step 103: and filling the target area with the hair textures if the density of the hair textures in the target area does not meet the first preset density threshold corresponding to the target area, so that the density of the hair textures in the filled target area meets the first preset density threshold.
In the embodiment of the invention, the area of the target object is determined from the target image; and filling the hair textures in the target area if the density of the hair textures in the target area does not meet the first preset density threshold corresponding to the target area in the target area, so that the density of the hair textures in the filled target area meets the first preset density threshold, and further, corresponding hair filling aiming at the requirements of users 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 shoots by using the electronic equipment, the effect of the filled target object can be previewed on the preview interface, so that the interestingness of the user can be increased, and when the user is satisfied with the filling effect, the user can click to shoot, shoot and image the effect image of the filled target object, and the interactivity of the user and the electronic equipment is enhanced.
In one example, when the target image is an image photograph of the target object, the acquiring 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 art, for a target object in an image, a user is required 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 user experience is reduced.
In some embodiments of the present invention, the target object described in step 102 comprises an eyebrow or a eyelash.
In one example, determining the region of the target object from the target image as described in step 102 includes:
acquiring a plurality of contour feature points of a target object from a target image;
and determining the outline of the target object according to the outline characteristic points, wherein the range of the outline girth is the area of the target object.
In fig. 2, the plurality of contour feature points are "o", and the range surrounded by the plurality of "o" is an area of the eyebrow.
In one example, the plurality of contour feature points may include: eyebrow, belly, waist, peak, slope, tail and apex.
In fig. 3, the plurality of contour feature points are "o", and the range surrounded by the plurality of "o" is the region of the eyelash object.
In the embodiment of the invention, the area of the eyebrow or the eyelash in the target image can be determined from the plurality of contour feature points of the eyebrow or the eyelash, and the area to be filled can be determined, so that the operation is convenient and quick.
For convenience of description, an eyebrow is described 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 trend.
For example, in fig. 2, the target object has 3 regions.
It should be noted that, the area of the corresponding number of target objects may be selected according to the beautification precision, which is not described herein.
In one example, the density of the hair texture is the sparseness of the eyebrow distribution, and if the density of the hair texture in the target area does not meet the first preset density threshold corresponding to the target area for the target area in the area of the target object in step 103, filling the hair texture in the target area so that the density of the hair texture in the filled target area meets the first preset density threshold includes:
when the sparse program of the distribution of the hairs in the target area does not meet the corresponding first preset density threshold, the target area needs to be filled with the hairs so that the distribution sparsity of the eyebrows in the target area is changed from sparse to dense, and the distribution sparsity 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 sparseness of the whole eyebrows of the user, so that the filled eyebrows are more uniform, and the filled eyebrows become abrupt due to too much hair texture in a certain area, so that the overall aesthetic feeling of the target object is increased, and the user experience is improved.
In one example, in addition to the distribution sparseness, the eyebrow may further relate to brightness information, that is, the overall color shade of the eyebrow, and if the density of the hair texture in the target area does not meet the first preset density 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 meets the first preset density threshold in the target area, which includes:
and filling the hair texture in the target 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 and the brightness information of the hair texture in the target area does not meet the preset brightness threshold corresponding to the target area, so that the density of the hair texture in the filled target area meets the first preset density threshold and the brightness information of the hair texture in the filled target area meets the preset brightness threshold.
Taking black dense eyebrows as an example, in a target area (can be any area in fig. 2) of the eyebrows, the sparseness of the distribution of the hair in the target area is sparse, and the color shade is shallow, then the hair textures need to be filled in the area so that the sparseness of the distribution of the eyebrows in the target area is changed from sparse to dense, and the color shade is shallow to deep, so that the sparseness of the distribution of the eyebrows in the filled target area meets a corresponding first preset density threshold value, and the darkness of the eyebrows in the filled target area meets a preset brightness threshold value.
It should be noted that, the preset brightness threshold value can be determined according to the color shade degree of the whole eyebrow of the user, so that the color shade degree of the filled eyebrow is more uniform, the filled eyebrow becomes abrupt due to the fact that a certain area is not filled with the deep eyebrow, the whole aesthetic feeling of the target object is increased, and the user experience is improved.
