Mutable methods for crate::dnn::TextRecognitionModel

Required Methods§

source

fn as_raw_mut_TextRecognitionModel(&mut self) -> *mut c_void

Provided Methods§

source

fn set_decode_type(&mut self, decode_type: &str) -> Result<TextRecognitionModel>

Set the decoding method of translating the network output into string

§Parameters
  • decodeType: The decoding method of translating the network output into string, currently supported type:
    • "CTC-greedy" greedy decoding for the output of CTC-based methods
    • "CTC-prefix-beam-search" Prefix beam search decoding for the output of CTC-based methods

Set the decoding method options for "CTC-prefix-beam-search" decode usage

§Parameters
  • beamSize: Beam size for search
  • vocPruneSize: Parameter to optimize big vocabulary search, only take top @p vocPruneSize tokens in each search step, @p vocPruneSize <= 0 stands for disable this prune.
§C++ default parameters
  • voc_prune_size: 0
source

fn set_decode_opts_ctc_prefix_beam_search_def( &mut self, beam_size: i32 ) -> Result<TextRecognitionModel>

Set the decoding method options for "CTC-prefix-beam-search" decode usage

§Parameters
  • beamSize: Beam size for search
  • vocPruneSize: Parameter to optimize big vocabulary search, only take top @p vocPruneSize tokens in each search step, @p vocPruneSize <= 0 stands for disable this prune.
§Note

This alternative version of TextRecognitionModelTrait::set_decode_opts_ctc_prefix_beam_search function uses the following default values for its arguments:

  • voc_prune_size: 0
source

fn set_vocabulary( &mut self, vocabulary: &Vector<String> ) -> Result<TextRecognitionModel>

Set the vocabulary for recognition.

§Parameters
  • vocabulary: the associated vocabulary of the network.

Object Safety§

This trait is not object safe.
