Detailed description of the invention
Referring to Fig. 1, the invention provides a kind of painting and calligraphy pieces fidelity identification systems, its authentication method comprises the following steps:
(1) trying to figure out the style entertaining of works, artistic conception mental state with the eye observation of appreciation of arts, combine with the rhythm that a composition, the skill art of composition and color are linear, therefrom observation analysis goes out habitual feature stable when author creates, rule;
(2) from works genuine piece, observation analysis goes out the morphological characteristic writing freely and easily in strokes and dots and moulding composition to materials such as pen and ink, greasepaint, pigment at works in works genuine piece and the morphological characteristic with the interrelated intention such as the chi width of works, form, the technique of writing, charm and/or style, note finding gathering reflection author's style, power, skill, artistic pursuit or other people be difficult to the personal characteristics that replicates, pay special attention to observe artificial set retouch, air brushing, watermark, take off mount, mend by replacing a damaged part, the anomalism such as adulterium;
(3) for works genuine piece calligraphy, topic note, preface and postscript, inscription, the person's handwritings such as printed text, trace etc., observation analysis goes out author expresses in the technique of writing, knot word processing, in art of composition scheduling processes, with pen, take gesture, in pursuit process from however careless in the writing style feature that reflects and corresponding literary style, the order of strokes observed in calligraphy, wield the pen, the minutias such as blend proportion and/or a receipts anaphora relation, and layout, the word style and features feature such as the art of composition and/or idiom, detection seal, personal details feature in printed text and personal print mud feature, note inscription time and paper using simultaneously, with ink, with or without space-time on materials, contradiction in logic is with unusual, word and between drawing with or without the anomalism such as inconsistent in style and features level,
(4) from works genuine piece, observation analysis goes out the paper using of works genuine piece, with the material feature such as cloth and/or materials and paper, the stricture of vagina reason that the materials such as cloth self are intrinsic, stalk slag, fault, fiber, jackknifing, the tiny characteristics such as defect and/or spot, can by different light sources, light wave and micro-, moisture-inhibiting, the technological means such as amplification carry out the thin survey of essence inspection, and utilize the physical form of their own and the color of works, ink, color, pile up, dizzy scattered, withered pen, the juxtaposition of the phenomenons such as the style of calligraphy characterized by hollow strokes and form " pen and ink birthmark " and " paintings gene " etc. and can reflect the system features of works uniqueness,
(5) by any one in features described above, several or entirely as identification mark, shoot the image identifying region at described identification mark place, and obtain the image feature data of works genuine piece accordingly, storage forms news file, and the storage mode of described image feature data can be storage (film storage) in kind and/or electronic data storage (digital storage);
(6) image feature being used for identifying in each described qualification region treating card works is compared to the corresponding works genuine piece prestored corresponding image feature in each described qualification region, and in this, as judging to treat the foundation of the card works true and false, for treating that assay certificate provided by card works.
The authentication method of the present invention is substantially select the subregion in works to compare, to substitute the comparison analysis of the whole picture of works, thus not only reduce workload, improve the work efficiency of qualification, but also the change (in other words the change on entire picture) of image feature relative position for identifying can be found easily, make qualification more accurate.
Due to for width painting and calligraphy pieces or a plane art, (such as identifying region) image on specific region is unique, when therefore comparing in described step (6), if described in treat completely the same for corresponding image feature in each described qualification region of the image feature identified and the works genuine piece prestored in each described qualification region of card works, it is judged that this waits that demonstrate,proving works is genuine piece; If described in treat not quite identical for corresponding image feature in each described qualification region of the image feature identified and the works genuine piece prestored in each described qualification region of card works and think that described inconsistent image feature all belongs to the change of works genuine piece by analysis, it is judged that this waits that demonstrate,proving works is genuine piece;If described in treat not quite identical for corresponding image feature in each described qualification region of the image feature identified and the works genuine piece prestored in each described qualification region of card works and by analysis described inconsistent image feature do not all belong to the change of works genuine piece, it is judged that treat that card works are not genuine piece (copying works, fakement etc.).
Described identify that region can be the region, face of the some region of zero dimension, one-dimensional line region and/or two dimension.
Described image feature can adopt following any one, several or whole form:
All images in (a) described qualification region and/or parts of images;
The composition of the whole and/or parts of images in (b) described qualification region;
The partial pattern in image in (c) described qualification region or the element of partial pattern;
The partial pattern in image in (d) described qualification region and/or the characteristic parameter of the element of partial pattern;
The distance parameter between the specified point in image in (e) described qualification region and/or location parameter;
Cognizable canvas pattern in (f) described qualification region and/or material feature.
Described image feature can be the image through different multiples processing and amplifying, it can also be the non-enlarged drawing picture obtained of normally taking pictures, described image generally can adopt image capture device (such as digital camera) to obtain from corresponding works, and described topography preferably has the topography of distinguishing feature.
