Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of an image processing method according to an embodiment of the present invention. As shown in fig. 1, the image processing method includes:
step 101: acquiring a target image;
step 102: determining a region of a target object from the target image;
step 103: and for a target area in the area of the target object, filling hair textures in the target area under the condition that the density of the hair textures in the target area does not meet a first preset density threshold corresponding to the target area, so that the density of the hair textures in the target area after filling meets the first preset density threshold.
In the embodiment of the invention, the area of the target object is determined from the target image; in the target area in the target object area, if the density of the hair texture in the target area does not meet the first preset density threshold corresponding to the target area, the hair texture is filled in the target area, so that the density of the hair texture in the filled target area meets the first preset density threshold, and then the hair filling corresponding to the requirements of the user can be realized, and the user experience is improved.
In an embodiment of the invention, the target image is an image comprising a preview of the target object or an image photograph of the target object.
In one example, when the target image is an image previewed by the electronic device, the acquiring the target image in step 101 includes:
and acquiring a preview image of the target object through a camera of the electronic equipment.
In the embodiment of the invention, when the user uses the electronic equipment to shoot, the effect of the target object after filling can be previewed on the preview interface, so that the interestingness of the user can be increased, when the user is satisfied with the filling effect, the user can click to shoot, the effect image of the target object after filling is shot and imaged, and the interactivity between the user and the electronic equipment is enhanced.
In one example, when the target image is an image photo of the target object, the acquiring of the target object in step 101 includes:
receiving a selection operation of a user on a plurality of images stored in the electronic equipment;
in response to the selection operation, a target image is acquired.
In the related technology, for a target object in an image, a user needs to manually adjust a filling effect, and the manual filling effect is related to the manual capability of the user, so that the filling effect of the target object does not necessarily accord with the preference of the user, and further the user experience is reduced.
In some embodiments of the present invention, the target object of step 102 comprises an eyebrow or an eyelash.
In one example, the determining the region of the target object from the target image in step 102 includes:
acquiring a plurality of contour feature points of a target object from a target image;
and determining the contour of the target object according to the plurality of contour feature points, wherein the range of the contour enclosing city is the region of the target object.
In fig. 2, the plurality of contour feature points are "○", and the range surrounded by the plurality of "○" is an area of the eyebrow.
In one example, the plurality of contour feature points may include: eyebrow, eyebrow belly, eyebrow waist, eyebrow peak, eyebrow slope, eyebrow tail, and eyebrow tip.
In fig. 3, the plurality of contour feature points are "○", and the range surrounded by the plurality of "○" is the region of the eyelash object.
In the embodiment of the invention, the area of the eyebrows or eyelashes in the target image can be determined according to the plurality of contour characteristic points of the eyebrows or eyelashes, and the area needing to be filled can be determined, so that the operation is convenient and quick.
For convenience of description, the eyebrow will be explained as an example hereinafter.
In one example, the region of the target object includes a plurality of regions, and the region of the target object is a region divided according to a hair texture growth tendency.
For example, in fig. 2, the number of regions of the target object is 3.
It should be noted that, the areas of the corresponding number of target objects may be selected according to the beautification precision, which is not described herein again.
In an example, the filling of the hair texture in the target region in step 103, if the density of the hair texture in the target region does not satisfy the first preset density threshold corresponding to the target region, so that the density of the hair texture in the filled target region satisfies the first preset density threshold, includes:
when the hair distribution sparseness program in the target area does not meet the corresponding first preset density threshold, the hair texture needs to be filled in the target area, so that the distribution sparseness of the eyebrows in the target area is changed from sparse to dense, and the distribution sparseness of the eyebrows in the filled target area meets the corresponding first preset density threshold.
It should be noted that the first preset density threshold may be determined according to the distribution sparsity of the whole eyebrows of the user, so that the filled eyebrows are more uniform, and the filled eyebrows are not abrupt due to filling of too many hair textures in a certain area, thereby increasing the whole aesthetic feeling of the target object and improving the user experience.
In one example, the eyebrow may relate to brightness information, that is, the color depth of the whole eyebrow, in addition to the distribution sparseness, and the filling of the hair texture in the target region in step 103, if the density of the hair texture in the target region does not satisfy the first preset density threshold corresponding to the target region, so that the density of the hair texture in the filled target region satisfies the first preset density threshold, includes:
for a target area in the area of the target object, if the density of the hair texture in the target area does not satisfy a first preset density threshold corresponding to the target area and the brightness information of the hair texture in the target area does not satisfy a preset brightness threshold corresponding to the target area, filling the hair texture in the target area so that the density of the hair texture in the filled target area satisfies the first preset density threshold and the brightness information of the hair texture in the filled target area satisfies the preset brightness threshold.
Taking black dense eyebrows as an example, in a target area (which may be any area in fig. 2) of the eyebrows, if the distribution sparsity of the hairs in the target area is sparse and the color depth is light, hair textures need to be filled in the area, so that the distribution sparsity of the eyebrows in the target area is changed from sparse to dense, and the color depth is changed from shallow to deep, so that the distribution sparsity of the eyebrows in the filled target area meets a corresponding first preset density threshold, and the depth of the eyebrows in the filled target area meets a preset brightness threshold.
It should be noted that the preset brightness threshold may be determined according to the color depth of the whole eyebrow of the user, so that the color depth of the filled eyebrow is more uniform, and there is no situation that the filled eyebrow becomes too steep due to filling of a deeper eyebrow in a certain area, thereby increasing the whole aesthetic feeling of the target object and improving the user experience.
