in one possible implementation, the contours of the faces may be different due to the different faces, which includes: at least one of the different shapes of the face, the different shapes of the facial organs, the different relative positions of the facial organs, or the different relative positions of the facial organs and the facial edges, and the differences can be manifested by the relative positions between the plurality of facial key points of the face. For example, the shape of a face is different, and the relative positions of a plurality of face edge points of the face are also different; the shape of the facial organ is different, the relative positions of the facial organ edge points are also different, and the like. The relative positions between the plurality of face keypoints are used to represent the target face features.

Optionally, determining a first face sub-feature of the target face region according to the abscissa of the plurality of face key points, wherein the first face sub-feature represents the lateral relative positions of the plurality of face key points; or, according to the ordinate of the plurality of face key points, acquiring a second face sub-feature of the target face region, wherein the second face sub-feature represents the longitudinal relative positions of the plurality of face key points.

The embodiment of the application is only described by taking the example that the target face features comprise a first face sub-feature and a second face sub-feature, wherein the target face features comprise at least one first face sub-feature or at least one second face sub-feature. For example, according to the horizontal coordinates of the face key point 1, the face key point 2 and the face key point 3, a first face sub-feature 1 of the target face area is obtained; and acquiring the first face sub-feature 2 of the target face region according to the horizontal coordinates of the face key points 4, 5 and 6. The first face features include a first face sub-feature 1 and a first face sub-feature 2.

In another possible implementation manner, the audience terminal determines a first distance between the first face key point and the second face key point and a second distance between the first face key point and the third face key point according to the positions of the first face key point, the second face key point and the third face key point; and determining a first ratio between the first distance and the second distance as the target face characteristic. The first face key point, the second face key point and the third face key point are any face key point in the plurality of face key points respectively.

It should be noted that, in the embodiment of the present application, only the determination of the target face feature according to the positions of the 3 face key points is described as an example, in another embodiment, other number of face key points may be adopted to determine the target face feature, for example, the target face feature is determined according to the positions of the 4 face key points; or determining the target face features according to the positions of the 6 face key points. The embodiment of the application does not limit the number of the key points of the human face.

In another possible implementation, the angles of the faces displayed in the live view may change, and for faces with different angles, the detected face key points may also be different, for example, if the face in the live view is the left side face of the anchor, then the face key point of the right side face of the anchor cannot be detected. But at any angle, the face region includes eyes and a bridge of the nose. For example, the left face includes a left eye and the right face includes a right eye, and both the left face and the right face include nose bridges. The nose bridge is located on the middle line of the face, and whether the left face or the right face is detected, the key points of the face on the middle line of the face can be detected.

In order to reduce the influence of the change of the face angle on the determination of the target face characteristics, the target face characteristics are determined by adopting the face key points of the region to which the eyes belong or the face key points of the region to which the facial midline belongs. The audience terminal selects a face key point positioned in the first face subarea or the second face subarea from a plurality of face key points; and determining the target face characteristics of the target face area according to the positions of the selected plurality of face key points. The first face subregion is the region that eyes belong to, and the second face subregion is the region that facial midline belongs to, for example, the first face region includes eyes and region around eyes, and the second face region includes the region that the bridge of the nose is located.

In one possible implementation, the viewer terminal selects a first corner of eye key, a second corner of eye key, and a facial edge key at the same elevation as the lower eyelid key from a plurality of facial key points. Wherein the first corner of eye keypoints and the second corner of eye keypoints belong to the same eye, or belong to different eyes.

In order to obtain the target facial features more accurately, optionally, the first corner-of-eye key point and the second corner-of-eye key point belong to the same eye, the first corner-of-eye key point, the second corner-of-eye key point and the face edge key point are at the same height, and the face edge key point is on the same side as the first corner-of-eye key point and the second corner-of-eye key point, that is, the first corner-of-eye key point and the second corner-of-eye key point belong to the left eye, and the face edge key point is the left face edge point; the first eye corner key point and the second eye corner key point belong to the right eye, and the face edge key point is a right face edge point. For example, referring to fig. 6, the first corner key point is C, the second corner key point is B, and the facial edge key point is a; or the first eye corner key point is D, the second eye corner key point is E, and the face edge key point is F.

