Detailed Description
The technical scheme of the application is further elaborated below with reference to the drawings in the specification and the specific embodiments.
As shown in fig. 1, the present embodiment provides an image processing method, including:
step S110: according to the deformation proportion of a first part of a target object in an image in a first direction, carrying out deformation processing on the first part in a second direction; wherein the second direction is perpendicular to the first direction.
The image processing method provided in the present embodiment may be a method applied to an image apparatus. The image device may be various types of electronic devices; such as a stationary device or a mobile device. The fixture may include: desktop computers or servers, etc. The mobile device may include: an in-vehicle apparatus, a person-vehicle apparatus, a robot, or the like. The manned device may include: a cell phone, a tablet computer, or a wearable device, etc.
The image may be: an image to be processed; for example, an original image acquired by a camera; or images to be deformed received from other electronic devices.
The target object may be an image of various acquisition objects; the acquisition object may include: humans, animals, scenery, or vehicles, among others.
For illustration, the target object may be a portrait. The first portion may be an image of a portion of a person in the image. For example, the figures may include: imaging of several parts of the head, neck, shoulders, chest, waist, abdomen, crotch, legs, hands, etc.; the first part may include: the head forms the head portrait. The target object may further include, in addition to the first part: a second part; the second portion includes imaging of all parts other than the head, for example, the person's image other than the head portrait.
In other embodiments, the first portion may include: imaging of the head and neck, the second portion may include: other parts of the head and neck are imaged.
In other embodiments, the target object may also be a person (i.e., a portion other than the head); the first part of the person may include: neck and/or extremities (hands and legs); the second part may include: shoulder, chest, waist, abdomen, crotch, etc.
In some embodiments, the first portion includes a plurality of portions; the second part may also comprise a plurality of parts. For example, the first part may comprise a head and a neck; the second part may comprise a part other than the head and neck.
In some embodiments, for adjusting the size and/or shape of the first part of the target object in the image, the user may only operate the deformation in one direction during the deformation, and if the deformation of the first part is finished, the subsequent presentation of the first part in the image may be abnormal, which is not intended by the user. In this embodiment, the image device automatically performs the deformation of the first portion in the second direction according to the deformation ratio of the first deformation in the first direction. Here, the second direction is perpendicular to the first direction. For example, in a two-dimensional planar coordinate system, if the first direction is the x-axis direction, the second direction may be the y-axis direction, and if the second direction is the y-axis direction, the first direction may be the x-axis direction.
The face shown in fig. 3 is provided with a deformed mesh in which deformed control points are provided. As can be seen from fig. 3, the grid points of the deformed grid can be moved in the lateral direction and the longitudinal direction, and the change of the pixels in the grid where the control points are located to the coordinate can be controlled by the movement of the control points, so that the deformation processing of the corresponding part of the image is realized.
The deformation ratio in the present embodiment may include: the dimensional ratio before and after deformation.
For example, before deformation, the first part occupies S1 pixels in the first direction; after the deformation, the first local occupies S2 pixels in the first direction, and the deformation ratio may be: S2/S1; in step S110, the first part is adjusted in equal proportion to the S2/S1 in the second direction, so that the deformation of the S2/S1 of the first part in the second direction is also achieved.
Of course, the above is merely an example description of the deformation ratio, and the specific implementation is not limited to the above example.
In some embodiments, the deformation ratio may further include: the morphological amplitude ratio before and after deformation; the morphology determines the shape of the first part present in the image, without necessarily being related to the size of the first part in the image.
The deformation grid may be utilized in this embodiment to assist in the deformation process of the first part. The grid points in the deformed grid are control points of deformation processing, and the coordinate change of the control points directly determines the conversion of pixel coordinates of pixels in the grid where the frame control points are located.
In some embodiments, the deformation may be: the first local deformation may be generated by a global deformation of the target object. In short, the deformation can be produced in various ways, and is not limited to any of the above.
The deforming process performed on the first portion in the second direction may be a partial deforming process based on a deformation ratio of the deformation.
If the step S110 is: and carrying out deformation equal to the deformation proportion on the first part in the second direction, so that the equal proportion deformation of the first part in two mutually perpendicular directions is realized. If the first part is deformed in equal proportion, the dimensions of the first part in two vertical directions are scaled in equal proportion after deformation; in this way, a first partial scaling of the size of the partial occupation can be achieved directly, by means of which scaling the size of the partial occupation in both directions can be achieved. For example, in a group photo including a plurality of persons, one user perceives that his head is larger or smaller, and may need to zoom his head, and with the method provided in this embodiment, the zooming of the head may be achieved without changing the five-sense ratio thereof.
