PyramidDownGen is used to construct a pyramid node in the expression tree with general Filter2D and general DownSmplOP functors.

It automatically generates the tuple of output based on the depth. template parameters:

Template Parameters

Fltr2DOP	general Filter2D function
DownSmplOP	downsampling function for pyramid
Cols	determines the column size of the input pyramid
RHS	is the input passed for pyramid
Fltr2D	is the filter2d node
Rows	determines the row size of the input pyramid
LfType	determines the type of the leafNode {Buffer2D, Buffer1D, Host, Image}
LVL	the level of the node in the expression tree
Dp	represents the depth of down sampling

sub_expression_evaluation

This function is used to break the expression tree whenever necessary. The decision for breaking the tree will be determined based on the static parameter called SubExpressionEvaluationNeeded. When this is set to true, the sub_expression_evaluation is called recursively from the root of the tree. Each node based on their parent decision will decide to launch a kernel for itself. Also, they decide for each of their children whether or not to launch a kernel separately. template parameters:

Template Parameters

ForcedToExec	: a boolean value representing the decision made by the parent of this node for launching a kernel.
LC	is the column size of local memory required by Filter2D and DownSmplOP
LR	is the row size of local memory required by Filter2D and DownSmplOP
LCT	is the column size of workgroup
LRT	is the row size of workgroup
DeviceT	type representing the device function parameters:

Parameters

dev	: the selected device for executing the expression

Returns: LeafNode
