Photographing method and device of mobile terminal

The invention belongs to the technical field of mobile terminals, and provides a photographing method and device of a mobile terminal. The photographing method comprises the steps that picture recognition is conducted on a preview picture of a camera of the mobile terminal, and the position of a face in the preview picture is determined; the rotation angle is calculated based on the position relation between the position of the face and the golden section ratio of the preview picture; the camera of the mobile terminal is controlled to rotate by the rotation angle so as to accomplish photographing. By the adoption of the photographing method of the mobile terminal, when a user conducts self photographing operation through the mobile terminal, the camera of the mobile terminal can rotate according to the position relation between the position of the face and the golden section ratio in the framing process, and therefore the good picture composition effect is automatically generated, the phenomenon that due to the fact that photographing operation is repeatedly conducted when taken pictures are poor in composition, meaningless energy consumption of the mobile terminal is caused is avoided, and energy consumption is reduced.

Method, device and system for testing application program

The invention discloses a method, a device and a system for testing an application program. The method comprises steps as follows: an interface where testing operation of the tested application program is executed, operation execution coordinates during execution of testing operation on the interface and a recorded picture corresponding to the operation execution coordinates are acquired on a first terminal; an interface picture acquired when the interface is operated on a second terminal is intercepted; the interface picture and the recorded picture are subjected to picture recognition, and operation playback coordinates corresponding to the operation execution coordinates in the interface picture are determined according to a picture recognition result; the testing operation is executed on the tested application program on an interface of the second terminal according to the operation playback coordinates. With the adoption of the method, the device and the system for testing the application program, the problem that a software testing result is inaccurate due to the fact that a record and playback method used for testing software in the prior art cannot adapt to terminals with different resolutions is solved, and the operation execution coordinates can be acquired accurately, so that the testing operation can be accurately performed on the second terminal, and an accurate testing result of the application program can be acquired.

Brain machine interface system based on human face recognition specific wave N170 component

The present invention relates to a brain-machine interface system based on face recognition specific wave N170 component, which implements sorting of facial pictures and object pictures, and comprises a picture stimulator, a cortical electric signal collector, a face recognition specific wave N170 detector, and a picture sorter. Pictures to be sorted are presented by the visual picture stimulator as visual stimulations to a user, and the cortical electric signals of the user generated in response are recorded and subjected to amplification and A/D conversion, and then processed and analyzed by the face recognition specific wave N170 detector, whereby a determination is made whether the collected cortical electric signals contain specific wave N170 component related to facial picture stimulation, and accordingly, the cortical electric signals are transformed into picture sorting control commands for identifying facial pictures and object pictures. The advantages of the present invention are: the present invention utilizes the specific cortical electric signal N170 component generated in the facial picture recognition process in response to facial picture stimulations, and employs an effective online feature extraction and sorting algorithm in the cortical electric signal analyzer; therefore, the discrimination ratio of the system is increased. The present invention provides a novel means for persons who suffer from dyskinesia but can think normally to communicate with and control the external environment.