As shown in fig. 4, the left-most original image in fig. 4 is subjected to a slimming process, which results in a head portion as shown in the middle of fig. 4 being formed by a shrinking process in the lateral direction as a first part, and at this time, the head portion has an elongation effect. The rightmost head of fig. 4 is scaled by a vertical process.
The center point of the first local deformed grid in the first direction is: a first center point; the processing of the deformation of the first local in the second direction according to the deformation proportion of the first local of the target object in the image includes: the coordinates of the first local deformed mesh are moved in the second direction such that a second center point of the first local deformed mesh in the second direction coincides with the first center point.
The first center point may be a center coordinate in a first direction of the first area partially covered by the deformed mesh. The second center point may be a center coordinate of the first region partially covered by the deformed mesh in the second direction. The coordinates of the center point in the first direction and in the second direction overlap before the first part does not participate in the deformation, and the coordinates of the first center point in the first direction move in the first direction after the deformation of the first part.
The deformation interpolation algorithm for generating the deformation is as follows: presetting a deformation interpolation algorithm;
the step S110 may include: and performing pixel coordinate mapping in the second direction by using the preset deformation interpolation algorithm and the first local deformation grid.
The grid points of the warped grid are subjected to pixel coordinate mapping, and pixels associated with the grid points are also required to be subjected to pixel coordinate mapping, but the association relationship between the coordinate mapping of different pixels and the coordinate mapping of the grid points is determined by the warped interpolation algorithm. Thus, smoothness between pixels of the target pixel coordinates after each pixel is mapped can be achieved by the morphing interpolation algorithm.
In this embodiment, the deformation of the first part in the first direction and the second direction may not only adopt the same deformation proportion, but also adopt the same deformation interpolation algorithm (i.e. the preset deformation interpolation algorithm), so that the internal structure of the deformed first part may maintain the original proportional relationship and/or morphology through the deformation processing in the second direction after the deformation, so as to reduce the undesired image effect caused by the deformation, thereby improving the effect of image deformation and user satisfaction.
The preset deformation interpolation algorithm comprises at least one of the following: a Bezier curve interpolation algorithm; spline curve interpolation algorithm.
If the target object is a portrait, the first part is a head, and the spline interpolation algorithm can be selected.
The target object further comprises: a second part different from the first part;
the method as shown in fig. 2 further comprises:
step S100: and carrying out overall deformation processing on the target object in the first direction so that the first local part deforms in the first direction.
In some embodiments, the deformation is introduced when the target object is subjected to a global deformation process in a first direction. For example, the first part is a head, and the first part is a part other than the head. For example, a figure in an image is subjected to slimming treatment, and in the process of the slimming treatment, the figure in the image is thinned, and at the same time, the head is thinned. This brain bag thinning is the deformation. However, after the brain bag becomes thin, the effect of lengthening the head is visually exhibited, and the obtained portrait is not beautiful in practice. In this embodiment, in order to avoid the unsightly appearance caused by such deformation, if the deformation is generated in the first direction, the deformation is automatically performed in the second direction in an equal proportion, so that the problems of poor image quality and low user satisfaction caused by the lengthening of the brain bag are reduced; in this embodiment, the deformation is performed in the second direction simultaneously.
Notably, are: in some embodiments, the step S1000 and the step S110 may be performed synchronously, or may be performed sequentially, for example, according to the method shown in fig. 2, step S100 is performed first, and then step S110 is performed. In other embodiments, the steps S100 and S110 may be performed synchronously, for example, the first deformation network is used to perform the deformation processing in the first direction, the second deformation network is used to perform the deformation processing in the second direction, the third deformation network is obtained by finally merging the deformed first deformation network and second deformation network, and the mapping of the pixel coordinates and the determination of the pixel values of the image are performed based on the third deformation network, so that the image processing efficiency is improved by parallel processing, and the mapping of the pixel coordinates and the determination of the pixel values are performed only once, so that the unnecessary calculation amount may be reduced; the processing load amount of the image device is reduced.
In some embodiments, the step S110 may include:
and if the deformation application is in an equal-proportion deformation mode, after the first local part is deformed in the first direction, carrying out deformation processing on the first local part in the second direction according to the deformation proportion of the deformation.
In this embodiment, the morphing application may be an image processing application running in an electronic device, and the image processing application may be: dedicated applications for performing image deformation processing, for example, various kinds of image-forming applications.
If the morphing application is in the equal proportion morphing mode, the image device automatically performs equal proportion morphing in the vertical direction by running the morphing application.
In some embodiments, it may be convenient for a user to manipulate the deformation in one direction while performing the image deformation; if the deformation is needed in equal proportion, the user needs to manually control the deformation in the other direction; obviously difficult to control. If the deformation application is in the equal-proportion deformation mode, the image equipment automatically executes equal-proportion deformation in the other direction, so that the user operation is simplified, and the image quality is improved.
