Dlib deserialize Gesicht Form Modell mit iStream

Question

Ich bin total noob wie es zu dlib kommt. Ich weiß, wie man Gesichtsformmodell direkt von der Akte lädt und es funktioniert.

dlib::shape_predictor face_shape_predictor_; 
dlib::deserialize("shape_predictor_68_face_landmarks.dat") >> face_shape_predictor_; 

Aber wie aus istream zu deserialisieren?

Ich habe den folgenden Code:

dlib::shape_predictor face_shape_predictor_; 
std::stringstream face_data_stream; 

loadDataToStream(face_data_stream); 
dlib::deserialize(face_shape_predictor_, face_data_stream); 

Und ich weiß nicht, wie es die Arbeit.

Answer 1

Eigentlich Hinzufügen von den folgenden Code:

using namespace dlib; 

die Kompilierung Problem gelöst.

Answer 2

Das erste Suchergebnis in Google nach "DLIB deserailize" führt zu diesem Text;)

There are two global functions in the dlib namespace that provide serialization and 
deserialization support. Their signatures and specifications are as follows: 

    void serialize (
     const serializable_type& item, 
     std::ostream& out 
    ); 
    /!* 
     ensures 
      - writes the state of item to the output stream out 
      - if (serializable_type implements the enumerable interface) then 
       - item.at_start() == true 
     throws      
      - serialization_error 
       This exception is thrown if there is some problem which prevents 
       us from successfully writing item to the output stream. 
      - any other exception 
    *!/ 

    void deserialize (
     serializable_type& item, 
     std::istream& in 
    ); 
    /!* 
     ensures 
      - #item == a deserialized copy of the serializable_type that was 
       in the input stream in. 
      - Reads all the bytes associated with the serialized serializable_type 
       contained inside the input stream and no more. This means you 
       can serialize multiple objects to an output stream and then read 
       them all back in, one after another, using deserialize(). 
      - if (serializable_type implements the enumerable interface) then 
       - item.at_start() == true 
     throws      
      - serialization_error 
       This exception is thrown if there is some problem which prevents 
       us from successfully deserializing item from the input stream. 
       If this exception is thrown then item will have an initial value 
       for its type. 
      - any other exception 
    *!/ 

For convenience, you can also serialize to a file using this syntax: 
    serialize("your_file.dat") << some_object << another_object; 

That overwrites the contents of your_file.dat with the serialized data from some_object 
and another_object. Then to recall the objects from the file you can do: 
    deserialize("your_file.dat") >> some_object >> another_object;
