In order to enable a user to have better watching experience when the video image is played on the video playing device under the condition that the video acquisition specification and the video playing specification are not matched, the key feature extraction operation can be performed on the video image, and then the target video image is generated according to the key feature, so that when the target video image is played on the video playing device, the key content of the video image can be clearly displayed, the non-key content is selectively ignored, and the watching of the user is not influenced.
Optionally, the key feature extraction operation is performed on the video image according to the video acquisition specification and the video playing specification, and the key feature extraction operation includes: carrying out target identification on the video image to obtain a plurality of target objects; respectively acquiring a first video image length corresponding to a video acquisition specification and a second video image length corresponding to a video playing specification; acquiring a target to be played from a plurality of target objects according to a first ratio obtained by dividing the length of the second video image by the length of the first video image; and performing key feature extraction operation on the obtained target to be played.
After the video image is obtained, the target object in the picture is firstly identified, and the modes which can be adopted include face identification, target matching, or classification identification of a neural network model. After the target object is identified, the category of the target object may also be labeled. Then, acquiring a first video length corresponding to a video acquisition specification, wherein the video acquisition specification is 16:9, and the first video length is 16; and then acquiring a second video length corresponding to the video playing specification, wherein the video playing specification is 9:16, and the second video length is 9. Then, a first ratio of the second video length to the first video length is calculated, that is, P1 is 9/16 < 1, which indicates that the first video length is greater than the second video length, the target objects cannot be completely displayed on the playing device in the horizontal direction, and only a part of the target objects can be selected from all the target objects for display.
Referring to fig. 1D, fig. 1D is a schematic diagram of obtaining a target to be played according to an embodiment of the present disclosure, as shown in (a) of fig. 1D, when a first video length is greater than a second video length, that is, a first ratio is greater than 1, as shown in (b) of fig. 1D, a central line of a video image may be overlapped with a central line of the second video length, and a target object within the second video length range is obtained from the video image as the target to be played. Alternatively, as shown in (c) in fig. 1D, a main target object of the plurality of target objects may be acquired, and a center line of the main target object may be overlapped with a center line of the second video length, and a target object within the second video length range may be acquired from the video image as the target to be played. If the center line of the main target object is superposed with the center line of the second video length, the boundary of the second video length is larger than the boundary of the first video length, the boundary of the second video length is automatically adjusted to be superposed with the boundary of the first video length, and then the target object in the second video length range with the superposed boundary of the first video length as a starting point is obtained as the target to be played. And after the target to be played is obtained, performing key feature extraction operation on the target to be played.
Optionally, the performing key feature extraction operation on the obtained target to be played includes: acquiring the number of preset key features of a target to be played; and performing key feature extraction operation on a plurality of features of a plurality of targets to be played according to the preset key feature number.
The target to be played in the video image comprises a plurality of features, for the character, the posture, the clothing, the height, the face, the body part, the clothes and the like of the character, for the plant, the plant structure, the flower shape, the color, the size, the height and the like, for the building, the height, the color, the shape structure and the like, and each target to be played is subjected to feature extraction to obtain a plurality of corresponding features. Because the width (or height) of the video image is different from the width (or height) of the video playing device, all the features of the video image cannot be displayed in detail on the video playing device, and therefore, an important feature extraction operation needs to be performed on a target to be played, and the important features are displayed in detail. The preset number of key features may be selected by a user, randomly preset by a system, or obtained by analyzing a target.
Optionally, the obtaining of the preset key feature number of the target to be played includes: determining a first classification category of the target to be played according to the material attributes of the target to be played, wherein the material attributes comprise characters, animals, plants and non-living things; determining a second classification category of the target to be played according to the space area of the target to be played; and obtaining the number of preset key features corresponding to the target to be played according to the first classification category and the second classification category by contrasting a key feature list.
For people, animals, plants, and non-living things except animals and plants, the number of important features that they need to display are different, for example, for people, people's face, posture and actions are the most important to display, for plants, flowers, fruits, etc. are the most important to display, for non-living things, the whole structure is the most important to display, and therefore, the first classification category of the object to be played needs to be determined first. After the first classification type is determined, a second classification type is determined according to the space area of the target to be played, if the proportion of the space area in the video image is larger than the first area proportion, the number of first-gear preset key features corresponding to the first classification type is obtained, the number of the first-gear preset key features corresponding to the first classification type is smaller than the first area proportion and larger than the second area proportion, the number of second-gear preset key features corresponding to the first classification type is obtained, the number of the second-gear preset key features corresponding to the first classification type is smaller than the second area proportion, and the number of third-gear key features corresponding to the first classification type is obtained, wherein the number of the first-gear preset key features is larger than the number of the second-gear preset key features and larger than the number of the third-gear key features.
Optionally, before obtaining the key features of the plurality of features according to the video capture specification and the video playback specification, the method further includes: extracting the characteristics of the target to be played to obtain a plurality of characteristics corresponding to the target to be played; sorting the plurality of features according to the importance degree to obtain a feature sorting result; performing key feature extraction operation on the obtained target to be played, comprising the following steps: and acquiring key features corresponding to the target to be played from the feature sequencing result according to the preset key feature number.
For each object to be played, the importance degrees of the plurality of features are different, and for the person, when the video image is displayed, the importance degrees of the plurality of features are ranked as follows: height, human face, clothing and apparel; for a flower, the importance of the features is ranked as: plant structure, height, flower size, shape, color; for buildings, the importance of a number of features is ranked as: height, shape structure, color. After determining the number of important features obtained from the plurality of features of the target to be played, it is also necessary to determine which features are specifically obtained as important features.
