In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects may be practiced without these specific details.
The embodiment of the disclosure provides a picture processing method. The image processing method provided by the embodiment can be executed by a computing device, the computing device can be implemented as software, or implemented as a combination of software and hardware, and the computing device can be integrally arranged in a server, a terminal device and the like.
Referring to fig. 1, an image processing method provided in the embodiment of the present disclosure includes:
s101, identifying a head region and a body region of a human body in a picture to be processed, wherein the body region is a region of the human body except the head region;
the method provided by the embodiment is mainly applied to a process of performing child body beautification on a human body in a picture in terminal beauty application, so that the human body in the picture can present a special effect which looks like a child. As shown in fig. 2, the human body in the picture is a normal adult body type, and after the child body beautification treatment is performed on the human body in the picture, as shown in fig. 3, the human body in the picture is a child body type.
Considering that the body size of a child is large in head and a body part appears short compared to the body size of an adult, the treatment can be performed separately for the head area and the body area of a human body. In specific implementation, the head region and the body region of the human body in the picture to be processed need to be identified first, where the body region may include other parts of the human body, such as the neck, the trunk, and the limbs, except the head.
When the picture is processed, the terminal identifies pixel points corresponding to the human body in the picture according to an algorithm, and determines key points of main parts, such as shoulder key points, eye key points, nose key points, hip key points and the like, so as to determine the head area and the body area of the human body in the picture.
S102, amplifying the head area of the human body in the picture;
after the head region and the body region of the human body are determined according to the above steps, the head region and the body region can be processed respectively. Considering that the head region has a small change in area and the body region has a large change in area, in order to ensure a good reference contrast effect, the head region is processed first, that is, the head region of the human body in the picture is amplified.
The display effect of the body shape of the child is that the head is larger, the trunk is smaller, and when the child body beautification treatment is carried out, the head area of the human body in the picture needs to be amplified. The amplification treatment can be diffusion from the middle part to the periphery, and the effect of uniform amplification is displayed.
And S103, taking the lower boundary line of the head region after the enlargement processing as the upper boundary line of the body region, and carrying out reduction processing on the body region.
The body area of the adult body type is larger than that of the child, when the child body beautifying treatment is carried out, the body area of the human body needs to be reduced, the reduction can be carried out by reducing the upper body and the lower body of the human body in the same proportion, and the horizontal and vertical reduction proportion can be adjusted adaptively, so that the whole body is more uniform.
In order to ensure the connectivity of the head area and the body area of the human body, after the head area is amplified, the lower boundary line of the head area after the amplification is used as the upper boundary line when the body area is processed, namely, the body area is contracted and closed from the foot area to the upper boundary line, so that the technical problem of body beautifying processing distortion caused by the separation of the head area and the body area in the childhood processing process is solved.
Furthermore, after the step of subjecting the body region to a reduction process, the method may further comprise at least one of:
carrying out amplification processing on an eye region of the head region;
adding a blush image layer in the face area of the head area;
performing retraction treatment on a chin region of the head region;
and performing skin tendering and body beautifying treatment on the head area.
And S104, performing skin tendering and body beautifying treatment on the head region subjected to the amplification treatment.
In the process of child body shaping, in addition to the enlargement processing of the head region and the reduction processing of the body region in the above-mentioned process, in order to achieve a more realistic child body shaping effect, it is necessary to perform specific body shaping processing on the head region after the enlargement processing, for example, to perform skin tendering processing on the head region of the human body, so that the head region, especially the face region, exhibits special effects similar to children, such as large eyes, face blush, and small chin, so that the whole human body is closer to the children, and the childhood effect is more realistic.
In the skin tendering and body beautifying treatment process, the eye region in the head region can be obtained according to a conventional human eye recognition mode, and the center of the eye region is taken as a reference point to be uniformly expanded outwards. The adding of the blush layer to the face area is a special effect of adding the blush layer to the face of the human body, and the chin retraction treatment is an effect of recovering the chin in the human body and is not described in detail.
