As shown in fig. 4, in the embodiment of the present application, the application framework layer includes a manager (Managers), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used for interacting with all activities running in the system; the Location Manager (Location Manager) is used for providing the system service or application with the access of the system Location service; a Package Manager (Package Manager) for retrieving various information related to an application Package currently installed on the device; a Notification Manager (Notification Manager) for controlling display and clearing of Notification messages; a Window Manager (Window Manager) is used to manage the icons, windows, toolbars, wallpapers, and desktop components on a user interface.

In some embodiments, the activity manager is to: managing the life cycle of each application program and the general navigation backspacing function, such as controlling the exit of the application program (including switching the user interface currently displayed in the display window to the system desktop), opening, backing (including switching the user interface currently displayed in the display window to the previous user interface of the user interface currently displayed), and the like.

In some embodiments, the window manager is configured to manage all window processes, such as obtaining a display size, determining whether a status bar is available, locking a screen, intercepting a screen, controlling a display change (e.g., zooming out, dithering, distorting, etc.) and the like.

In some embodiments, the system runtime layer provides support for the upper layer, i.e., the framework layer, and when the framework layer is used, the android operating system runs the C/C + + library included in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (such as fingerprint sensor, temperature sensor, touch sensor, pressure sensor, etc.), and so on.

In some embodiments, the kernel layer further comprises a power driver module for power management.

In some embodiments, software programs and/or modules corresponding to the software architecture of fig. 4 are stored in the first memory or the second memory shown in fig. 2 or 3.

In some embodiments, taking the magic mirror application (photographing application) as an example, when the remote control receiving device receives a remote control input operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into an original input event (including information such as a value of the input operation, a timestamp of the input operation, etc.). The raw input events are stored at the kernel layer. The application program framework layer obtains an original input event from the kernel layer, identifies a control corresponding to the input event according to the current position of the focus and uses the input operation as a confirmation operation, the control corresponding to the confirmation operation is a control of a magic mirror application icon, the magic mirror application calls an interface of the application framework layer to start the magic mirror application, and then the kernel layer is called to start a camera driver, so that a static image or a video is captured through the camera.

In some embodiments, for a display device with a touch function, taking a split screen operation as an example, the display device receives an input operation (such as a split screen operation) that a user acts on a display screen, and the kernel layer may generate a corresponding input event according to the input operation and report the event to the application framework layer. The window mode (such as multi-window mode) corresponding to the input operation, the position and size of the window and the like are set by an activity manager of the application framework layer. And the window management of the application program framework layer draws a window according to the setting of the activity manager, then sends the drawn window data to the display driver of the kernel layer, and the display driver displays the corresponding application interface in different display areas of the display screen.

In some embodiments, as shown in fig. 5, the application layer containing at least one application may display a corresponding icon control in the display, such as: the system comprises a live television application icon control, a video on demand application icon control, a media center application icon control, an application center icon control, a game application icon control and the like.

In some embodiments, the live television application may provide live television via different signal sources. For example, a live television application may provide television signals using input from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

In some embodiments, a video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various applications for multimedia content playback. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

In some embodiments, an application center may provide storage for various applications. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on the smart television. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

In some embodiments, the controller 250 controls the operation of the display device 200 and responds to user operations associated with the display 275 by running various software control programs (e.g., an operating system and/or various application programs) stored on the memory 260. For example, control presents a user interface on a display, the user interface including a number of UI objects thereon; in response to a received user command for a UI object on the user interface, the controller 250 may perform an operation related to the object selected by the user command.

The software programs stored on memory 260 may include an image recognition program by which controller 250 operates to recognize objects in a particular image, including, but not limited to, people (e.g., stars), objects, and the like. Illustratively, a user opens an image recognition program, uploads an image to be recognized to a server through the image recognition program, and finally receives a recognition result returned by the server. For another example, when the user watches a video program using the video playing software, an instruction for identifying a currently playing picture is input by operating a key provided in the playing interface, and the device executes a screenshot operation to intercept the currently playing video picture in response to the instruction, and then identifies the intercepted video picture.

