◆ 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.

layerpointer to the DNN layer instance
model_file_contextpointer to model file context
file_sizemodel file size to check if data is read correctly from the model file
operands_numoperand count of the whole model to check if data is read correctly from the model file
number of bytes read from the model file
Return values
0if out of memory or an error occurs
