The image feature of works genuine piece, obtain and/or works to be demonstrate,proved described in showing with the described described works genuine piece for identifying
The corresponding some images of image feature are waited to demonstrate,prove, and this two group images feature are compared, and find analyzing through comparison
Image feature inconsistent with the image feature of the works genuine piece prestored in described works to be demonstrate,proved, analyzes and judges whether to belong to works
The change of genuine piece.
Described image feature can with use arbitrarily be suitable to comparison analyze form, generally can use following any one or
Various ways:
A () identifies all images in region and/or the parts of images in qualification region；
B () identifies the whole and/or composition of parts of images in region；
C () identifies the partial pattern in the image in region or the element of described partial pattern；
D () identifies the characteristic parameter of the element of the partial pattern in the image in region and/or described partial pattern；
E () identifies the distance parameter between the specified point in the work images in region and/or location parameter；
F () identifies that the cognizable canvas pattern in region and/or material feature are (for the facility in statement, institute of the present invention
State painting canvas and refer to the base material of works, include but not limited to usually said painting canvas).
Described qualification region can be to use the form that arbitrarily can define and can comprise image feature, typically
Any one region following or any multiple region: the some region of zero dimension, one-dimensional line region and the region, face of two dimension.
The storage mode of the image feature data of described works genuine piece can be that material object stores and/or electronic data is deposited
Storage.
In order to be more convenient for implementing, it is preferable that quick recognition template can be used (to be referred to as identification plate or fidelity is identified
Plate) determine and identify the qualification region of described works, described quick recognition template is that its plate face is provided with several identifying holes (also
Can be described as identify hole) flat board, described identifying hole is the isometrical through hole being perpendicular to plate face, will described quick recognition template according to select
Fixed covering position covers on described works genuine piece, on the works picture exposed after covering selected following any one or many
Planting zonule is described qualification region:
A whole region that () reveals from described identifying hole, this region is defined by this identifying hole and is identified；
B () is positioned at around described quick recognition template and can be by it relative to the seat at described quick recognition template edge
Demarcate and determine and the region of identification；
C () is positioned at described identifying hole and can be defined by it relative to the coordinate at described identifying hole edge and identify
Regional area.
Generally, described quick recognition template covering position on described works can be selected according to the feature of works, to protect
Identifying in region that card select comprises the image feature being suitable for qualification, generally, it is preferred to discernible with on described works
Point and/or line as described quick recognition template location identify, with guarantee described quick recognition template cover cover at selected
On lid position.
Usual described quick recognition template covers the mode of works: again by described quick knowledge after the described works that tile
Other template is laid on the surface of works.
Described quick recognition template covers the mode of works: described quick recognition template and works are hung down respectively
Directly hang up, described quick recognition template is blocked before described works, not only realizes by the way of hanging is blocked
Coverage effect to works, but also can avoid because quick recognition template is pressed on works the infringement causing works.
Beneficial effects of the present invention: by the present invention, as long as author once carried out fidelity to painting and calligraphy pieces identifies archive,
(can be described as works to be demonstrate,proved) when doubtful works occur and need to carry out authenticity, can extract and archives in doubtful works
(quantity of the image feature owing to using when identifying can be equal to the corresponding image feature of the image feature data of middle preservation
Can also be less than the image feature of the works genuine piece prestored, therefore, the present invention uses " for identify " to limit when necessary
Image feature actually used during qualification), then compare with the corresponding information in archives, as long as there being at one image feature not
With, then can immediately arrive at doubtful works is to copy the conclusion of works (unless this difference is because genuine piece change and causes, such as,
Painting canvas pollution, variable color and breakage etc.), as the most identical in all of image feature comparison, then can assert that these doubtful works are genuine piece, right
The image preserved in marked feature with archives has the doubtful works being clearly distinguished from, it might even be possible to realize the mesh of " at a glance determining the true and false "
, it is to avoid in the qualification process of conventional painting and calligraphy pieces and plane art as with unlike, like with not like on often occur striving
Opinion problem endlessly.
What the complicated image characteristics of painting and calligraphy pieces and plane art was reduced to that system essence wants by the present invention is prone to judge
With image feature or its data message of statement, reach the purpose simply and rapidly doubtful works identified, and identified
Result precisely, there is scientific basis, this invention simplifies the qualification step that painting and calligraphy pieces and plane art under prior art are loaded down with trivial details
Suddenly, reduce the workload of appraisal, decrease the working time needed for qualification, improve work efficiency.