In an implementation scenario in which people in an image are identified, people information is generally matched by identifying faces in the image. However, due to the influence of the size of the face area and the size of the image resolution, if the size of the face area in the image is small or the image resolution is low, the feature extraction points are insufficient, and therefore the recognition is not possible or the recognition is erroneous.

In order to solve the above problems, the present application provides an image recognition method, where after an image to be processed is acquired, it is first determined whether the image to be processed satisfies a preset recognition condition, and if the image to be processed does not satisfy the preset recognition condition, the image to be processed is processed into an image satisfying the preset recognition condition, and then recognition is performed, so as to improve accuracy of human recognition in the image.

The image recognition method provided by the embodiment of the present application includes, but is not limited to, application to the display device shown in fig. 1 to 5, application to other handheld devices capable of providing voice and data connectivity and having wireless connection function, or application to other processing devices capable of connecting to a wireless modem, such as a mobile phone (or referred to as "cellular" phone) and a computer having a mobile terminal, and application to portable, pocket, handheld, computer-embedded or vehicle-mounted mobile devices, which exchange data with a wireless access network.

When the method is applied to a display device, its execution subject may be the controller 250. Accordingly, the present application also provides a display device based on the display device shown in fig. 1-5, wherein the controller 250 is configured to perform some or all of the steps of the image recognition method provided by the present application. As shown in fig. 6, the method may include:

step 601, acquiring an image to be processed.

The image to be processed may be an image pre-stored in the local display device, or an image stored in an external device connected to the display device, such as a USB device, or a current playing image of the display device captured in response to an identification instruction input by a user in some operation scenes, for example, in a scene in which the user uses video playing software to watch a video program, the identification instruction is input through a key or voice, and the display device performs a screenshot operation on the playing video image, so as to obtain the image to be processed.

Step 602, when the image to be processed and the first target image meet a preset identification condition, acquiring an identification result based on the first target image.

In this embodiment of the application, the first target image is an original image corresponding to a target region in an image to be processed, and in a face recognition scene, the target region may be a face region. After the target area in the image to be processed is detected, a first target image can be obtained by cropping the image to be processed.

Step 603, when the image to be processed and the first target image do not meet the preset identification condition, acquiring an identification result based on a second target image.

In the embodiment of the application, the second target image is an image which is obtained according to the first target image and meets the preset identification condition, and further, the second target image corresponds to the target area in the image to be processed.

In some embodiments, if the resolution of the image to be processed is lower than the preset resolution or the size of the first target image is smaller than the preset size, the image to be processed and the first target image do not satisfy the preset identification condition; and if the resolution ratio of the image to be processed is not lower than the preset resolution ratio and the size of the first target image is not smaller than the preset size, the image to be processed and the first target image meet the preset identification condition.

For example, whether the resolution of the image to be processed is lower than a preset resolution is judged, if the resolution of the image to be processed is lower than the preset resolution, it is judged that the image to be processed and the first target image do not satisfy a preset identification condition, if the resolution of the image to be processed is not lower than the preset resolution, it is judged that the size of the first target image is lower than a preset size, if the size of the first target image is lower than the preset size, it is judged that the image to be processed and the first target image do not satisfy the preset identification condition, and if the size of the first target image is not lower than the preset size, it is judged that the image to be processed and the first target image satisfy the preset identification condition.

For example, the predetermined resolution may be 480P, and the predetermined size may be 30 pixels × 30 pixels.

In some embodiments, the first target image is processed by using a Super Resolution (SR) technique, and a second target image with a Resolution not lower than a preset Resolution may be obtained. The Super Resolution (SR) technique is a technique of taking a Low Resolution image (LR) with blur, noise, and spectrum aliasing as an input and fusing a High Resolution (HR) image by a signal processing technique. The SR technology can overcome the resolution limit of an image system, improve the quality of most images in image processing and has the characteristic of low cost. It should be added that the second target image can be obtained by processing the first target image with the image super-resolution algorithm and the model in the prior art, including but not limited to a reconstruction-based method, a learning-based method, and the like, such as the generation of super-resolution pictures by a cognitive generic Networks.

