Abstract
The invention discloses a kind of similar decision method of local pixel gray scale picture, comprise the following steps：First step compressed picture；Second step gradation conversion；3rd step calculates gray average or golden ratio value；The gray scale of 4th step compared pixels；5th step hashes；The hash contrast of 6th step.The present invention is similar to judge that (three pictures elected have one for similar or identical photo to rate 33% or so, although 2 times of photo can be selected more, but similar or identical photo will not be omitted), but, it can help manually during judgement of encroaching right, similar picture is not omitted, is substantially reduced scope；Improve searching efficiency.
Description
Technical field
The present invention relates to image processing field, the similar decision method of more particularly to a kind of local pixel gray scale picture.
Background technology
As intellectual property obtains the attention of society, IP dispute is also more and more, and picture is as intellectual property
Important component, abuse take place frequently, but picture obligee is difficult to find abuse, causes picture obligee's right-safeguarding to be stranded
It is difficult.At present, the whole network crawler technology can obtain the pictorial information of magnanimity, but how to screen and scheme in the pictorial information of magnanimity
The similar picture of piece obligee, is a problem to be solved.With current technology, it is difficult to computer method directly to figure
Piece carries out infringement judgement, but can screen mass picture, excludes the picture of dissmilarity, and a large amount of screening figures are saved for artificial judgment
Manual time's cost of piece.
Applicant has submitted portion and has been based on the similar decision method patent application of local pixel gray scale picture, contracts in picture ratio
Put, light and shade change etc., can obtain uniformity as a result, when still using picture for part, judging result is inaccurate.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of similar judgement side of local pixel gray scale picture
Method.
A kind of similar decision method of local pixel gray scale picture provided by the invention, comprises the following steps：
The local picture of first step interception
Picture creative picture in source is intercepted out.
Second step segmentation contrast picture
Contrast picture is divided into N number of part.
3rd step compressed picture
Contrast picture after source picture and segmentation is compressed to 8 pixel x8 pixels, totally 64 pixels.
4th step gray scale is changed
By compressed picture, the picture of 64 grades of gray scales is converted to.
5th step calculates gray average or golden ratio value
Calculate the gray average or golden ratio value of all pixels in the picture of 64 grades of gray scales, the golden ratio value
For：Gray average/0.618.
The gray scale of 6th step compared pixels
By the gray value of each pixel compared with gray average or golden ratio value, more than or equal to gray average or
Golden ratio value is denoted as 1, and 0 is denoted as less than gray average or golden ratio value.
7th step hashes
The comparative result of 7th step is hashed, the bigit of composition one 64.
The hash contrast of 8th step
To the hash of the contrast picture after source picture and segmentation, how many difference in 64 obtained；Less than 5 to be similar
Or same photograph.
Beneficial effect：The present invention is individually intercepted by that will contrast picture segmentation, while by the part of source picture creativeness, is allowed
Creative part is individually contrasted with contrasting the partitioning portion of picture, if similar, contrast picture is doubtful infringement picture.
Brief description of the drawings
The similar decision method source file part sectional drawing compressed picture schematic diagram of Fig. 1 local pixel gray scale pictures of the present invention.
The similar decision method source file part sectional drawing gradation conversion schematic diagram of Fig. 2 local pixel gray scale pictures of the present invention.
The similar decision method contrast picture segmentation gradation conversion schematic diagram of Fig. 3 local pixel gray scale pictures of the present invention.
Embodiment
Embodiment：Fig. 1 be refer to Fig. 3
The local picture of first step interception
Picture creative picture in source is intercepted out.
Second step segmentation contrast picture
Contrast picture is divided into 4 parts.
3rd step compressed picture
Contrast picture after source picture and segmentation is compressed to 8 pixel x8 pixels, totally 64 pixels.
4th step gray scale is changed
By compressed picture, the picture of 64 grades of gray scales is converted to.
5th step calculates gray average or golden ratio value
Calculate the gray average or golden ratio value of all pixels in the picture of 64 grades of gray scales, the golden ratio value
For：Gray average/0.618.
The gray scale of 6th step compared pixels
By the gray value of each pixel compared with gray average or golden ratio value, more than or equal to gray average or
Golden ratio value is denoted as 1, and 0 is denoted as less than gray average or golden ratio value.
7th step hashes
The comparative result of 7th step is hashed, the bigit of composition one 64.
The hash contrast of 8th step
To the hash of the contrast picture after source picture and segmentation, how many difference in 64 obtained；Less than 5 to be similar
Or same photograph.
With reference to Fig. 2 and Fig. 3, can determine whether, the part of source file portion intercepts, it is identical with two parts for contrasting picture, say
Bright contrast picture applies the creation part of source picture, belongs to infringement picture.