And sequencing the plurality of features according to the importance degree, acquiring the feature sequencing result, and acquiring the feature with the top preset key feature number in the sequencing result as the key feature, thereby finishing the key feature extraction process of the target to be played.
104. And generating a target video image according to the key characteristics, wherein the target video image is used for playing through the video playing equipment.
After the key features are obtained, the target video image can be generated according to the key features. In the target video image, the display of the key features is mainly ensured, and non-key features except the key features can be properly ignored.
Optionally, generating the target video image according to the key features includes: acquiring a first video image width corresponding to a video acquisition specification and a second video image width corresponding to a video playing specification, and calculating a second ratio obtained by dividing the second video image width by the first video image width; when the second ratio is smaller than 1, acquiring non-key features except the key features in the plurality of features corresponding to the target object to be played; narrowing the width of the non-key features according to a second ratio to obtain updated non-key features; forming a third video image corresponding to the target object to be played by the key features and the updated non-key features; determining whether the third video image width is greater than the second video image width; if so, repeatedly carrying out width reduction on the non-key features according to a second ratio, and obtaining updated non-key features again; and the process of forming a third video image of the target object to be played by the key features and the updated non-key features until the width of the third video image is determined to be not more than the width of the second video image, and taking the third video image as the target video image.
The first video image width corresponding to the video capture specification and the second video image width corresponding to the video playing specification are different, and a second ratio obtained by dividing the second video image width by the first video image width is calculated, for example, the first video image width is 16, the second video image width is 9, and then the second ratio P2 is 9/16. When the second ratio is smaller than 1, it is indicated that the second video width is smaller than the first video width, and when the target video image is obtained, the features corresponding to the original video image are mainly compressed. Then, non-key features except for the key features in the plurality of features corresponding to the target object to be played are obtained, and then the width of the non-key features is reduced according to a second ratio to obtain updated non-key features; and combining the key features and the updated non-key features to generate a third video image corresponding to the target object to be played, and then determining whether the width of the third video image is greater than that of the second video image, wherein the width of the obtained third video image may be greater than that of the second video image or less than or equal to that of the second video image because only the non-key features are highly compressed and the key features keep the original size unchanged. If the width of the third video image is determined to be larger than the width of the second video image, the third video image needs to be compressed again, the non-key features are reduced again according to the second ratio, the subsequent process of forming key features to generate the third video image is repeated, the width of the obtained third video image is worth determining to be not larger than the width of the second video image, the obtained video image can be completely displayed on a screen of video playing equipment, and therefore the obtained third video image is used as a target video image. Referring to fig. 1E, fig. 1E is a schematic diagram of obtaining a target video image according to an embodiment of the present application, as shown in fig. 1E, a left image is a video image obtained by a doorbell camera, a target to be played is identified as a person, and a corresponding key feature of the person is obtained as a face, so that the face is kept unchanged, and other features are correspondingly compressed to obtain a right target video image. Thus, the human face can be clearly displayed, and the characteristics of the human face can be correspondingly compressed.
Optionally, generating the target video image according to the key features includes: when the second ratio is larger than 1, obtaining key features corresponding to the target object to be played; amplifying the width of the key features according to a second ratio to obtain updated key features; the fourth video image corresponding to the target object to be played is composed of the updated key features and the non-key features, wherein the non-key features are the features except the key features in the plurality of features corresponding to the target object to be played; determining whether the fourth video image width is less than the second video image width; if so, repeatedly amplifying the important point features according to the second ratio to obtain updated important point features again; and a process of forming a fourth video image of the target object to be played by updating the key features and the non-key features until the width of the fourth video image is determined to be not less than the width of the second video image, and taking the fourth video image as the target video image.
When the second ratio is greater than 1, it is indicated that the second video width is greater than the first video width, and when the target video image is obtained, the features corresponding to the original video image are mainly expanded. However, if all features are extended identically, on one hand, because only the width of the video image is stretched and the length is not changed, the new video image obtained will be severely deformed, which affects the visibility, and on the other hand, the definition of the video image will also be affected. Therefore, the key features are obtained, the width of the key features is enlarged according to the second ratio to obtain updated key features, a fourth video image corresponding to the target object to be played is formed by the updated key features and the non-key features, and if the width of the fourth video image is smaller than that of the second video image, the width of the key features is enlarged again until the width of the obtained fourth video image is not smaller than that of the second video image. Because the video image is not reduced in length, the width is only enlarged, so that key features can be displayed in a key mode, the video image can not be seriously deformed, and the watching experience of a user is improved.
Therefore, in the embodiment of the application, the adjustment mode of the key features or the non-key features is determined by performing key feature extraction operation on the video images and then dividing the width of the second video image by the width of the first video image to obtain a second ratio, so that the flexibility of adjusting the features of the video images is increased, and the playing quality of the composed target video images is ensured.
And after the target video image is obtained, the target video image can be played on video playing equipment. The width of the obtained target video image is correspondingly adjusted according to the width of the video playing device, and the obtained target to be played is determined according to the length of the video playing device, so that the target video image can be well adapted to the video playing specification of the video playing device.
Therefore, in the embodiment of the application, firstly, the video image is collected through the doorbell camera, and the video collection specification of the doorbell camera is obtained; then acquiring a video playing specification of the video playing equipment; performing key feature extraction operation on the video image according to the video acquisition specification and the video playing specification, and generating a target video image according to key features; and finally, playing the target video image on the video playing equipment. In the process, the key features of the video images are extracted, and the target video images are generated according to the key features, so that the display definition of the key features in the video images is guaranteed, the display rationality of the target video images is improved, and the watching experience of users is improved.