Fig. 7 is a possible first target image and a second target image exemplarily shown in the present application, where (a) shows the first target image, and (b) shows the second target image corresponding to (a), and it can be seen that pixels of the first target image are very low and do not satisfy a feature point extraction requirement required for face recognition, and pixels of the second target image are high and satisfy a feature point extraction requirement required for face recognition.

In some embodiments, after the display device acquires the image to be processed, the data corresponding to the image to be processed is sent to the server, where the data corresponding to the image to be processed at least includes data for enabling the server to acquire the first target image and data for enabling the server to acquire the resolution of the image to be processed. The data for determining the resolution of the image to be processed may be a resolution parameter of the image to be processed, or an identifier indicating a definition mode configured when the display device plays the image to be processed, such as a top-speed mode, a smooth mode, a standard mode, a high-definition mode, and the like, so that the server determines the definition mode according to the identifier of the definition mode, and further determines the resolution of the image to be processed.

In the embodiments, after receiving data corresponding to an image to be processed sent by a display device, a server detects a target area, namely a face area, in the image to be processed on the one hand, and cuts the image to be processed according to the detected target area to obtain a first target image. Then, the server judges whether the first target image meets a preset identification condition according to the resolution of the image to be processed and the size of the first target image. If the first target image meets the preset identification condition, directly extracting the features of the first target image, and matching the extracted feature information with a preset feature information base to obtain an identification result; if the first target image does not meet the preset identification condition, the first target image is processed by using an image Super Resolution (SR) technology to obtain a second target image with the Resolution not lower than the preset Resolution, so that the second target image is subjected to feature extraction, and the extracted feature information is matched with a preset feature information base to obtain an identification result. Finally, the server returns the recognition result based on the first target image or the second target image to the display device.

In other embodiments, after acquiring an image to be processed, a display device controller detects a target area in the image to be processed by running an image recognition program to obtain a first target image; judging whether the resolution of the image to be processed and the size of the first target image meet preset identification conditions or not; if the resolution of the image to be processed and the size of the first target image meet preset recognition conditions, a display device controller extracts features of the first target image, and matches the extracted feature information with a local preset feature information base to obtain a recognition result; and if the image to be processed and the first target image do not meet the preset identification condition, calling an image super-resolution processing program to process the first target image to obtain a second target image, extracting the characteristics of the second target image, and matching the extracted characteristic information with a local preset characteristic information base to obtain an identification result.

For example, the recognition result may be information in the preset feature information library that matches the first target image or the second target image and other information, such as other pictures of the same person, a person profile, related web pages, and the like.

Step 604, the recognition result is displayed in the user interface.

For example, in a scenario where a user views a video program using video playing software, the recognition result is presented in a playing interface.

According to the above embodiments, the present application also provides an image recognition method, which is applied to a server, and as shown in fig. 8, the method may include the following steps:

step 801, receiving data corresponding to an image to be processed sent by a display device.

Step 802, determining the image to be processed and a first target image according to the data corresponding to the image to be processed, where the first target image is an original image corresponding to a target area in the image to be processed.

Step 803, judging whether the image to be processed and the first target image meet preset identification conditions.

If the resolution of the image to be processed is lower than a preset resolution or the size of the first target image is smaller than a preset size, the image to be processed and the first target image do not meet a preset identification condition; and if the resolution ratio of the image to be processed is not lower than the preset resolution ratio and the size of the first target image is not smaller than the preset size, the image to be processed and the first target image meet the preset identification condition.

Step 804, when the image to be processed and the first target image meet a preset identification condition, acquiring an identification result based on the first target image.

Step 805, when the image to be processed and the first target image do not meet the preset identification condition, acquiring an identification result based on a second target image, wherein the second target image is an image meeting the preset identification condition and obtained according to the first target image.

Step 806, returning the recognition result to the display device.
