Fig. 1 is a schematic diagram of one application scenario of a method of displaying an image of some embodiments of the present disclosure.
In the application scenario of fig. 1, the electronic device 101 extracts audio information and a to-be-processed image from a to-be-processed video. The image to be processed comprises two persons, and the audio information is voice information sent from a first person to a second person. The electronic device 101 may query the target pronunciation information 102 from the audio information and the target object image 103 corresponding to the target pronunciation information 102. The target pronunciation information 102 may be "watch movie", "shopping", etc. The target object image 103 may be an ear image of the second person. Then, the electronic device 101 may establish a correspondence relationship between the target pronunciation information 102 and the target object image 103, which may be used to represent that "watch movie", "visit" and "walk" act on the ear of the second person. To increase the visual effect when the user views the video to be processed, the electronic device 101 may set the target image 104 of the target object image 103. The target image 104 may be a pair of rabbit ears, which may exaggeratedly indicate that the second person is listening to the voice information of the first person, thereby enhancing the visual impression of the user. When the target pronunciation information 102 is played (i.e., triggered) in the video to be processed, the electronic device 101 may display the target image 104.
It should be understood that the number of electronic devices 101 in fig. 1 is merely illustrative. There may be any number of electronic devices 101, as desired for implementation.
With continued reference to fig. 2, fig. 2 illustrates a flow 200 of some embodiments of a method of displaying an image according to the present disclosure. The method for displaying the image comprises the following steps:
In some embodiments, the execution subject of the method of displaying an image (e.g., the electronic device 101 shown in fig. 1) may extract audio information and an image to be processed from a video to be processed by a wired connection or a wireless connection. It should be noted that the wireless connection means may include, but is not limited to, a 3G/4G/5G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a uwb (ultra wideband) connection, and other wireless connection means now known or developed in the future.
The execution subject may first obtain the video to be processed. The video to be processed may be a real-time video containing a face image, or may be a non-real-time video containing a face image. The face image may be a human face image, an animal face image, a statue face image, or the like. The execution subject may extract audio information and an image to be processed in the video to be processed. The audio information may include at least one pronunciation information. The enunciated information may be various audio, for example, the enunciated information may be human voice audio, bird audio, automobile engine audio, ambient noise, or the like. The image to be processed may include an object image corresponding to pronunciation information in the at least one piece of pronunciation information. The performing subject may perform image recognition on the image to be processed, first recognize a head image of a person, an animal or a statue in the image to be processed, and then specifically recognize various parts (such as eyes, a nose, a mouth, etc.) included in the head image. The pronunciation information may be various, some of which may have an object image and some of which may not have an object image. For example, if the pronunciation information is speech uttered by the first person to the second person, the object image may be an ear of the second person. If the pronunciation information is environmental noise, there may be no object image.
As can be seen from the above description, some pronunciation information may have corresponding object images. For convenience of analysis, the execution subject may set pronunciation information of the presence object image as target pronunciation information and set the object image as a target object image corresponding to the target pronunciation information. Thereafter, the executing body may establish a correspondence between the target pronunciation information and the target object image. It should be noted that one target pronunciation information may have a plurality of target object images. For example, the video to be processed is a student class video, one teacher gives a lecture, and a plurality of students attend a lecture. Correspondingly, the target pronunciation information may be the voice of the teacher, and the target object image may be an ear image of each student. There may be one target object image for a plurality of target pronunciation information. For example, a plurality of students simultaneously take lessons and a teacher listens. Correspondingly, the target pronunciation information is the voice of each student, and the target object image may be an image of the teacher's ear. It is also possible to use a plurality of target object images in the plurality of target utterance information. For example, multiple people sing a song at the same time, and multiple listeners listen to the song. Correspondingly, the target pronunciation information is singing voice of each person, and the target object image is an ear image of each listener. Therefore, the information transmission relation is determined, and the efficiency of obtaining information by a user is improved.
In order to deepen the user's experience of watching a video, the execution subject may set a target image for each target object image. The target image may be an image obtained by performing image processing on the target object image. For example, the target image may be an enlarged image, a deformed image, or the like of the target object image. The target image may also be a substitute image for the corresponding target object image. As in fig. 1, the "ear" of the second individual is characterized by a "rabbit ear". Further, the target image may also be an image to which other special effects (e.g., train whistle, flashing stars, etc.) are added.
And step 204, in response to that the target pronunciation information in the audio information is triggered, displaying a target image corresponding to the target pronunciation information in the video to be processed.
