Embodiment 1
[0065] In this embodiment, an image double exposure fusion method is provided, please refer to figure 1 , which shows a flow chart of the image double exposure fusion method provided by the present application, which may include the following steps:
[0066] Step S11: Perform face control point recognition on the original face image to obtain a face region map.
[0067] Wherein, the process of identifying the face control points on the original face image is the same as the process of identifying the face control points in the prior art, and will be described in detail here.
[0068] In this embodiment, the original face image can be found in figure 2 ,right figure 2 After face control point recognition is performed on the original face image shown, the obtained face area map can be found in image 3 .
[0069] Step S12: Perform brightness filling on the face area map to obtain a face weight map.
[0070] In this example, for image 3 The shown face area map is filled ...
Embodiment 2
[0103] Corresponding to the above method embodiments, this embodiment provides an image double exposure fusion device, please refer to Figure 12 , the image double exposure fusion device includes: an identification module 121 , a filling module 122 , a first fusion module 123 , a processing module 124 , a second fusion module 125 and a third fusion module 126 .
[0104]The recognition module 121 is configured to perform face control point recognition on the original face image to obtain a face region map.
[0105] The filling module 122 is configured to perform brightness filling on the face region map to obtain a face weight map.
[0106] The first fusion module 123 is configured to perform weight fusion on the face weight map and the single-channel image of the original face image to obtain a fusion weight map.
[0107] The processing module 124 is configured to perform soft light processing on the original face image and the original background image to obtain a soft ligh...

Abstract
The invention provides a double exposure fusion method and device for an image. The double exposure fusion method for the image comprises the steps of performing human face control point recognition on an original face image, and obtaining a face region graph; performing brightness filling on the face region graph, and obtaining a face weight graph; performing weight fusion on the face weight graph and a single-channel image of the original face image, and obtaining a fusion weight graph; performing soft light processing on the original face image and an original background image, obtaining a soft light processing graph, performing color filter processing on the original face image and the original background image, and obtaining a color filter processing graph; performing fusion processing on the soft light processing graph and the color filter processing graph, and obtaining an image to be fused; and performing fusion processing on the original face image and the image to be fused according to the fusion weight graph, and obtaining a double exposure fusion image. According to the double exposure fusion method provided by the invention, the double exposure effect of the face image in the double exposure fusion image is better through the above manner, so that the double exposure fusion image is more nature.
Description
technical field [0001] The present application relates to the field of image processing, in particular to an image double exposure fusion method and device. Background technique [0002] Regarding the fusion of digital images in different scenes, the current more common methods are: color filtering, multiplication, soft light and strong light, etc. [0003] However, for the double-exposure fusion of person images, the above method has the problem of partial overexposure or underexposure, resulting in unnatural images after double-exposure fusion of person images. Contents of the invention [0004] In order to solve the above technical problems, the embodiment of the present application provides an image double exposure fusion method and device to achieve a better double exposure effect of the face image in the double exposure fusion image, so as to make the double exposure fusion image more natural. , the technical scheme is as follows: [0005] An image double exposure ...
