The embodiment of the application provides an image processing method, an image processing device, electronic equipment and a readable storage medium. The image processing apparatus may be integrated in an electronic device, which may be a server or a terminal.

In addition, as shown in FIG. 1, the image processing system may also include a memory 200 for storing data, such as text data.

It should be noted that, the schematic view of the image processing system shown in fig. 1 is only an example, and the image processing system and the scene described in the embodiments of the present application are for more clearly describing the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the image processing system and the appearance of a new service scene, the technical solutions provided in the embodiments of the present invention are equally applicable to similar technical problems.

Next, an image processing method provided in an embodiment of the present application, in which an electronic device is used as an execution body, is described beginning to be described, and in order to simplify and facilitate description, the execution body will be omitted in a subsequent method embodiment, and the image processing method includes: acquiring an image to be processed; performing target object extraction processing on the image to be processed to obtain a target object image; adding illumination shadows to the target object image to obtain a spot shadow image; and fusing the spotlight region shade corresponding to the image to be processed and the spotlight shadow image into the image to be processed to obtain a spotlight effect diagram.

Referring to fig. 2, fig. 2 is a schematic flow chart of an image processing method according to an embodiment of the present application. It should be noted that although a logical order is depicted in the flowchart, in some cases the steps depicted or described may be performed in a different order than presented herein. The image processing method specifically may include the following steps 201 to 204, in which:

201. and acquiring an image to be processed.

The image to be processed may refer to an image to which a spotlight special effect is to be added. For ease of understanding, referring to fig. 3, fig. 3 is a schematic diagram of a spotlight effect, where the spotlight effect may be understood as an effect that a part of an image area 301 is blocked in an image 300, and a part of the image area 302 is displayed to present a visual effect that an illumination range of a spotlight is focused on a specific object in the image area 302. 1. Presenting special effects of visual effects that the irradiation range of the spotlight is focused on a specific object; 2. shadow special effects of specific objects in the image to be processed.

In some embodiments, the user may open a functional interface for adding a spotlight effect in the image processing software, and input a to-be-processed image of the to-be-added spotlight effect in the functional interface.

It should be noted that, in order to facilitate calculation of the subsequent position, after the image to be processed is obtained, normalization processing may be performed on the position of each pixel point in the image to be processed, and the position of each pixel point may be normalized to be within the range of coordinates (0, 1), and when any position is referred to hereinafter, processing may be performed based on the normalized position.

202. And carrying out target object extraction processing on the image to be processed to obtain a target object image.

The target object extraction processing of the image to be processed may be a processing procedure of detecting an image area where the target object is located from the image to be processed, and clipping the image area to obtain an image with the same size as the image to be processed. It can be understood that the obtained target object image contains the image information in the image area where the target object is located, and the size of the target object image is the same as the size of the image to be processed.

The target object is an object to be added with the special effect of the spotlight in the image to be processed. The kind of the target object is not particularly limited in the embodiments of the present application, and the target object may refer to one of different kinds of people, animals, furniture, and the like. The specific kind of the target object may be set in advance by a developer of the image processing software.

In some embodiments, the target object may be one of a plurality of preset objects. For example, a developer may set a person, an animal, and furniture as preset objects, respectively, and set different virtual controls for different preset objects in the image processing software, each virtual control being used to trigger an extraction operation for a different preset object. When the user wants to add the special effect of the spotlight to the person in the image to be processed, the virtual control corresponding to the person can be operated, and the electronic device takes the person as a target object at this time, and step 202 is executed.

The image area of the target object in the image to be processed can be obtained by detecting the trained target detection model, and then the image area is cut to obtain the target object image. For example, training an open-source target detection model such as YOLO through a preset sample data set to obtain a trained target detection model, inputting an image to be processed into the trained target detection model to obtain an image area where a target object is located in the image to be processed, and cutting to obtain a target object image.

203. And adding an illumination shadow to the target object image to obtain a spot light shadow image.

An illuminated shadow can be understood as a blurred shadow that is generated at the edge of a target object by light striking the target object.