In one possible implementation manner, after the viewer terminal selects the first corner key point, the second corner key point and the face edge key point, the target face feature is determined in combination with the above possible implementation manner that the ratio between any two distances is determined as the target face feature. Optionally, the first distance is a lateral distance between the facial edge key point and the second corner key point, the second distance is a lateral distance between the second corner key point and the first corner key point, and a ratio between the first distance and the second distance is determined as the target facial feature; or, the first distance is a lateral distance between the face edge key point and the first eye corner key point, the second distance is a lateral distance between the second eye corner key point and the first eye corner key point, and the ratio between the first distance and the second distance is determined as the target face feature.

For example, referring to fig. 6, if the selected face keypoints are A, B and C, r1=ab/BC is determined, and r1 is determined as the target face feature. Wherein AB is the lateral distance between the facial edge key point A and the second corner key point B, BC is the lateral distance between the second corner key point B and the first corner key point C, and r1 is the ratio between AB and BC. If the selected face key points are D, E and F, determining r1=EF/DE, and determining r1 as the target face feature. Wherein EF is the lateral distance between the facial edge key point F and the second corner key point E, DE is the lateral distance between the second corner key point E and the first corner key point D, and r1 is the ratio between EF and DE.

In another possible implementation, the audience terminal selects a first nose bridge keypoint, a second nose bridge keypoint, and a third nose bridge keypoint from a plurality of face keypoints. For example, referring to fig. 6, the first nose bridge keypoint is G, the second nose bridge keypoint is H, and the third nose bridge keypoint is I.

In one possible implementation, after the audience terminal selects the first nose bridge key point, the second nose bridge key point and the third nose bridge key point, the target face feature is determined in combination with the possible implementation of determining the ratio between any two distances as the target face feature. Optionally, the first distance is a longitudinal distance between the first nose bridge key point and the second nose bridge key point, the second distance is a longitudinal distance between the second nose bridge key point and the third nose bridge key point, and a ratio between the first distance and the second distance is determined as the target face feature; or, the first distance is a longitudinal distance between the first nose bridge key point and the third nose bridge key point, the second distance is a longitudinal distance between the second nose bridge key point and the third nose bridge key point, and the ratio between the first distance and the second distance is determined as the target face feature.

For example, referring to fig. 6, if the selected face key points are G, H and I, r2=gh/HI is determined, and r2 is determined as the target face feature. Wherein GH is the longitudinal distance between the first bridge key point G and the second bridge key point H, HI is the longitudinal distance between the second bridge key point H and the third bridge key point I, and r2 is the ratio between GH and HI.

In another possible implementation manner, the audience terminal obtains face shape parameters of the target face area in response to a selection operation of the target face area, and determines the face shape parameters as the target face features. Wherein the face shape parameters include at least one of an aspect ratio of a face length and a face width, a width ratio of a forehead width and a chin width, a chin angle parameter, or a chin angle parameter.

In one possible implementation manner, under the condition that the face shape parameters comprise the length-width ratio of the face length and the face width, the audience terminal identifies the target face area to obtain the face length and the face width of the target face area; and determining a second ratio between the face length and the face width as the target face characteristic. The face length refers to the longest length in the face area, and the face width refers to the widest width in the face area. For example, referring to fig. 7, where the face width is W and the face length is H, r3=h/W, r3 is determined as the target face feature.

In another possible implementation manner, in the case that the face shape parameter includes a width ratio of a forehead width to a chin width, the audience terminal identifies a target face area, and obtains the forehead width and the chin width of the target face area; a third ratio between forehead width and chin width is determined as the target facial feature. For example, referring to fig. 8, where the forehead width is L1 and the chin width is L2, r4=l1/L2, r4 is determined as the target face feature.

In another possible implementation, in the case that the face shape parameter includes a chin angle parameter, the viewer terminal determines a first line segment corresponding to the first chin key point and the second chin key point, and a second line segment corresponding to the second chin key point and the third chin key point according to the position of the first chin key point, the position of the second chin key point, and the position of the third chin key point, and determines the chin angle parameter according to an included angle between the first line segment and the second line segment. The first jaw key point and the second jaw key point are located at the same height, the third jaw key point is the top point of the jaw key points, namely the third jaw key point is the key point located at the lowest position of the jaw key points. For example, referring to fig. 9, the first chin key point is a, the second chin key point is B, the third chin key point is C, the first line segment is AB, the second line segment is BC, r5=tan=abc, the tangent r5 of the ++abc is determined as the target face feature, or the cosine or sine of the ++abc is determined as the target face feature, or the angle corresponding to the ++abc is directly determined as the target face feature.

