referred there. https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/gserver/layers/PoolProjection.cpp#L51

If you change the value of caffeMode in the Layer, this also needs to be modified.
