Abstract

The present disclosure provides a watermark image processing method and apparatus, a device and a computer readable storage medium. In the embodiments of the present disclosure, it is feasible to obtain at least one similar image approximate to the watermark image according to the watermark image including the watermark, and obtain a replaceable image of each similar image of said at least one similar image in the watermark area, according to a watermark area where the watermark is located in the watermark image so that it is possible to obtain a carrier image not including the watermark, according to the watermark image and the replaceable image of said each similar image in the watermark area. Since the replaceable image of the similar image in the watermark area is employed to obtain the carrier image not including the watermark, the valid content in the watermark image covered by the watermark is restored and thereby the reliability of the image is improved.

First claim

The invention claimed is:

1. A watermark image processing method, wherein the method comprises:
according to a watermark image including a watermark, obtaining, by image search processing for the watermark image, at least one similar image whose valid content is substantially consistent with the watermark image;
according to a watermark area where the watermark is located in the watermark image, obtaining a replaceable image area corresponding to the watermark area of the watermark image but without a watermark in said at least one similar image;
obtaining a target image not including the watermark by replacing the watermark area of the watermark image with the replaceable image area.

2. The method according to claim 1 , wherein the obtaining a target image not including the watermark by replacing the watermark area of the watermark image with the replaceable image area comprises:
using an image processing technology to obtain the target image not including the watermark by replacing the watermark area of the watermark image with the replaceable image area.

3. The method according to claim 2 , wherein the image processing technology comprises at least one of an image matching processing technology and an image concatenation processing technology.

4. A device, wherein the device comprises:
one or more processors;
a storage for storing one or more programs,
said one or more programs, when executed by said one or more processors, enable said one or more processors to implement a watermark image processing method, wherein the method comprises:
according to a watermark image including a watermark, obtaining, by image search processing for the watermark image, at least one similar image whose valid content is substantially consistent with the watermark image;
according to a watermark area where the watermark is located in the watermark image, obtaining a replaceable image area corresponding to the watermark area of the watermark image but without a watermark in said at least one similar image;
obtaining a target image not including the watermark by replacing the watermark area of the watermark image with the replaceable image area.

5. The device according to claim 4 , wherein the obtaining a target image not including the watermark by replacing the watermark area of the watermark image with the replaceable image area comprises:
using an image processing technology to obtain the target image not including the watermark by replacing the watermark area of the watermark image with the replaceable image area.

6. The device according to claim 5 , wherein the image processing technology comprises at least one of an image matching processing technology and an image concatenation processing technology.

7. A non-transitory computer readable storage medium on which a computer program is stored, wherein the program, when executed by a processor, implements a watermark image processing method, wherein the method comprises:
according to a watermark image including a watermark, obtaining, by image search processing for the watermark image, at least one similar image whose valid content is substantially consistent with the watermark image;
according to a watermark area where the watermark is located in the watermark image, obtaining a replaceable image area corresponding to the watermark area of the watermark image but without a watermark in said at least one similar image;
obtaining a target image not including the watermark by replacing the watermark area of the watermark image with the replaceable image area.

8. The non-transitory computer readable storage medium according to claim 7 , wherein the obtaining a target image not including the watermark by replacing the watermark area of the watermark image with the replaceable image area comprises:
using an image processing technology to obtain the target image not including the watermark by replacing the watermark area of the watermark image with the replaceable image area.

9. The non-transitory computer readable storage medium according to claim 8 , wherein the image processing technology comprises at least one of an image matching processing technology and an image concatenation processing technology.