In another possible implementation manner, in the case that the face shape parameter includes a chin angle parameter, the viewer terminal determines a third line segment corresponding to the first chin key point and the second chin key point, and a fourth line segment corresponding to the second chin key point according to the position of the first chin key point, the position of the second chin key point, and the position of the third chin key point, and determines the chin angle parameter according to an included angle between the third line segment and the fourth line segment. The first chin key point and the second chin key point are located at the same height, the third chin key point is a vertex in the plurality of chin key points, namely the third chin key point is a key point located at the lowest position in the plurality of chin key points. For example, referring to fig. 10, the first chin key point is F, the second chin key point is G, the third chin key point is C, the third line segment is FG, and the fourth line segment is CG, r6=tan=fgc, the tangent r6 of ++fgc is determined as the target face feature, or the cosine or sine of ++fgc is determined as the target face feature, or the angle corresponding to ++fgc is directly determined as the target face feature.

It should be noted that the target face features of the target face area determined by the viewer terminal include one or more of the above-mentioned target face features. For example, the target face features are r1, or the target face features are r1 and r2, or the target face features are r3, r4, r5, and r6.

In the above embodiment, the audience terminal is only used to identify the live broadcast picture and acquire the target face feature as an example, in another embodiment, the audience terminal transmits the live broadcast picture when the user performs the triggering operation to the live broadcast server, the live broadcast server identifies the live broadcast picture, acquires the target face feature corresponding to the target face region, and then transmits the acquired target face feature to the audience terminal.

403. The viewer terminal transmits a virtual gift-gifting request to the live server in response to the virtual gift-gifting operation.

The virtual gift giving request carries the target face characteristics, so that the terminal in the subsequent living broadcast room displays the virtual gift special effect corresponding to the virtual gift in the target face area according to the target face characteristics. Optionally, the virtual gift-gifting request carries virtual gift information to enable the subsequent anchor terminal to determine which virtual gift is gifted. Optionally, the virtual gift-gifting request carries the number of virtual gifts, so that the subsequent anchor terminal can determine the number of virtual gifts gifted.

In one possible implementation, the audience terminal displays a virtual gift presentation interface at an upper layer of the live interface; or switching from the live broadcast interface to the virtual gift giving interface; and responding to the selection operation of any virtual gift in the virtual gift presentation interface, and initiating a virtual gift presentation request. For example, the gift-giving interface is a floating window popped up at an upper layer of the live interface, or the gift-giving interface is a new interface different from the live interface, or the virtual gift interface is another interface, which is not limited in the present application.

In one possible implementation, the virtual gift gifting interface includes special effect thumbnails corresponding to a plurality of virtual gifts, and the audience terminal initiates the virtual gift gifting request in response to a selection operation of the special effect thumbnail corresponding to any one of the virtual gifts. The special effect thumbnail is a thumbnail of a special effect of the virtual gift corresponding to the virtual gift, and the special effect thumbnail is selected, namely, the corresponding virtual gift is selected. Optionally, the virtual gift effect is a dynamic image and the effect thumbnail is a static image.

In addition, the virtual gift effect is a text, graphic, or other form of effect.

In one possible implementation, the virtual gift gifting interface includes a gifting control, and the viewer terminal sets the selected virtual gift to a selected state in response to a selection operation of any one of the virtual gifts; and responding to the triggering operation of the gift control, and initiating a gift request of the virtual gift in the selected state. The virtual gift in the selected state is the virtual gift to be presented. Alternatively, if the virtual gift presentation interface displays special effect thumbnails corresponding to the virtual gift, the viewer terminal sets the selected special effect thumbnail to a selected state in response to a selection operation of any special effect thumbnail.

In one possible implementation, the gift information is carried in the virtual gift-giving request, and the live server issues the virtual gift to the anchor terminal.

406. The anchor terminal determines a plurality of face areas included in a live interface of the live broadcasting room.