In some embodiments, the method further comprises: if the deformation application is in a non-equal proportion deformation mode, outputting prompt information when the abnormal size proportion of the first part in the first direction and the second direction is detected; the prompt message is used for prompting the equal proportion deformation of the first part.
The prompt information may be: and outputting information which can prompt the first part to deform in equal proportion.
For example, the prompt information includes: the first prompt message and/or the second prompt message; the first prompting information is used for prompting whether the deformation application is switched to the equal-proportion deformation mode or not; the second prompting information is used for prompting the first local equal-proportion deformation in the unequal-proportion deformation mode.
In some embodiments, the morphing application may also be in a non-equal proportion morphing mode. I.e. in this mode the image device does not automatically deform in equal proportion. In the unequal ratio deformation mode, if a deformation instruction in the first direction is detected, performing deformation in the first direction; if deformation in the second direction is detected, deformation in the second direction is performed, and deformation in the direction in which no deformation instruction is detected is not performed.
In this embodiment, if the image device or the deformation application detects that the first part deforms in a certain direction, the first part generates abnormal dimensional proportions in two directions, and if such an image is directly output, the image device or the deformation application may not be wanted by the user or the user may not notice the image. In order to improve user experience, in this embodiment, such an image with a proportion abnormality is avoided being directly output, and in this embodiment, a prompt message is also output, where the prompt message may be: any information prompting the user whether the equal proportion deformation is needed.
The hint information may include: the first prompt information can be used for prompting the switching to the equal-proportion deformation mode, and if a switching instruction for switching to the equal-proportion deformation mode is detected, the deformation processing in the second direction is automatically performed after the switching to the equal-proportion deformation mode, so that the first part can be restored to or enter into the normal proportion range after the deformation processing in the second direction.
In some embodiments, the hint information may include: and second prompt information. The second prompt information may be: in the case of maintaining the deformation application in the unequal ratio deformation mode, the first portion of the abnormality is equal ratio deformed such that the dimensional ratio of the first portion in the first direction and the second direction is restored or switched to be within the normal ratio range. For example, a confirmation indication of the user acting on the second prompt is detected.
The first prompt information and/or the second prompt information can be in the form of a dialog box, and if the operation acting on the dialog box is detected, whether to confirm the indication or not is determined according to the space or the key operated by the operation.
For the first prompt message, if the first prompt message is a negative indication, the user is indicated to want the deformation application to be maintained in the unequal ratio deformation mode; if the user confirms the indication, the user wants to deform the application to enter the equal-proportion deformation mode. Thus, the image device or the morphing application can execute the corresponding operation according to the detected operation.
For the second prompt, if the indication is a negative indication, the user wants the deformation application to be maintained in the non-proportional deformation; if the user confirms the instruction, the user wants to deform the application to perform the equal-proportion deformation of the first local. If the second prompt information is output, a confirmation instruction of the user acting on the second prompt information is detected, after the first partial equal proportion deformation is executed, the deformation application or the image equipment can continuously detect whether the proportion is seriously disordered due to the deformation in the deformation process because the deformation state is maintained in the unequal proportion deformation state, and the proportion of the seriously disordered is one of the proportion abnormity. Then, the abnormal proportion is detected again, and prompt information and the like are output again.
In some embodiments, the method further comprises: and if the indication operation indicating the deformation mode is not detected, the deformation application enters the unequal ratio deformation mode.
In some cases, the unequal ratio deformation mode may be a default deformation mode, and if an indication operation specifically indicating the equal ratio deformation mode is detected, the deformation application defaults to be in the unequal ratio deformation mode.
In some embodiments, the method further comprises:
detecting a deformation mode indication operation;
determining whether the deformation application is in the equal-proportion deformation mode or the unequal-proportion deformation mode according to the indication operation;
if the deformation application is in the unequal ratio deformation mode, outputting prompt information when detecting that the size proportion of the first part in the first direction and the second direction is abnormal, wherein the prompt information comprises:
outputting the second prompt information when the unequal ratio deformation mode entering after the indication operation is detected and the proportion abnormality of the first local part in the first direction and the second direction is detected; otherwise, outputting the first prompt message.
If the deformation application is in the unequal ratio deformation mode, the method is entered based on the indication operation. If the user needs to be prompted again to switch to the equal-proportion deformation mode, if the first prompting information is repeatedly output, possibly the user is interfered by deformation processing, so in the embodiment, if the user enters the equal-proportion deformation mode based on the instruction operation input by the user, the second prompting information is output when the proportion abnormality is detected; otherwise, outputting the first prompt message.