In addition, when the color depth of the eyebrows in the target area is inconsistent with the color depth of other areas, for example, when the color depth of the eyebrows in the target area is smaller than the color depth of other areas, the color depth of the eyebrows in the target area can be adjusted first, so that the color depth of the eyebrows in the target area is consistent with the color depth of other areas as much as possible, and the whole is relatively uniform, and accords with the preference of a user; after the color depth degree of the target area is adjusted, hair filling is carried out on the area, so that the filled eyebrows are free from the conditions of uneven distribution and inconsistent color depth, the overall effect of the eyebrows is attractive, the preference of a user is met, and the user experience is improved.
In one example, if there is a missing region in the target region, the missing part needs to be filled based on the standard target object, which specifically includes:
when the density of the hair texture in the target area does not meet a second preset density threshold, determining that a missing area exists in the target area; wherein the second preset density threshold is smaller than the first preset density threshold;
filling a hair texture within a target region, comprising:
filling the missing region according to the hair texture in the region corresponding to the missing region in the standard target object; the standard target object is a target object in which the density of the hair texture in each target area meets a first preset density threshold corresponding to each target area, and the brightness information of the hair texture in each target area meets a preset brightness threshold corresponding to each target area.
It should be noted that the standard target object may be an eyebrow that is filled according to the sparse program and the color depth of the entire eyebrow of the user, that is, before the eyebrow of the user is filled, a standard eyebrow may be determined based on the entire sparse program and the color depth of the eyebrow of the user, so that the eyebrow with the missing region may be filled correspondingly, and after the eyebrow with the missing region is filled through the standard eyebrow, the effect is uniform in sparse degree from the adult, the color depth is appropriate, the filling effect of the missing region is not inconsistent with other regions of the eyebrow, and the entire eyebrow is more obtrusive and the effect is worse.
In fig. 4, a missing region exists between the contour feature point 1 and the contour feature point 2 (the missing region may also be filled by a region corresponding to the missing region between the contour feature point 1 and the contour feature point 2 in the standard target object according to the fact that the minimum length of the missing region is smaller than the length between the contour feature point 1 and the contour feature point 2, for example, the minimum length of the missing region is 1/3 of the length between the contour feature point 1 and the contour feature point 2).
For filling of the missing region, a part of hair can be cut from the target region for filling, so that the filled eyebrow can better accord with the eyebrow characteristics of the user, namely the filled eyebrow has different effects, the filling method has the personal characteristics of the user, and the user experience is higher.
In this embodiment of the present invention, optionally, the filling the hair texture in the target region in step 103 includes:
acquiring size information of a first hair and a second hair in a target area;
determining the shortest distance between the first hair and the second hair and the longest distance between the first end point of the first hair and the same side of the second hair according to the size information of the first hair and the second hair;
and under the condition that the shortest distance is smaller than a first preset distance threshold value and the longest distance on the same side is larger than a second preset distance threshold value, filling hair textures in the target area according to the first hair and the second hair.
Therefore, the judgment condition of whether to fill the hair can be determined according to the distance between the two, so that the hair filling is more natural and beautiful, and the requirements of users are met.
In fig. 5, size information of a first hair a1 and a second hair a2 within a second target area (from left to right) is obtained; next, the shortest distance (i.e., the smallest right-angle distance) between the first end point D of the first hair a1 and the second hair a is determined, and the ipsilateral distance (the first ipsilateral distance and the second ipsilateral distance, which may be the same or different, for example, the longest ipsilateral distance) between the first end point D of the first hair a1 and the first end point of the second hair a2 is determined; and when the shortest distance is smaller than a first preset distance threshold value and the longest distance on the same side of the end point is larger than a second preset distance threshold value, filling hair textures in the target area according to the first hair and the second hair.
In one example, filling a hair texture within a target region according to a first hair and a second hair, comprises:
a first hair and/or a second hair is added to the target area.
In the embodiment of the invention, the hair closest to the area to be filled is preferably taken into consideration for filling, so that the filling effect is best, the integral aesthetic feeling of eyebrow is improved, and the user experience is better.
In one example, adding a first hair and/or a second hair within a target area includes:
respectively taking the first hair and the second hair as the side lengths of the quadrangle, and adding a third eyebrow on a connecting line of midpoints of the other two side lengths in the quadrangle; wherein the third eyebrow is the eyebrow in the target area.
In fig. 6, the first hair a1 and the second hair a2 are respectively the side length of the quadrangle, the growth trend of the connecting line between the e and f is filled on the connecting line of the middle points of the e and f side lengths of the quadrangle, the third eyebrow with the same length is filled, namely after the connecting line of the middle points of the e and f side lengths is determined, the growth trend of the connecting line between the e and f and the third eyebrow with the same length are determined from the target area, and then the filling is performed according to the third hair, so that the filled effect is more in line with the growth area of the eyebrow in the target area, and the integral aesthetic feeling of the eyebrow is increased.
In one example, the size information of the first hair comprises a diameter of the first hair, and the size information of the second hair comprises a diameter of the second hair;
before filling the hair texture in the target region according to the first hair and the second hair, the method further comprises:
determining a first preset distance threshold value and a second preset distance threshold value according to the diameter of the first hair and the diameter of the second hair.
It should be noted that the step of determining the first preset distance threshold and the second preset distance threshold may be performed simultaneously with the step of determining the shortest distance and the longest distance on the same side, or performed first, or performed later, and will not be described herein again.
In one example, the first preset distance threshold is: k1 (b1+ b2)/k 2; the second preset distance threshold is: (b1+ b2)/k2 × k 1;
wherein b1 is the diameter of the first hair, b2 is the diameter of the second hair, k1 and k2 are positive numbers, and k1> k 2.