Since the current live view of the anchor terminal may be changed compared with the live view of the viewer terminal when the trigger operation is performed, it is necessary to determine a plurality of face areas in the current live view interface of the anchor terminal.

In one possible implementation, the anchor terminal performs face recognition on the live broadcast picture to determine a plurality of face areas. The embodiment of determining the plurality of face areas by face recognition is similar to the embodiment of determining the face areas by the viewer terminal in step 402, and will not be described herein.

407. The anchor terminal determines the face features matched with the target face features in the face features corresponding to the plurality of face regions, and determines the face region corresponding to the face features matched with the target face features as the target face region.

The matching of the face features and the target face features is to determine the face features with the highest similarity to the target face features in the face features, and the face region corresponding to the face features with the highest similarity is determined as the target face region, and the anchor corresponding to the target face region is considered to be the anchor presented with the virtual gift.

In one possible implementation manner, difference values between face features of a plurality of face regions and target face features are obtained respectively, so that a plurality of difference values are obtained, and a face region corresponding to a minimum difference value in the plurality of difference values is determined as the target face region. Wherein the variance value includes a difference value, a square difference value, a standard deviation, or other numerical value representing the variance. For example, if the target face features are r1 and r2, any of the face features is r1' and r2', the difference value is (r 1-r1 ') ² +(r2-r2′) ² Or the difference value is (r 1-r1 ') + (r 2-r 2').

In one possible implementation manner, the virtual gift giving request carries the number of virtual gift, and after receiving the virtual gift giving request, the anchor terminal obtains the number of virtual gift and displays the special effect of the virtual gift according to the number of virtual gift.

Optionally, the anchor terminal superimposes and displays the virtual gift effects of the number in the target face area in response to the number of the virtual gift being greater than the first reference number and less than the second reference number, wherein the first reference number is less than the second reference number. For example, if the first reference number is 1, the second reference number is 10, the virtual gift to be presented is "ear", and the number carried in the virtual gift presentation request is 5, then 5 pairs of "ears" can be superimposed, and the superimposed "ears" can be displayed. For another example, the virtual gift effect corresponding to the virtual gift is "fat", and the target face is increased by 10% on the original basis when one virtual gift is received, and by 50% on the original basis when 5 virtual gifts are received.

Optionally, the anchor terminal displays the special effect of the virtual gift and text information corresponding to the virtual gift in the target face area in response to the number of the virtual gift being greater than the third reference number. The text information comprises the number of virtual gifts, and the third reference number is not smaller than the second reference number. For example, the third reference number is 10, the number carried in the virtual gift presentation request is 20, the presented virtual gift is "yacht", the "yacht" special effect is displayed, and "20×" is displayed above the "yacht" special effect or other surrounding area, indicating that 20 "yachts are presented.

In one possible implementation, a virtual gift effect is displayed at a target location in a target face region. Wherein the target part is the part of eyes, face, forehead, etc.

In one possible implementation, the virtual gift effect is provided with a corresponding display duration, and the virtual gift effect is not displayed when the display duration is reached.

In another embodiment, the plurality of audience terminals in the living room can each send the virtual gift-gifting request to the anchor terminal in the above manner, and if the plurality of audience terminals send the virtual gift-gifting request to the anchor terminal at the same time, the anchor terminal displays the corresponding special effects of the patrol gift according to the plurality of virtual gift-gifting requests. Optionally, if the plurality of audience terminals give the same virtual gift to the anchor terminal, the anchor terminal displays according to the number of the virtual gift and the display mode of the special effect of the virtual gift; if a plurality of audience terminals give different virtual gifts to the anchor terminal, the anchor terminal displays the virtual gift special effects corresponding to each virtual gift respectively, and the virtual gift special effects corresponding to the different virtual gifts can be displayed simultaneously or sequentially according to a preset display sequence.

409. And the anchor terminal sends the live broadcast picture added with the virtual gift special effect to a live broadcast server.

410. The live broadcast server issues live broadcast pictures in a live broadcast room.

And when the face features are acquired, the corresponding ratio of the distances between different face key points is determined as the face features, or the face features are determined according to the angles formed by the different face key points, so that the corresponding face regions can be accurately represented, and the accuracy of the face features is improved. And when the accurate target face features are adopted and the corresponding target face areas are matched, the determined target face areas can be ensured to be the face areas where the user wants to give the virtual gift.
