Abstract
The invention discloses a kind of similar decision method of picture based on conversion lines, source picture is divided into M N*N matrix, in order mark 1,2,3 ... ... M.Contrast picture is divided into M N*N matrix, in order mark 1 ', 2 ', 3 ' ... ... M '.By source picture, the element for all N*N matrixes for contrasting picture, according to gray scale assignment, the N 1 that is followed successively by 0,1 from low to high ....By the outer rim line of the matrix element of same grayscale value, and " 1 " is entered as again, the matrix element of all same grayscale values is entered as " 0 " again inside line, only contrasts in source picture and contrast picture, the assignment of " 1 " position is entered as, obtains the similar proportion of each contrast.The similar proportion obtained according to the 4th step, source picture is calculated with contrasting the similarity of picture.
Description
Technical field
The present invention relates to image processing field, more particularly to a kind of similar decision method of picture based on conversion lines.
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, it is to need to solve the problems, such as.With current technology, it is difficult to computer method directly to figure
Piece carries out infringement judgement, but can screen mass picture, and manual time's cost of a large amount of screening pictures is saved for artificial judgment.
To solve the above problems, applicant has applied for entitled " a kind of picture similar decision method ", Application No.
" 2017111545551 ", this method reduce the treating capacity of colour information by the way that two pictures to be carried out to the contrast of gray scale；It is right
Picture enters row matrix and gray scale same order and divided, can meet same photograph, color is scaled, scalable in proportion to wait operation
The similar judgement of photo afterwards, but if the matrix quantity of division is bigger, gray value is contrasted one by one, amount of calculation is huge, expends
Time is more.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the invention provides a kind of similar judgement of picture based on conversion lines
Method.
A kind of similar decision method of picture based on conversion lines provided by the invention, comprises the following steps：
The first step：Source picture is divided into M N*N matrix, in order mark 1,2,3 ... ... M.
Second step：Contrast picture is divided into M N*N matrix, in order mark 1 ', 2 ', 3 ' ... ... M '.
3rd step：By source picture, the element for all N*N matrixes for contrasting picture, according to gray scale assignment, from low to high successively
The N-1 for 0,1 ...；Wherein, 0 white is represented；N-1 represents black.
4th step：By the outer rim line of the matrix element of same grayscale value, and " 1 " is entered as again, it is all inside line
The matrix element of same grayscale value is entered as " 0 " again, only contrasts in source picture and contrast picture, is entered as the tax of " 1 " position
Value, obtains the similar proportion of each contrast.
5th step：The similar proportion obtained according to the 4th step, source picture is calculated with contrasting the similarity of picture.
Preferably, the M is 16,64 or 128.
Preferably, the N is 16,64 or 128.
Beneficial effect：The present invention is by changing lines, assignment " 1 " at profile, assignment " 0 " in profile, only contrasts at profile
Similarity；It is bigger to solve the matrix quantity of division, contrasts gray value one by one, amount of calculation is huge, expends the time and more asks
Topic.

Embodiment
Embodiment：M, N value are 4 by the present embodiment, are comprised the following steps：
Such as Fig. 1 and Fig. 2, the first step：Source picture is divided into 4 4*4 matrixes, in order mark 1,2,3 ... ... 4.
Such as Fig. 1 and Fig. 2, second step：Contrast picture is divided into 4 4*4 matrixes, in order mark 1 ', 2 ', 3 ' ... ... 4 '.
3rd step：By source picture, the element for all 4*4 matrixes for contrasting picture, according to gray scale assignment, from low to high successively
3 for 0,1 ...；Wherein, 0 white is represented；3 represent black.
Such as Fig. 3, the 4th step：By the outer rim line of the matrix element of same grayscale value, and " 1 " is entered as again, in line
The matrix element of all same grayscale values in portion is entered as " 0 " again, only contrasts in source picture and contrast picture, is entered as " 1 " position
The assignment put, obtain the similar proportion of each contrast；100% is 114, and 0% is 3；
5th step：The similar proportion obtained according to the 4th step, source picture is calculated with contrasting the similarity of picture；114/
(114+3)=97.43%.
Claims (3)
1. a kind of similar decision method of picture based on conversion lines, it is characterised in that comprise the following steps：
The first step：Source picture is divided into M N*N matrix, in order mark 1,2,3 ... ... M；
Second step：Contrast picture is divided into M N*N matrix, in order mark 1 ', 2 ', 3 ' ... ... M '；
3rd step：By source picture, the element for all N*N matrixes for contrasting picture, according to gray scale assignment, 0 is followed successively by from low to high,
1……N-1；Wherein, 0 white is represented；N-1 represents black；
4th step：By the outer rim line of the matrix element of same grayscale value, and " 1 " is entered as again, it is all identical inside line
The matrix element of gray value is entered as " 0 " again, only contrasts in source picture and contrast picture, is entered as the assignment of " 1 " position, obtains
