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

Load the 2D Convolution Layer. More...

int ff_dnn_execute_layer_conv2d (DnnOperand *operands, const int32_t *input_operand_indexes, int32_t output_operand_index, const void *parameters, NativeContext *ctx)

Execute the 2D Convolution Layer. More...

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

int ff_dnn_execute_layer_conv2d ( DnnOperand * operands,

const int32_t * input_operand_indexes,

int32_t output_operand_index,

const void * parameters,

NativeContext * ctx

)

Execute the 2D Convolution Layer.

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 convolution parameters

ctx pointer to Native model context for logging

Return values: 0 if the execution succeeds

DNN_ERROR if the execution fails
