Man-machine motion interaction system and method based on expression recognition

The invention provides a man-machine motion interaction system and method based on expression recognition. The system comprises an image acquisition module, an image processing module, an expression recognition module, a man-machine interaction module and a storage module. The image acquisition module acquires a facial image; the image processing module processes the acquired facial image for graying, size adjustment and the like; an expression in the facial image is recognized by means of expression recognition; the man-machine interaction module feeds back to a user according to the facial expression; the statistical and storage module analyzes mental state of the user at this moment and records the mental state; meanwhile, a statistical query function is provided for the user. After applied to intelligent equipment, the system is capable of providing specific humanized responses so that the equipment can be more intelligent; when applied to mental care robots, the system is capable of capturing patients' expressions to allow for simple and effective communication with patients, so that the patients with mental illnesses can be supervised safely in real time, and effective data basis for treatment is provided for doctors.

Method and device of adjusting facial beautification effect in camera photographing in real time

The invention discloses a method of adjusting a facial beautification effect in camera photographing in real time, which is applied to an intelligent mobile terminal provided with a back touch function and a front pick-up lens. The method comprises the following steps: S1, entering an image preview interface of a camera and obtaining real-time face image information; S2, establishing a real-time facial beautification function mapping relation list including mapping relation of gesture operation information and a facial beautification function effect and a conversion rule of a finger sliding distance and facial beautification effect parameters; S3, obtaining the gesture operation information of a user; S4, converting a gesture operation event to a parameter size adjustment event of the facial beautification function effect; S5, adjusting a preview image in real time through the obtained facial beautification function effect parameters; and S6, photographing through photographic equipment according to the selected facial beautification effect parameters. According to the method and the device, through providing a photographing mode capable of adjusting the facial beautification effect in real time, when the user takes a selfie, a modification process of the facial beautification effect can be seen in real time, so that the user experience of photo retouching and facial beautification functions is improved.

Multiple information encrypted two-dimensional code anti-counterfeiting method

The invention relates to a multiple information encrypted two-dimensional code anti-counterfeiting method, which comprises the steps of generating an encrypted serial number through carrying out algorithm encryption on a digital serial number, acquiring an image containing the encrypted serial number by using a screenshot method, carrying out dimension adjustment, image graying and image scrambling processing on the encrypted serial number to acquire a secret image, inserting the secret image into a two-dimensional image by using a bit operation method by taking a two-dimensional code as a carrier so as to acquire a mixed two-dimensional code which is finally used for printing; and acquiring the encrypted serial number through extracting the secret image in the two-dimensional code and carrying out anti-scrambling processing when information verification is carried out, then acquiring a decrypted serial number by adopting a decryption algorithm, and distinguishing authenticity of information through comparing the decrypted serial number with an original serial number. The method provided by the invention realizes two-dimensional anti-counterfeiting by combining simple information algorithm encryption and a method of image conversion and image concealing. The method is easy to implement, does not influence the information capacity of the two-dimensional code, and has very good anti-counterfeiting performance.
