◆ configure()

void configure	(	const ITensor *	input1,
		const ITensor *	input2,
		ITensor *	output,
		const PriorBoxLayerInfo &	info
	)

Set the input and output tensors.

Parameters

[in]	input1	First source tensor. Data types supported: F32. Data layouts supported: NCHW/NHWC.
[in]	input2	Second source tensor. Data types and layouts supported: same as `input1`
[out]	output	Destination tensor. Output dimensions are [W * H * num_priors * 4, 2]. Data type supported: same as `input`
[in]	info	Prior box layer info.

◆ name()

const char* name ( ) const

inlineoverridevirtual

Name of the kernel.

Returns: Kernel name

Implements ICPPKernel.

Definition at line 37 of file NEPriorBoxLayerKernel.h.

     {
         return "NEPriorBoxLayerKernel";
     }

◆ operator=() [1/2]

NEPriorBoxLayerKernel& operator= ( const NEPriorBoxLayerKernel & )

delete

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

◆ 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]	window	Region on which to execute the kernel. (Must be a region of the window returned by window())
[in]	info	Info about executing thread and CPU.

Reimplemented from ICPPKernel.

◆ validate()

Status validate	(	const ITensorInfo *	input1,
		const ITensorInfo *	input2,
		const ITensorInfo *	output,
		const PriorBoxLayerInfo &	info
	)

static

Static function to check if given info will lead to a valid configuration of NEPriorBoxLayerKernel.

Parameters

[in]	input2	Second source tensor info. Data types and layouts supported: same as `input1`
[in]	output	Destination tensor info. Output dimensions are [W * H * num_priors * 4, 2]. Data type supported: same as `input`
[in]	info	Prior box layer info.

Returns: a status
