Problems solved by technology

[0004] However, both of the above methods have geometrically changed the final image of the area used; making the image shape of the first area and the second area slightly different will not be able to discern the content used in the final composite image. Which area is provided, and keeping the information unchanged in some applications is a basic requirement; due to such technical shortcomings, this type of method can only be used for entertainment applications

Embodiment approach

[0139] Embodiment 8 of the present invention provides a specific implementation of a device for replacing a local area in an image that can implement all the steps in the above method for replacing a local area in an image. The device for replacing a local area in an image specifically includes the following content:

[0140] A memory, a processor, and a computer program stored on the memory and operable on the processor. When the processor executes the computer program, the steps of any one of the replacement methods are realized, for example, the following steps are realized:

[0141] Step 100: Obtain feature points and position information of feature points of the first area in the reference image and the second area in the replacement image respectively; wherein, the area attribute of the first area in the reference image is the same as the The area properties of the two areas in the reference image are the same.

[0142] Step 200: Perform foreground segmentation processi...

Abstract

The invention provides an image local area replacing method and device and a storage medium. The replacing method comprises the following steps: obtaining feature points and position information of the feature points of a first area in a reference image and a second area in a replacement image respectively; carrying out foreground segmentation processing on the first area and the second area; according to the position information of the feature points, to begin with, carrying out global deformation processing on the replacement image to enable difference in size and position between the second area in the replacement image obtained after deformation processing and the first area to be within a preset range; then, carrying out local deformation processing on the first area in the reference image and adjacent areas; and replacing the first area obtained after deformation processing with the second area obtained after deformation processing to obtain a reference image comprising the second area. The method can change the reference image for replacement in a minimum degree under the premise of ensuring that the features of the replaced image do not change in the replacing process, so that natural degree of the image obtained after replacement is improved, and the image is allowed to have no trace of synthesis when seen by naked eyes.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method, device and storage medium for replacing a local area in an image. Background technique [0002] With the development of intelligent equipment in today's society, image processing has become an indispensable part of people's life. Whether it is professional image processing at work or entertainment image processing in life, the most important image processing method is One is to replace a local area in the image to obtain the replaced image required for work or entertainment, so that the processing method of the replaced image can be used to accelerate the selection of virtual experience, save the cost of image synthesis and enhance the image Fun synthesis of entertainment. [0003] At present, there are mainly two ways to replace the local area in the image. The first way is to extract the feature point set of the first area image and the corresponding "cutout...