When the target pronunciation information in the audio information is triggered (such as playing the target pronunciation information), the execution main body can display a target image corresponding to the target pronunciation information in the video to be processed. Therefore, the user can clearly determine the information transfer relationship between the target pronunciation information and the target object image, the visual effect is enhanced, and the accuracy and the effectiveness of the user for acquiring the information in the video to be processed are improved.
According to the method for displaying the image disclosed by some embodiments of the disclosure, firstly, the audio information and the image to be processed are extracted from the video to be processed, and then the corresponding relation between the target pronunciation information contained in the audio information and the target object image contained in the image to be processed is established, so that the transfer relation of the information is clarified. And then, setting a target image corresponding to each target object image contained in the image to be processed, so that the experience of watching the video by the user is deepened. And finally, when the target pronunciation information in the audio information is triggered, displaying a target image corresponding to the target pronunciation information in the video to be processed. The method and the device can enable the user to clarify the information transfer relation between the target pronunciation information and the target object image, enhance the visual effect and are beneficial to improving the effectiveness of the user in obtaining the information in the video to be processed.
With continued reference to fig. 3, fig. 3 illustrates a flow 300 of some embodiments of a method of displaying an image according to the present disclosure. The method for displaying the image comprises the following steps:
The content of step 301 is the same as that of step 201, and is not described in detail here.
In some optional implementations of some embodiments, the extracting the audio information and the image to be processed from the video to be processed may include the following steps:
the method comprises the following steps of firstly, identifying at least one object content in the image to be processed.
The execution subject may recognize at least one object content in the image to be processed through a plurality of image recognition methods. Wherein the object content includes at least one of: face image, mouth image, ear image.
And secondly, setting a contour line for the object content in the at least one object content to obtain an object image.
In order to be able to accurately display object contents, the execution body may set an outline for each object content. The contour lines are used to identify the boundaries of the object content. That is, the object image is an image obtained by adding a contour line to the object content.
Generally, the video to be processed may include a timestamp, and the timestamp may be used to mark a playing time of the video to be processed, and may also be used to mark a corresponding relationship between the audio information and the image to be processed. The audio information typically contains pronunciation information that occurs at a corresponding time. Accordingly, the execution subject can determine the trigger time of the pronunciation information from the time stamp. Wherein, the trigger time can be used for representing the time of playing the pronunciation information. For example, if the time stamp corresponding to the trigger time of the sound information is 1 minute 20 seconds, the sound information is played at 1 minute 20 seconds.
In order to establish the correspondence relationship between the pronunciation information and the object image, the execution subject may inquire the correlation between the pronunciation information and the object image in time. Generally, after the pronunciation information is played, the object image corresponding to the pronunciation information changes accordingly. For example, when the first person speaks a joke and the second person hears a joke, the target pronunciation information is the audio of the joke, and the target subject image may be the mouth image and the ear image of the second person. Although the ear images have no obvious deformation, the audio is firstly transmitted into the ears and then understood by the brain to control the mouth to deform. Therefore, the ear image can also be regarded as the target object image.
After the target pronunciation information and the target object image are determined, the execution subject may establish a correspondence between the target pronunciation information and the target object image. For example, when the target pronunciation information is played for a set time (for example, 2 seconds), the target object image may be displayed.
The contents of steps 305 to 306 are the same as those of steps 203 to 204, and are not described in detail here.
Fig. 3 illustrates an embodiment, in which a target object image corresponding to target pronunciation information is determined by a timestamp of a video to be processed. Therefore, the corresponding relation between the target pronunciation information and the target object image is established, and the accuracy of displaying the target image when the target pronunciation information is triggered is improved.
With continued reference to fig. 4, fig. 4 illustrates a flow 400 of some embodiments of a method of displaying an image according to the present disclosure. The method for displaying the image comprises the following steps:
And 403, amplifying the target object image according to each amplification factor in the preset amplification factor sequence to obtain a target image sequence.
The execution subject may enlarge the target object image to obtain a target image corresponding to the target object image. When the target audio information is played, the user sees the target image with the target object image enlarged. Therefore, the accuracy and effectiveness of information acquisition when the user views the video to be processed are improved. Specifically, the execution main body may amplify the target object image according to each magnification in a preset magnification sequence, so as to obtain a target image sequence. Wherein the magnifications in the magnification sequence may be sequentially increased. Further, each of the magnification in the magnification sequence may correspond to a volume amplitude of the utterance information.
