Bluetooth PTT talkback system

The invention discloses a bluetooth PTT talkback system which comprises a bluetooth module device provided with a bluetooth headset mic interface and a loudspeaker, wherein a PTT key is arranged on the bluetooth module device and electrically connected with an I/ O port with built-in bluetooth module of the bluetooth module device and the bluetooth module is connected with an audio input module and an audio output module through a pulse code modulation (PCM) interface. The audio input module is connected with the headset mic interface through a bluetooth module audio input circuit, and the audio output module is connected with the loudspeaker through a bluetooth module audio output circuit. By means of the bluetooth PTT talkback system, PTT talkback and professional cluster talkback functions of any mobile terminal with bluetooth can be achieved quickly, and requirements on functions of professional applications such as the PTT key and volume during application of a public network talkback mobile terminal in cluster talkback service are met. Customization requirements on adaption to characteristics of an interphone of mobile phones utilizing a public mobile data network currently to provide a talkback function can be removed, and cost on research of public network intercommunication phones is greatly reduced.

Multi-pose face recognition method based on MB-LBP features and face energy diagram

The invention provides a multi-pose face recognition method based on MB-LBP features and a face energy diagram. According to the method, a multi-pose face image training library is established, and after size normalization processing is carried out on face images, a face mean value energy diagram and a variance energy diagram of the training library are established; MB-LBP feature extracting is carried out on the obtained face mean value energy diagram and the variance energy diagram, and the MB-LBP features are stored as matching library information; when face detection is carried out, the face images are detected and face regions are extracted, and size normalization processing is carried out on the images of the face regions to obtain standard face images; MB-LBP feature extracting is carried out on the standard face images; finally, classification and recognition of multi-pose faces are completed by adopting a nearest neighbor classifier. According to the multi-pose face recognition method based on the MB-LBP features and the face energy diagram, the intrinsic macroscopic features of the multi-pose faces can be maintained well, the microstructure and the macrostructure of a face image mode are reserved, influences brought by single pixel noise can be removed, needed storage space is small, and the method has an excellent recognition rate and recognition speed.