In some embodiments, edges of the target object may be detected and blurred to add an illumination shadow. For example, the edge of the target object in the target object image can be detected through edge detection algorithms such as a Sobel operator, a Kirsch operator, a compass operator and the like, and then the edge is blurred through filtering and the like so as to add illumination shadows.

204. And fusing the spotlight region shade corresponding to the image to be processed and the spotlight shadow image into the image to be processed to obtain a spotlight effect diagram.

The light-condensing area mask is a mask for showing a visual effect that the irradiation range of the spotlight is condensed on a specific object, and for convenience of understanding, fig. 3 is taken as an example. In fig. 3 the spotlight region mask may obstruct the image region 301 to present the visual effect that the illumination range of the spotlight is focused on a specific object in the image region 302.

In some embodiments, the spotlight region mask may be input by a user. For example, in the image processing software, a user can adjust the position of the center point of the light-gathering area mask in the image to be processed and the radius of the light-gathering area mask through a preset virtual control so as to generate a circular light-gathering area mask, and through setting the transparency of the light-gathering area mask, the image area of the image to be processed outside the light-gathering area mask can be covered.

For example, the electronic device may fuse the spotlight region mask corresponding to the image to be processed and the spotlight shadow image into the image to be processed in a manner of overlapping the layers, so as to obtain a spotlight effect diagram. For example, the layers may be sequentially arranged from top to bottom in the order of the spotlight region mask, spotlight shadow image, image to be processed, so as to obtain a spotlight effect map. It can be understood that the spotlight effect graph includes both the special effect of presenting the visual effect that the irradiation range of the spotlight is focused on the specific object and the shadow special effect of the specific object in the image to be processed, so that a more real spotlight special effect is provided.

In some embodiments, the image obtained by the method of overlapping the layers in step 204 includes three layers, so that the data size is large, and the excessive storage space of the device is occupied. Referring to fig. 4, at this time, the step of "fusing the spotlight region mask corresponding to the image to be processed and the spotlight shadow image into the image to be processed to obtain a spotlight effect diagram" includes:

401. and carrying out single-channel extraction on the spot shadow image to obtain a target shade of the spot shadow image.

Single channel extraction refers to extracting an image of one of the channels from the spot shadow image. For example, when the spot shadow image is an RGB image, an image of any one of R, G, B channels may be extracted from the spot shadow image as a target mask.

It will be appreciated that since the spot shadow image is an image with an added illumination shadow, there will be pixel values in the target mask for the region corresponding to the illumination shadow, and by taking the pixel values in the target mask as weights, the illumination shadow can be blended in the corresponding region in the image to be processed.

402. And mixing the pixel value of each pixel point in the spot light shadow image and the pixel value of each pixel point in the image to be processed according to the weight of each pixel point in the target shade to obtain a mixed image.

Illustratively, the pixel value of each pixel in the spot-light image, and the pixel value of each pixel in the image to be processed, may be blended by the following algorithm formula (1):

highshadow=mix (blursshadow, lightTex, blurmsk) algorithm formula (1)

Wherein highShadow refers to the pixel value in the blended image, blurShadow refers to the pixel value in the spot shadow image, lightTex refers to the pixel value in the image to be processed, blurMask refers to the weight in the target mask, mix refers to the blending function.

403. And merging the light focusing area shade corresponding to the image to be processed into the mixed image to obtain a spotlight effect diagram.

In step 403, the layer overlapping or pixel value blending may be performed. For example, a spotlight region mask may be placed over the blended image to obtain a spotlight effect image comprising two layers. Alternatively, the following algorithm formula (2) may be adopted, wherein the pixel values in the light-condensing region mask are used as weights, and the pixel values in the mixed image are mixed with preset pixel values for transparentization, so that the image region outside the light-condensing region of the spotlight effect graph is transparentized, and the spotlight effect graph is obtained:

finalcolor=mix (highShadow, vec (0.0), circle. R) algorithm formula (2)

Where finalColor refers to the pixel values in the spotlight effect map, highShadow refers to the pixel values in the blended image, circle. R refers to the spotlight region mask, vec (0.0) is the preset pixel values for blending, to transparence the image region outside the spotlight region of the spotlight effect map, and mix refers to the blending function.