In addition, when the color shade of the eyebrow of the target area is inconsistent with that of other areas, for example, when the color shade of the eyebrow of the target area is smaller than that of other areas, the color shade of the eyebrow of the target area can be adjusted first, so that the color shade of the eyebrow of the target area is consistent with that of the other areas as much as possible, and is further uniform as a whole, and the preference of a user is met; after the color depth degree of the target area is adjusted, the area is filled with hair, so that the filled eyebrows are free from uneven distribution and inconsistent color depth, the whole eyebrow effect is attractive, the preference of a user is met, and the user experience degree is improved.
In one example, if there is a missing region within the target region, then the missing portion needs to be filled based on standard target objects, specifically including:
when the density of the hair textures in the target area does not meet a second preset density threshold value, determining that a missing area exists in the target area; wherein the second preset density threshold is less than the first preset density threshold;
filling a hair texture in a target area, 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 refers to 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 after filling according to the whole eyebrow sparse program and the color shade degree of the user, that is, before filling the user's eyebrow, a standard eyebrow may be first determined based on the whole eyebrow sparse program and the color shade degree of the user's eyebrow, so that the eyebrow with a missing area may be filled correspondingly, so that after the eyebrow with a missing area is filled by the standard eyebrow, the effect is uniform from the sparse degree on the adult, the color degree is suitable, the filling effect of the missing area is not inconsistent with other areas of the eyebrow, but the whole is abrupt, and the effect is relatively poor.
In fig. 4, there is a missing region 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 a small difference in the minimum length of the missing region from 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 area, a part of hair can be cut from the target area to be filled, so that the filled eyebrows are more consistent with the eyebrow characteristics of the user, namely the effect of each user after filling is not the same, the method has the characteristics of the user, and the user experience is higher.
In an embodiment of the present invention, optionally, filling the target area with the hair texture 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 according to the size information of the first hair and the second hair, and determining the same-side longest distance between the first endpoint of the first hair and the second hair;
and filling the hair textures in the target area according to the first hair and the second hair when the shortest distance is smaller than a first preset distance threshold value and the same-side longest distance is larger than a second preset distance threshold value.
Therefore, the judging condition of whether the hair is filled or not can be determined according to the distance between the hair filling judging condition and the hair filling judging condition, so that the hair filling judging device enables the hair to be more natural and attractive and meets the requirements of users.
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 acquired; next, determining the shortest distance (i.e., the minimum right angle distance) between the first end point D of the first hair A1 and the second hair, and determining the ipsilateral distance (the first ipsilateral distance and the second ipsilateral distance, which may be the same or different, taking the longest ipsilateral distance as an example) between the first end point D of the first hair A1 and the first end point of the second hair A2; and filling the hair textures in the target area according to the first hair and the second hair when the shortest distance is smaller than a first preset distance threshold value and the same-side long distance of the end points is larger than a second preset distance threshold value.
In one example, filling hair textures within a target region from a first hair and a second hair comprises:
the first hair and/or the second hair is added within the target area.
In the embodiment of the invention, the nearest hair in the area to be filled is preferably used for filling, so that the filling effect is best, the integral aesthetic feeling of eyebrows is improved, and the user experience is better.
In one example, adding the first hair and/or the second hair within the target area includes:
the first hair and the second hair are respectively the side lengths of the quadrangle, and a third eyebrow is added on a connecting line of the 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 sides of the quadrangle, the growing trend of the connecting line with the e and the f is filled in the connecting line of the middle point of the e and the f sides of the quadrangle, the growing trend of the connecting line with the e and the f is determined in the target area after the connecting line of the middle point of the e and the f sides is determined, the growing trend of the connecting line with the e and the f is determined in the target area, and then the filling is carried out according to the third hair, so that the filled effect is more consistent with the growing area of the eyebrows in the target area, and the overall aesthetic feeling of the eyebrows is increased.
In one example, the size information of the first hair includes a diameter of the first hair and the size information of the second hair includes a diameter of the second hair;
before filling the hair texture in the target area from the first hair and the second hair, the method further comprises, before the image processing method further comprises:
a first preset distance threshold is determined based on the diameter of the first hair and the diameter of the second hair, and a second preset distance threshold is determined.
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 before, or performed after, which will not be described herein.
In one example, the first preset distance threshold is: k1 (b1+b2)/k 2; the second preset distance threshold is: (b1+b2)/k2×k1;
wherein b1 is the diameter of the first hair, b2 is the diameter of the second hair, k1 and k2 are positive numbers, k1> k2.