As is apparent from the above description, the target image sequence includes the target image in which the target object image is enlarged at each magnification in the preset magnification sequence. Based on this, the execution body may establish a correspondence relationship between each magnification in the magnification sequence and the volume amplitude of the utterance information. The execution subject may determine a target volume amplitude of the target pronunciation information, and further select a target image corresponding to the target volume amplitude from the target image sequence for display. Thus, the corresponding relation between the target pronunciation information and the target object is established through the volume amplitude. When the target volume amplitude is smaller, the displayed target image is smaller; when the target volume amplitude is larger, the displayed target image is also larger. That is, the target image is different in size for different volume amplitudes, and the visual experience of the user viewing the target image is also different. Therefore, the corresponding relation between the target pronunciation information and the target image can be vividly displayed, and the accuracy and the effectiveness of information acquisition when a user watches the video to be processed are improved.
In some optional implementations of some embodiments, the selecting, based on the target volume amplitude, a corresponding target image from the target image sequence for display may include:
in the first step, an image axis and a rotation angle are set for the target image in response to the target volume amplitude being greater than a set volume threshold.
When the target volume amplitude is greater than the set volume threshold, the target volume amplitude may be considered to have exceeded the normal volume amplitude to the user's auditory effect. At this time, the execution body may set an image axis and a rotation angle for the target image. Wherein the image axis may be a line through the target image. The rotation angle may be any angle. Typically, the rotation angle may take a value between 10 ° and 30 °. The rotation angle may be set based on the image axis. For example, the image axis may be an edge of the rotation angle, may be an angle bisector of the rotation angle, and the like, according to actual needs.
And a second step of generating a first image and a second image based on the target image.
The executing subject may generate a first image and a second image from the target image. The first image and the second image may be the same as the target image. A first image axis included in the first image and a second image axis included in the second image may correspond to an image axis of the target image, respectively.
And thirdly, setting a first image axis of the first image to coincide with one side of the rotation angle, and setting a second image axis of the second image to coincide with the other side of the rotation angle.
The executive body may coincide the first image axis and the second image axis at two sides of the rotation angle, respectively. In this way, the positional relationship and the angular relationship of the first image and the second image can be determined. Further, the first image and the second image may be arranged in angular registration. The angle coincidence setting may be that when two sides of the rotation angle coincide, the first image and the second image also coincide.
And fourthly, alternately displaying the first image or the second image according to a set frequency.
The execution body may set a set frequency such that the first image and the second image are alternately displayed. Therefore, when the target volume amplitude is larger than the set volume amplitude, the target image can display a dynamic effect. For example, the target pronunciation information is a joke, and the target image is an ear image. And when the target volume amplitude of the target pronunciation information is larger than the set volume amplitude, the ear images are alternately displayed to have a vibration effect. Therefore, the user experience can be deepened, and the accuracy and effectiveness of the user for obtaining the information are improved.
In some optional implementations of some embodiments, the displaying, in response to triggering of target pronunciation information in the audio information, a target image corresponding to the target pronunciation information in the to-be-processed video may include:
firstly, acquiring a real-time image of a target object corresponding to the target pronunciation information.
In practice, the object image in the object to be processed may change over time. In order to be able to present the object image in real time. The execution subject may obtain a real-time image of the target object of the target pronunciation information. The execution body can acquire a real-time image of the target object at set time intervals. That is, the target real-time image may be a target image within a set time period after the time when the target pronunciation information is triggered. The real-time target object image can be visually understood as an image obtained by amplifying the object image in a set time period in real time. In contrast, the target image in fig. 3 is a relatively still image.
And secondly, dynamically generating a real-time target image of the real-time target object image according to the target volume amplitude of the target pronunciation information.
After the real-time target object image is obtained, the execution main body can dynamically generate the real-time target image of the real-time target object image according to the target volume amplitude of the target pronunciation information. Therefore, the user can acquire the real-time target image, and the timeliness and effectiveness of the user for acquiring information are improved.
In some optional implementations of some embodiments, the displaying, in response to triggering of target pronunciation information in the audio information, a target image corresponding to the target pronunciation information in the to-be-processed video may include:
firstly, determining a connection area between a target object image corresponding to the target image and the image to be processed.
The target image is an enlarged view of the target object image. The execution subject may determine a connection region between the target object image corresponding to the target image and the to-be-processed image. For example, if the target object image is an ear image, the connection region may be an image region having a size set between the ear image and the head image in the image to be processed.
And secondly, performing transition processing on the connection area based on the image to be processed and the target image.
The execution subject can perform transition processing on the connection region through the image to be processed and the target image. The transition treatment comprises at least one of the following: color transitions, line transitions, etc. Therefore, the target image and the to-be-processed image can be combined more naturally, the display effect of the to-be-processed image is improved, the watching experience of a user is deepened, and the accuracy and effectiveness of the user in obtaining information are improved.
