Embodiment 1

[0035] like figure 1 As shown, it is a flow chart of an image blurring processing method proposed by the present invention.

[0036] refer to figure 1 , an image blurring processing method, comprising the following steps:

[0037] Step 101, identifying blurred areas on the initial image;

[0038] Step 102, processing the initial image to obtain an enlarged image;

[0039] Step 103, process the enlarged image to obtain the information of the difference enlarged area and form a replacement image;

[0040] Step 104, covering the blurred area on the original image with the replacement image to form a new image.

[0041] In the embodiment of the present invention, firstly, by shrinking the blurred area of ​​the image, the blurred area is made invisible, thereby eliminating the blurred image; then, by amplifying the difference, the image after blurring is enlarged to the original size, thereby obtaining the same size as the blurred area of ​​the original image. The difference v...

Embodiment 2

[0062] Based on the same inventive concept as the image blur processing method in the foregoing embodiments, the present invention also provides an image blur processing device based on feature matching and weighted average.

[0063] see figure 2 , is a structural diagram of an image blur processing device proposed by the present invention.

[0064] like figure 2 Shown, a kind of image fuzzy processing device comprises:

[0065] A blurred area identification unit 201, identifying a blurred area on the initial image;

[0066] Enlarged image processing unit 202, which processes the initial image to obtain the enlarged image;

[0067] The replacement image processing unit 203 is used to process the enlarged image to obtain difference amplification area information and form a replacement image;

[0068] The new graphics processing unit 204 overlays the replacement image on the blurred area of ​​the original image to form a new image.

[0069] Various variations and specific...

Embodiment 3

[0071] An image blurring processing device based on feature matching and weighted average, comprising a memory, a processor, and a computer program stored in the memory and operable on the processor, wherein the processor executes the The computer program realizes an image blurring processing method as described above.

[0072] The processor can be a central processing unit (Central Processing Unit, CPU), or other general-purpose processors, digital signal processors (Digital Signal Processor, DSP), application specific integrated circuits (Application Specific Integrated Circuit, ASIC) ), off-the-shelf programmable gate array (Field-Programmable Gate Array, FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or this processor can also be any conventional processor etc., described processor is the control center of described a kind of image fuzzy processin...

Abstract

The invention discloses an image blurring processing method. The method comprises the following steps: identifying a blurred region on an initial image; processing the initial image to obtain an amplified image; processing the magnified image to obtain difference magnified area information and form a replacement image; and covering the blurred area on the initial image with the replacement image to form a new image. The invention further provides an image blurring processing device, image blurring processing equipment and a storage medium. The image blurring area is processed through image scaling and the linear difference value, the algorithm is simple, the image blurring processing efficiency is high, and the image processing efficiency can be improved on the premise that the image is ensured to be clear.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image blurring processing method, device, equipment and storage medium. Background technique [0002] Today, as the network is more and more widely used, the expression of digital images is more intuitive and vivid, and can clearly convey all the information in the pictures. [0003] However, the image is prone to blurring during playback, and the image blurring is caused by the distortion of the digital image. An electronic image converted from a physical image. [0004] The most important feature of the image module is that the edge sharpness of the digital image decreases and the spatial details are missing, resulting in unclear boundaries between objects, unable to highlight the grayscale color changes of various objects and digital images, and weakening some details. In this way, the image display cannot be clearly displayed, and the image quality is re...