Owing to the present invention can also use same or identical quick recognition template to make with waiting to demonstrate,prove at painting and calligraphy pieces genuine piece
Product are chosen corresponding region, not only facilitates the selection identifying region, and owing to the position between each qualification region is closed
System is limited by quick recognition template, as long as finding the covering position of quick recognition template during qualification accurately, ensures that qualification region is
Identical, identify that the feature in region and the position relationship between feature and reference point are also identical, and in reality
Comparison work in, the comparison result of works to be demonstrate,proved shows deviation, even owing to fakement is in the size of other parts
Difference occur, the work images also resulted in some qualification regions offsets, the most then can directly determine that works to be demonstrate,proved are
Imitated works.Quickly using of recognition template is conducive in two width works corresponding region and the selection of feature and determines have
It is beneficial to the Rapid Implementation of appraisal.
Accompanying drawing explanation
Fig. 1 is the flow chart of the present invention.
Detailed description of the invention
Seeing Fig. 1, the authentication method of the present invention is substantially to select the subregion in works to compare, to replace
For the comparison analysis of the whole picture of works, thus not only reduce workload, improve the work efficiency of qualification, but also permissible
Find for the image feature identified relative to the change (change on entire picture in other words) of position easily, make qualification more
For accurately.
Owing to, for a width painting and calligraphy pieces or plane art, (such as the identifying region) image on specific region is
Uniquely, therefore when comparing, as long as having the image in a qualification region or other image features to differ, the most permissible
Assert that works to be demonstrate,proved are not genuine piece (imitated works, fakements etc.), unless these differences are through analyzing the change belonging to genuine piece, if treated
Area image feature area image feature corresponding with archives in card works is the most identical, then assert that works to be demonstrate,proved are genuine piece.
The image in described qualification region can be the painting and calligraphy pieces all images in qualification region, it is also possible to be to identify region
Interior topography, can be the image through different multiples processing and amplifying, it is also possible to be the non-enlarged drawing obtained of normally taking pictures
Picture, described image generally can use image capture device (such as digital camera) to obtain from corresponding works, described local
Image preferably has the topography of distinguishing feature.
Described image feature can include the position relationship between each topography, and (each topography as selected is mutual
Distance), position relationship between each marked feature in overall or topography (as between certain two object of drawing in paintings away from
Distance between certain two word, certain unicursal of some word in distance between, some objects head and the tail or calligraphy work
Distance between Shou Wei), position relationship between each marked feature and reference point set in advance (sets in advance in overall or topography
Fixed reference point is one or several fixing points selected in works), characteristic image in overall or topography (has
The significantly image of recognition effect), characteristic pattern (pattern included in image) etc., it might even be possible to be between some reference points
Position relationship, the ink marks of picture can be included, colour and be left white, it is also possible to be flaw intrinsic on painting canvas and texture etc..
Preferably, in carry the painting and calligraphy pieces doing works source fidelity from author, extract the image feature in qualification region
Time, extract representative image feature as much as possible and be stored in genuine piece image feature data base, so that follow-up to doubting
Like in the qualification process of works, archives have sufficient amount of can the image feature of comparison for reference, to ensure what fidelity was identified
Accuracy and science, and for identifying the selection in region, make these regions contain the figure with evident characteristic the most as far as possible
Picture, in order to extracting the image feature being prone to identify and identify, certainly, in order to be better protected from forging, some of picture is trickle
Difference (difference that just can show under the most micro-effect) also is used as the image feature of genuine piece and is stored in data base, these
Identify region and the selection of image feature, can determine according to works feature and qualification requirement.
Preferably, when carrying out described comparison and analyzing, following manner can be used: first based on general image and/or whole
Marked feature or image characteristics in body image are compared, then based on the marked feature in topography and/or topography
Or image characteristics compares.The purpose using this comparison principle is to, in the qualification process to doubtful works, subtract as far as possible
The workload of few appraisal, the element, marked feature and/or the image characteristics that comprise due to general image are compared to topography
The element, marked feature and/or the image characteristics that comprise are many and obvious, are easy to observe and compare in comparison process, as long as finding
Difference at one, can draw the conclusion that doubtful works are imitated works, it is not necessary to compare topography, even play a game
Portion's image is amplified processing, and when the comparison of general image is not enough to draw expert's conclusion, then carries out topography accordingly
Process and comparison.
In practice, generally can use following workflow:
1, author's (or other applications of having the right identify other people that achieve, lower with) takes and carries out paintings source guarantor for works
Very, and the standby examination later of reserved personal information.
2, paintings are carried out overall shooting after initial survey confirms, with quick recognition template, paintings are carried out positioning fidelity and clap
Take the photograph.The paintings personal characteristics of shooting, collecting is segmented further, preserves image data.
3, each category feature carried out comprehensive test and draw a conclusion, providing fidelity certificate for author afterwards, and by paintings data
Make archive.
4, works return when identifying while identifying (treat card works), quickly identify mould according to raw file with identical
Paintings are positioned by plate again, and navigation data and raw file data carry out intersecting comparison, for ensureing author's rights and interests, identify
Generally should be proposed by author or agree to through author.
For identifying that claimant provides testimonial, and the second time materials of identification are together filed with raw file data.
