◆ ff_dnn_load_layer_math_unary()

int ff_dnn_load_layer_math_unary ( Layer layer,
AVIOContext model_file_context,
int  file_size,
int  operands_num 

Load the Unary Math Layer.

It assigns the unary math layer with DnnLayerMathUnaryParams 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

◆ ff_dnn_execute_layer_math_unary()

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

Execute the Unary Math Layer.

It applies the unary operator parsed while loading to the given input operands.

operandsall operands for the model
input_operand_indexesinput operand indexes for this layer
output_operand_indexoutput operand index for this layer
parametersunary math layer parameters
ctxpointer to Native model context for logging
Return values
0if the execution succeeds
AVERROR(ENOMEM)if memory allocation fails
AVERROR(EINVAL)for invalid arguments
