Function Documentation

ff_dnn_load_layer_depth2space()

int ff_dnn_load_layer_depth2space	(	Layer *	layer,
		AVIOContext *	model_file_context,
		int	file_size,
		int	operands_num
	)

Load the Depth to Space Layer.

It assigns the depth to space layer with DepthToSpaceParams after parsing from the model file context.

Parameters

layer	pointer to the DNN layer instance
model_file_context	pointer to model file context
file_size	model file size to check if data is read correctly from the model file
operands_num	operand count of the whole model to check if data is read correctly from the model file

Returns

number of bytes read from the model file

Return values

0	if an error occurs or out of memory

ff_dnn_execute_layer_depth2space()

int ff_dnn_execute_layer_depth2space	(	DnnOperand *	operands,
		const int32_t *	input_operand_indexes,
		int32_t	output_operand_index,
		const void *	parameters,
		NativeContext *	ctx
	)

Execute the Depth to Space Layer.

It rearranges the input data from depth into spatial form by applying Depth to Space transformation.

Parameters

operands	all operands for the model
input_operand_indexes	input operand indexes for this layer
output_operand_index	output operand index for this layer
parameters	depth to space layer parameters
ctx	pointer to Native model context for logging

Return values

0	if the execution succeeds
AVERROR(ENOMEM)	if memory allocation fails
AVERROR(EINVAL)	for invalid arguments