It can be seen that by the method from step 401 to step 403, the number of layers in the spotlight effect diagram can be reduced, the data amount of the spotlight effect diagram can be reduced, and in the process of obtaining the blended image by blending, the weights corresponding to the other image areas except the image area containing the target object in the target mask are all 0, so that the other image areas except the image area containing the target object in the image to be processed are not affected.

In some embodiments, in order to improve the display effect of the spotlight effect graph, the image to be processed may be first brightened, and the brightened image to be processed is used as a new image to be processed. Referring to fig. 5, at this time, before the step of "performing the target object extraction process on the image to be processed to obtain the target object image", the method further includes:

501. And inquiring a preset pixel brightening table to obtain a brightening pixel value corresponding to the initial pixel value of each pixel point in the image to be processed.

The pixel brightening table is used for storing the pixel values after brightening corresponding to different pixel values, and the pixel value of each pixel point in the image to be processed is updated by inquiring the pixel brightening table, so that the image to be processed can be brightened. Illustratively, the pixel brightness table may refer to a LUT (Look Up Table) map.

The pixel brightness table may be designed in advance by a developer of the image processing software and stored in a background database of the image processing software or a background database of the electronic device, and when step 501 is executed, the electronic device may directly acquire the pixel brightness table.

502. Updating the initial pixel value of each pixel point by the corresponding brightness-improving pixel value of each pixel point to obtain each updated pixel point and a new image to be processed formed by each updated pixel point.

Although a method of adding an illumination shadow is provided in step 203, this method requires identifying the edges of the target object to achieve this, which is inefficient. The present application also provides a method for adding an illumination shadow through gaussian blur, namely, the steps of adding an illumination shadow to the target object image to obtain a spot shadow image, including:

And carrying out Gaussian blur processing on the target object image to obtain a spot shadow image.

The Gaussian blur processing is used for carrying out blur processing on the edge of the target object in the target object image so as to add illumination shadows.

When gaussian blur is performed, the electronic device may perform weighted average processing of adjacent pixel values on each pixel point in the target object image, and when average processing is performed on pixel points at an edge of the target object, since pixel values of adjacent pixel points that partially belong to the target object are not 0 and pixel values of adjacent pixel points that partially do not belong to the target object are 0, a blur effect may be provided for the edge of the target object, and even if the pixel values of the adjacent pixel points that do not belong to the target object are unchanged after weighted average processing. And if the illumination shadow is added through Gaussian blur and the spotlight effect diagram is obtained through a mixing mode, the illumination shadow can be added in the spotlight effect diagram on the one hand, and on the other hand, the image noise in the spotlight effect diagram can be reduced through Gaussian blur, and detailed description is omitted for specific reasons that the Gaussian blur can reduce the image noise.

In some embodiments, the present application further provides a method for enabling a user to adjust pixel values in an image of a target object to make an image beautify and improve a visual effect of the target object in a spotlight effect map. The step of adding an illumination shadow to the target object image to obtain a spot shadow image, before the step of adding the illumination shadow to the target object image to obtain a spot shadow image, further comprises:

Wherein the adjustment operation includes a hue adjustment operation, a saturation adjustment operation, a brightness adjustment operation, and/or a transparency adjustment operation.

It is understood that when the adjustment operation is a hue adjustment operation, a saturation adjustment operation, a brightness adjustment operation, and/or a transparency adjustment operation, the pixel value adjustment parameter may refer to a hue adjustment value, a saturation adjustment value, a brightness adjustment value, and/or a transparency adjustment value.