In the method for treating the skin beautification of the human body in the picture by children provided by the embodiment of the invention, the pixels in the head area are stretched outwards from the central point, so that the effect of big head is obtained. Meanwhile, the area below the head is stretched upwards, namely the upper half body and the legs are shortened, so that the effect of reducing the body is achieved. In addition, the image buffing and other treatments are combined to buff the face area, so that the face area looks smooth, people look younger, and the effect of low age is achieved.
According to a specific implementation manner of the embodiment of the present disclosure, the step of identifying the human body region in the picture is further defined. As shown in fig. 4, the step of identifying the head region and the body region of the human body in the picture to be processed may include:
s401, according to key points of the human body in the picture, framing a complete region of the human body;
when the picture is processed, the key points of the human body, including shoulder key points, hip key points, foot key points, leg key points, eye key points, nose key points, ear key points and the like, can be obtained firstly according to a preset human body recognition algorithm.
S402, determining the head central point of the human body and the height and width of the head area;
according to the key points of the human body, the key points of the head of the human body and the height and the width of the head area of the human body can be determined firstly.
S403, determining a head region of the human body in the full region according to the head center point and the height and width of the head region;
the head area is an approximate ellipse or a prototype area, and after the head central point of the human body area is determined, the height and the width of the determined head area are combined, so that the head area of the human body can be determined.
S404, regarding an area other than the head area in the complete area as a body area of the human body.
The above-mentioned complete region of the human body and the head region of the human body are determined, the region of the complete region except the head region can be used as the body region of the human body, and then the head region of the human body is enlarged and the body region is reduced.
According to a specific implementation manner of the embodiment of the present disclosure, as shown in fig. 5, the step of determining the head center point of the human body and the height and width of the head region may include:
s501, determining a head central point of the human body according to a target key point of the human body, which is associated with the head;
when determining the head region, the head center point of the head region needs to be determined first. Specifically, the head center point of the human body is determined according to the target key points of the human body, which are associated with the head.
Optionally, the step of determining the head center point of the human body according to the target key point of the human body associated with the head includes:
identifying eye, nose and ear key points of the human body;
connecting the eye key points, the nose key points and the ear key points to draw key point region graphs;
and determining the geometric center of the key point region graph as the head center point of the human body.
The target key points of the human body, which are associated with the head, are key points with eyes, nose and ears, and according to the positions of the key points, the head central point can be obtained through the operation of taking the central point.
S502, determining the size of a reference central line of the human body in the picture;
considering that the distance of the human body from the screen in the picture affects the size of the head region of the human body, the size of the head region of the human body from the reference center line of the screen is determined before the head region of the human body is determined. In specific implementation, the size of the reference midline can be determined according to the shoulder key points, the hip key points and the like of the human body.
Specifically, the step of determining the size of the reference centerline of the human body in the picture includes:
determining a shoulder midpoint between two shoulder key points of the human body and a hip midpoint between two hip key points;
determining a reference midline between a shoulder midpoint and a hip midpoint of the human body;
measuring a dimension of a reference midline of the human body.
S503, determining the height and the width of the head area according to the size of the reference middle line.
After the size of the reference centerline of the human body in the picture is determined, the width and height of the head region can be determined. For example, the step of determining the height and width of the head region based on the dimensions of the reference midline comprises:
multiplying the size of the reference midline of the human body by a first scaling factor to obtain the width of the head region, and multiplying the size of the reference midline of the human body by a second scaling factor to obtain the height of the head region.
The following is defined for a specific process. According to a specific implementation manner of the embodiment of the present disclosure, the step of performing an enlargement process on the head region of the human body in the picture may include:
determining a first direction and a second direction of the head region, wherein the first direction is a direction parallel to a lower boundary line of the head region, and the second direction is a direction perpendicular to the lower boundary line of the head region;
stretching the head region towards two ends along the first direction at the head center point of the head region;
and stretching the head area towards two ends along the second direction at the head central point of the head area.
In this embodiment, when the head region is enlarged, not only the first direction, i.e. the horizontal direction shown in the figure, but also the second direction, i.e. the numerical direction, of the head region is also outwardly extended, and of course, the two mutually perpendicular directions with a transverse included angle of 45 ° may also be extended, so that the head region of the human body is uniformly enlarged outward in a spherical shape, and the head is uniformly enlarged.
According to another specific implementation manner of the embodiment of the present disclosure, the step of performing a reduction process on the body region by using the lower boundary line of the head region after the enlargement process as the upper boundary line of the body region includes:
determining the lower boundary line of the head region after the amplification treatment as the upper boundary line of the body region stretching, and determining the foot region of the body region as a stretching starting point;
stretching the body region from the stretch starting point toward the upper boundary line such that the body region is scaled down in the first direction and the second direction.
In the present embodiment, when the reduction processing is performed on the body region, the lower end of the head region is used as a boundary line in the upward stretching, and the regions below this boundary line are all stretched upward, and the stretching is reduced in an equal proportion, and the position where the stretching is completed is the foot region. In this way, the body region stretches more evenly, realistically simulating the inverse process of a human body growing from a child to an adult.
According to a specific implementation manner of the embodiment of the present disclosure, as shown in fig. 6, before the step of performing the enlargement processing on the head region of the human body in the picture, the method may further include:
s601, receiving body beauty request information;
in this embodiment, it is considered that the children beauty requirements of different users are different, for example, the children beauty degree of the requirement is the beauty degree of a two-year-old child or the beauty degree of a seven-eight-year-old child, and the beauty parameters corresponding to different children beauty requirements are different.
In order to provide different user-specific beauty requirements, the terminal may receive user's beauty request information, for example, the user inputs beauty request information through a stretch bar control, an input interface, and the like. The body beautifying request information may be, but is not limited to, the age of the child corresponding to the requested child body beautifying treatment, or the body length of the child requested to be treated by the child body beautifying treatment.
S602, determining a requested target beauty position according to the beauty request information;
different body beautifying gears are preset in the terminal, and the body beautifying effect is different due to different body beautifying parameters corresponding to each body beautifying gear. For example, the larger the beauty shift position is, the higher the child beautification degree is, and the smaller the age of the treated simulated child is, whereas the smaller the beauty shift position is, the lower the child beautification degree is, and the larger the age of the treated simulated child is.
After receiving the beauty request information input by the user, the terminal can determine the requested target beauty gear according to the beauty request information.
The step of amplifying the head region of the human body in the picture comprises the following steps:
s603, carrying out amplification processing corresponding to the target beauty body gear on the head area of the human body in the picture;
after determining the corresponding target beauty grade according to the above steps, the enlargement processing of the head region may be performed in combination with the target beauty grade. For example, if the target beauty level is larger, the enlargement factor of the head region is larger.
The step of performing a reduction process on the body region includes:
s604, carrying out reduction processing corresponding to the target beauty body position on the body area.
Correspondingly, after the target beauty grade is determined, corresponding reduction processing needs to be carried out in combination with the target beauty grade. For example, as the target beauty level decreases, the reduction coefficient of the body region increases, and the corresponding reduced size decreases.
In addition, the terminal can not only specifically control the child body shaping degree according to the user request, but also limit the limit value of the child body shaping grade, namely, an upper limit maximum value is preset, so that excessive distortion of the effect is avoided. Of course, the maximum value is adjusted according to the actual situation, for example, if an exaggerated special effect is required in the actual situation, the maximum value is larger, and if we want to pursue the nature, the maximum value is smaller without being exaggerated too much.
Corresponding to the above method embodiment, referring to fig. 7, an embodiment of the present disclosure further provides a picture processing apparatus 70, including:
