◆ configure()

void configure ( const ITensor input1,
const ITensor input2,

Parameters
[in]input1First source tensor. Data types supported: F32. Data layouts supported: NCHW/NHWC.
[in]input2Second source tensor. Data types and layouts supported: same as input1
[out]outputDestination tensor. Output dimensions are [W * H * num_priors * 4, 2]. Data type supported: same as input
[in]infoPrior box layer info.

◆ name()

◆ operator=() [1/2]

NEPriorBoxLayerKernel& operator= ( const NEPriorBoxLayerKernel )
delete

Prevent instances of this class from being copied (As this class contains pointers)

Referenced by NEPriorBoxLayerKernel::name().

◆ operator=() [2/2]

NEPriorBoxLayerKernel& operator= ( NEPriorBoxLayerKernel &&  )
default

Allow instances of this class to be moved.

◆ run()

void run ( const Window window,
const ThreadInfo info 
)
overridevirtual

Execute the kernel on the passed window.

Warning
If is_parallelisable() returns false then the passed window must be equal to window()
Note
The window has to be a region within the window returned by the window() method
The width of the window has to be a multiple of num_elems_processed_per_iteration().
Parameters
[in]windowRegion on which to execute the kernel. (Must be a region of the window returned by window())
[in]infoInfo about executing thread and CPU.

Reimplemented from ICPPKernel.
