ff_dnn_load_layer_conv2d()

int ff_dnn_load_layer_conv2d	(	Layer *	layer,
		AVIOContext *	model_file_context,
		int	file_size,
		int	operands_num
	)

Load the 2D Convolution Layer.

It assigns the 2D convolution layer with ConvolutionalParams 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 out of memory or an error occurs

parameters	convolution parameters
ctx	pointer to Native model context for logging

Return values

0	if the execution succeeds
DNN_ERROR	if the execution fails