For example, the user may perform the adjustment operation through a virtual control preset in the functional interface for adding the special effects of the spotlight. For example, the user may reduce or increase the hue, saturation, brightness, and/or transparency of each pixel point in the target object image as a whole by triggering the virtual control. Or, in order to avoid adjusting other image areas except for the image area containing the target object in the target object image, and influence the visual effect of the mixed spotlight effect image, a single-channel image in the target object image can be extracted by a single-channel extraction method, the extracted single-channel image is used as a mask, and according to the weight of each pixel point in the mask, the pixel value adjusting parameter corresponding to each pixel point and the pixel value of each pixel point in the target object image are mixed, and the specific mixing method can refer to the algorithm formula and is not repeated.

In some embodiments, to improve the display effect after the light-condensing region mask is fused into the image to be processed, the edge of the light-condensing region may be processed to obtain the light-condensing region mask in which the edge of the light-condensing region exhibits a gradual change effect. Referring to fig. 6, at this time, before the step of fusing the preset spotlight region mask and the spotlight shadow image into the image to be processed to obtain the spotlight effect map, the method further includes:

601. and acquiring a first light condensing area in the image to be processed and a second light condensing area in the first light condensing area.

In some embodiments, the first light-gathering area and the second light-gathering area may be set by a user, and a specific setting method may refer to the above and will not be described again.

In other embodiments, to reduce the complexity of the user operation, the electronic device may further automatically determine the first light focusing region and the second light focusing region. Namely, the step of acquiring a first light condensing area in the image to be processed and a second light condensing area in the first light condensing area comprises the following steps:

(1.1) acquiring an image position of a target object in the image to be processed.

The method of acquiring the image position may refer to the method of detecting the target object above. It should be noted that, if the target object has been detected, the step (1.1) may be performed without detecting the image position of the target object again. Or if the image position is obtained by performing the step (1.1), the image position of the target object does not need to be detected again when the target object extraction process is performed.

(1.2) determining a first light gathering area according to the image position and a preset first area size.

(1.3) determining a second light condensing region in the first light condensing region according to the image position and a preset second region size, wherein the second region size is smaller than the first region size.

Specific values of the first area size and the second area size may be changed according to requirements of an actual scene, which is not limited in the embodiment of the present application.

The purpose of acquiring two light gathering areas is to determine the area between the two light gathering areas where a gradual change needs to be produced. For example, when the first light-condensing region and the second light-condensing region are both circular regions, a ring-shaped region that is not overlapped between the first light-condensing region and the second light-condensing region may be used as a region where gradual change is required to be generated.

602. And generating an initial mask of the image to be processed according to the position of the first light gathering region, wherein the initial mask comprises a third light gathering region corresponding to the first light gathering region and a fourth light gathering region corresponding to the second light gathering region.

It will be appreciated that the position of the third light concentrating region in the initial mask is the same as the position of the first light concentrating region in the image to be processed, and that the position of the fourth light concentrating region in the initial mask is the same as the position of the second light concentrating region in the image to be processed.

603. And carrying out gradual change treatment on the non-overlapped area between the third light condensation area and the fourth light condensation area to obtain a light condensation area shade corresponding to the image to be treated.

For example, the gradual change may be performed by feathering (that is, a non-overlapping region between the third light-focusing region and the fourth light-focusing region, by a smoothstep algorithm or the like, so as to obtain a light-focusing region mask that exhibits a gradual change effect in the non-overlapping region, where a specific parameter of the feathering may be a preset value or a value input by a user, which is not limited in the embodiment of the present application.

It can be seen that, by the method from step 601 to step 603, a spotlight region mask with a gradually changed visual effect at the edge of the spotlight region can be obtained, so as to improve the visual effect of the spotlight effect graph.

In order to better implement the image processing method in the embodiment of the present application, an image processing apparatus is further provided in the embodiment of the present application, as shown in fig. 7, which is a schematic structural diagram of an embodiment of the image processing apparatus in the embodiment of the present application, where the image processing apparatus 700 includes:
