Fig. 2 is the structural representation that automatically car plate in picture is carried out mosaic processing device of the present invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the present invention is further elaborated.Should be appreciated that embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, the invention discloses a kind of method of automatically car plate in picture being carried out mosaic processing, comprise the following steps:
S1, receives the pending picture that includes license plate image;
S2, carries out analyzing and processing to the described picture receiving, the particular location of license plate image in described picture described in analyzing and positioning; S2 is specially:
S21, adopts successively when the described picture receiving is carried out to analyzing and processing with the following method and processes:
Picture inverse; Picture gray processing; Picture highlights; Gaussian filtering; Obtain the picture after rough handling;
S22, processes the picture after described rough handling successively by the following method:
Binaryzation; Remove noise; Use 2 × 6 matrix coarse positionings; Obtain four limits of car plate, thereby determine the particular location of car plate.
S3, carries out mosaic processing by the position of described license plate image, and saves as new picture.
After S3, can also have the following steps:
S4, is published to the described new picture of preserving in webpage.
In the time having plurality of pictures to process, repeating step S1-S3, can be to plurality of pictures batch processing.
As shown in Figure 2, the invention discloses a kind of device that automatically car plate in picture is carried out mosaic processing, comprising: picture receiver module, for receiving the pending picture that includes license plate image; Picture analyzing module, for the described picture receiving is carried out to analyzing and processing, the particular location of license plate image in described picture described in analyzing and positioning; Picture stamp module, for mosaic processing is carried out in the position of described license plate image, and saves as new picture.
The described device that automatically car plate in picture is carried out mosaic processing, also comprises: picture release module, and for the described new picture of preserving is published to webpage.
Described picture analyzing module, comprising:
Just processing module of picture, adopts successively with the following method when the described picture receiving is carried out to analyzing and processing and processes: picture inverse; Picture gray processing; Picture highlights; Gaussian filtering; Obtain the picture after rough handling;
Car plate locating module, for processing by the following method successively the picture after described rough handling: binaryzation; Remove noise; Use 2 × 6 matrix coarse positionings; Obtain four limits of car plate, thereby determine the particular location of car plate.
Concrete, image is just processed and is comprised: the gray processing of image, binaryzation, filtering etc., the reason of gray processing: first image before treatment is all generally that coloured image true color image claims again RGB image, comprising a large amount of colouring informations with the color coloured image of R, G, a pixel of tri-representation in components of B, storage overhead is large, and processing speed is slow.
Image, through after gray processing, because image itself exists many noises, also needs further processing, now just need to use noise filter image is processed.Gaussian filter is the linear smoothing wave filter of selecting weights according to the shape of Gaussian function.Gaussian filter has good effect to the noise of removing Normal Distribution.
In RGB model, if R=G=B, color represents a kind of greyscale color, and wherein the value of R=G=B is called gray-scale value.What in the license plate locating method in the present invention, adopt is weighted value method.
Bianry image refers in entire image picture the only image of black, white two-value, and the advantage of binaryzation is: the speed of processing is fast, cost is low.Binaryzation: it is 0 that the pixel that is less than threshold value for gray-scale value directly arranges gray-scale value; The pixel that gray-scale value is greater than threshold value is directly set to 255, and the successful standard of license plate image binaryzation is: characters on license plate is separated with car plate background.
In processing procedure, use following code:
The processing of picture inverse:
The processing of picture gray processing:
Gaussian filtering:
Image binaryzation:
Remove noise:
Use 2 × 6 matrix coarse positionings:
Find and obtain four limits of car plate:
By adopting technique scheme disclosed by the invention, obtain following useful effect:
Technical scheme of the present invention has realized, in the time of user Fa Tu automatically to the car plate in picture carry out mosaic processing more fast, function easily, save user issuing before picture the trouble of picture by oneself, in addition owing to being use Same Way processing picture, also make picture after treatment and original image difference change less, after issue, can not affect the aesthetics of whole webpage, improved efficiency, promoted user's experience simultaneously, simultaneously can also batch processing picture.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be looked protection scope of the present invention.
