Embodiment 1

[0029] figure 1 It is a flow chart of an image processing method provided in Embodiment 1 of the present application. see figure 1 , the method includes the following steps:

[0030] 101. Perform feature extraction on the image to be processed, and obtain at least six-channel feature maps, wherein the at least six-channel feature maps include: the first corner point feature map used to represent the upper left corner information of the image content of the image to be processed, and used to represent the image to be processed The second corner feature map of the lower left corner information of the picture content of the processed picture, the third corner feature map of the upper right corner information used to represent the picture content of the picture to be processed, and the lower right corner information of the picture content of the picture to be processed The fourth corner point feature map, the fifth corner point feature map and the sixth corner point feature map ...

Embodiment 2

[0045] In this embodiment, the seven-channel feature map is used, the first boundary point position is the left boundary point position located on the left boundary of the picture content of the picture to be processed, and the second boundary point position is located on the right side of the picture content of the picture to be processed. Taking the position of the right boundary point on the boundary as an example, a picture processing method provided in Embodiment 2 of the present application is described in detail. However, those skilled in the art should understand that, using the six-channel feature map as described in Embodiment 1 or feature maps with more channels than the seven-channel feature map, or the position of the first boundary point and the position of the second boundary point are Positions on other borders of the picture content of the picture to be processed can refer to this embodiment to implement the picture processing solution of the present applicatio...

Embodiment 3

[0117] Figure 8 It is a schematic diagram of an image processing device provided in Embodiment 3 of the present application, see Figure 8 , the device consists of:

[0118] A processing module 801, configured to perform feature extraction on the picture to be processed, and obtain at least six-channel feature map, wherein the at least six-channel feature map includes: the first information used to characterize the upper left corner information of the picture content of the picture to be processed A corner point feature map, a second corner point feature map used to characterize the lower left corner information of the picture content of the picture to be processed, a third corner point feature map used to characterize the upper right corner information of the picture content of the picture to be processed, A fourth corner point feature map used to characterize the lower right corner information of the picture content of the picture to be processed, and a fifth corner point ...

Abstract

The embodiment of the invention provides a picture processing method and device, electronic equipment and a computer storage medium, and the method comprises the steps: carrying out the feature extraction of a to-be-processed picture, obtaining a first angular point feature map for representing top left corner information of picture content of a to-be-processed picture, a second angular point feature map for representing bottom left corner information of the picture content, a third angular point feature map for representing top right corner information of the picture content, a fourth angular point feature map for representing bottom right corner information of the picture content; and a fifth corner feature map and a sixth corner feature map which are used for representing two opposite sides corresponding to the picture content; determining an upper left corner position, a lower left corner position, an upper right corner position, a lower right corner position, a first boundary point position and a second boundary point position of the picture content according to the at least six-channel feature map; and correcting the to-be-processed picture according to the angular point position to obtain a corrected picture. According to the scheme, the original content in the picture can be better reserved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an image processing method, device, electronic equipment and computer storage medium. Background technique [0002] Pictures are widely used in people's work and life, but in common scenarios, many pictures, especially pictures with text or pictures taken by users, will have a certain deformed angle, making the content appear to a certain extent. Distortion, for example, presenting a certain angle (such as narrow at the top and wide at the bottom, wide at the top and narrow at the bottom, etc.). Therefore, in order to better obtain the picture content carried in the picture, it is necessary to correct the picture. [0003] At present, a common method for image correction processing is to find four straight lines on the edge of the image content through Hough transform, and then perform perspective transformation on the image to obtain the final result. [0004] Howe...