Described image feature can include the position relationship (distance as mutual in selected each topography) between each topography, (certain drawing in the paintings even distance between object of position relationship between each marked feature in overall or topography, distance between some objects head and the tail or distance between certain two word in calligraphy work, distance between certain unicursal head and the tail of some word), position relationship between each marked feature and reference point set in advance in overall or topography (reference point set in advance be one or several fixing points) selected in works, characteristic image (there is the image of obvious recognition effect) in entirety or topography, characteristic pattern (pattern comprised in image) etc., can even is that the position relationship between some reference points, the ink marks of picture can be included, painted and be left white, can also be flaw intrinsic on painting canvas and texture etc.
Preferably, when carrying the image feature extracting qualification region in the painting and calligraphy pieces doing works source fidelity from author, extract representative image feature as much as possible and be stored in genuine piece image feature data base, so that in the follow-up qualification process to doubtful works, archives have sufficient amount of can the image feature of comparison for reference, to ensure accuracy and the science that fidelity identifies, and for identifying the selection in region, these regions are then made to contain the image with evident characteristic as far as possible, so that extracting the image feature being prone to identify and identify, certainly, in order to be better protected from forging, some technicality (or even the difference that just can show under micro-effect) of picture also is used as the image feature of genuine piece and is stored in data base, these identify the selection of region and image feature, can determine according to works feature and qualification requirement.
Preferably, when comparing, it is possible to adopt following manner: first compare based on the marked feature in general image and/or general image or image characteristics, then compare based on the marked feature in topography and/or topography or image characteristics.Adopt this comparison principle in order that in the qualification process to doubtful works, reduce the workload identifying work as far as possible, due to the element that general image comprises, the element that marked feature and/or image characteristics comprise compared to topography, marked feature and/or image characteristics are many and obvious, comparison process is easy to observe and compare, as long as finding a place different (being not belonging to the change of works genuine piece), the conclusion that doubtful works are imitated works can be drawn, again topography need not be compared, even it is amplified topography processing, when the comparison of general image is not enough to draw expert's conclusion, topography is carried out respective handling and comparison again.
Referring to Fig. 2, in practice, identify that work generally can adopt following workflow:
(1) early-stage preparations: being familiar with style characteristic and the related data of works genuine piece, handle corresponding entries, check the equipment equipment;
(2) check mark first trial: observe and make quality, specification, understands works basic condition, notices that observing works has without exception, and registration in time is filled in a form and handled corresponding commissioned procedures, extracts word and/or the seal sample material of author simultaneously;
(3) space-time is fixed: shooting works genuine piece source fidelity image data, including the works genuine piece overall picture photo of high-resolution;
(4) dialysis is observed: fully have thorough grasp paintings feature, fully understand the characteristic information that paintings are provided by pen and ink, pigment, skill and technique and the material such as paper, cloth, put the personal characteristics of heterogeneity, dissimilar, different levels in order, stealth characteristics that may be present is studied and judged in analysis, forms and deepen the penetrating and correct judgement of oneself;
(5) detection gathers: gather the image in described qualification region according to described authentication method, forms news file;
(6) final conclusion factually: according to news file, according to " macroscopic view lift want, microcosmic exposition, feature are advocated, substantial evidence final conclusion " principle treat card works and carry out fidelity qualification, and provide documented evidence foundation.
Above-mentioned " macroscopic view lift want, microcosmic exposition, feature are advocated, substantial evidence final conclusion " in " macroscopic view lift will " refer to form linear features such as composition color complicated and diversified on painting and calligraphy pieces, skill and technique, charm, style kinds, by checking, summarizing, comprehensively, selected refinement is to several centrostigmas that can describe the problem, gather typical characteristic, in the way of shape letter meaning is complete, crucial critical position, directly inform and display, also can be very clear even if making to be ignorant of skilled person. This turn difficult into easy, simplify, a bit with regard to saturating way, both provided convenience for client's check of genuineness, also simplify exhaustive detection analysis process. Being effectively improved technical work matter effect, the image identified for fidelity contrasts a kind of method providing more fast accurate.
" microcosmic exposition " refers to utilization modern science and technology, and depth is pushed in the space identifying inspection. It is exactly utilize works self just to have microscopic species characteristic from outward appearance to inner essence to disclose the uniqueness substitutive characteristics in works. Specifically use special light sources light wave exactly, by the specialty measure such as micro-, perspective, amplification, " pen and ink birthmark " and " material gene " detection being born with in paintings sky uses, maneuver by " the falling of one leaf heralds the autumn ", wherein most checking the uniqueness characteristic of value to be fixed within less " window ", and disclose out with the mark picture accurately measured, high definition is amplified. There is provided high-quality and efficient direct basis for expert's conclusion, differentiate to provide visual and clear comparison to prove for the circulation that works are later.
The relatively large identifying hole of identification plate is used time " macroscopic view is lifted and wanted ", play the effect of " art feature ", using the less identifying hole of identification plate time " microcosmic exposition ", receive the merit that the gate of vitality attacks a vital point, different size of identifying hole is with the use of tackling various uncertain factor at random.
" feature opinion " refers to that all are identified and advocates reliable and stable image characteristics all to be used to show to support with qualification result, show the intrinsic propesties of things with directly brief image characteristics, show the accurate science of assay by the data of objective reality.
