As touching all-in-one profession has become increasingly sophisticated, smart whiteboard price content also is not limited to simple graphic, but increased to blend more media channels, such as mobile terminal, Web, the introduction of interactive function is becoming more and more attention.
Touch in the future, the content of the all-in-one build also appeared some development trend. Generation and data driven, for example, this type of content is not according to the content of the real-time supply, also contains information and visual elements can be used to project and brand custom database. This type of content can ensure successive refresh rate, constraints, the content update requirements, together to ensure that the policy information will appear to the audience.
In fact, many moments we neglect the artistic touch all-in-one. The environment and the content of the digital art can actually act as a strong, with satisfactory strengthening brand image, consolidate the brand contact with the audience. An obvious trend is that digital art, 3 d environment, photograph and painting will bring touch all-in-one PC content to build more artistic originality, the content of the invention are increasingly moving.
In addition, consider some new skills, for example, can be in resolution, temperature scanning kiosks 4 k, and the future of 8 k, 12 k, etc., can bring brand-new visual experience. Specific circumstances of each appeared as a single synchronous canvas to maximize the use of a good idea. Not only that, the invention subversive content sequence, to ensure the information transmission in succession, and share with the audience abundant, empathy, the visual experience.
Face recognition using the camera or camera collection contains a human face image or video stream, and automatically detecting and tracking human face in the image, and then to detect the human face image to a series of related applications. Technology including image acquisition, feature location, identity validation and search, etc. In simple terms, is to extract the features of a face in the picture, such as high eyebrows, mouth and so on, outdoor digital signage displays and by comparison with the characteristics of the output.
Image size: facial image starts to affect the recognition effect, face image will affect the recognition rate. Non-professional face-recognition cameras common rules of minimum recognize faces for more than 60 * 60 or 100 * 100 pixels. Within the prescribed image size, the algorithm is easier to improve accuracy and recall rate. Image size is reflected in the actual application scenario is face the distance from the camera.
Image resolution: the lower the image resolution is difficult to identify. Comprehensive image resolution image size, directly affect the camera distance. Now 4 k camera to see faces is the longest distance between 10 meters, 7 k camera is 20 meters.
Light environment: the image too dark or light environment will affect the effect smart interactive whiteboard of face recognition. Can from the camera to bring the function of fill light or filter balance light effects, can also use optimization algorithm model light images.
Fuzzy degree: the actual scene mainly focus on solving the motion blur, motion will often cause the face relative to the camera motion blur. Some cameras have the function of anti fuzzy, and under the limited cost, optimization model considering algorithm to this problem.
