Description
Technical field
The invention belongs to image processing field, more particularly to a kind of processing method and system of high quality picture.
Background technology
With the development of image processing techniques, the work such as the editor of picture, typesetting can be automatic by computer software
Complete.Such processing software has a lot, and its function is different.For example, this area it is common powerful picture processing it is soft
Part Photoshop, abbreviation PS, its powerful editor and processing function disclosure satisfy that various editor's needs of picture, and can
Preferably keep picture quality.
However, for most people, such as PS etc photo handling software still falls within professional software, its function is numerous
It is more, also need to all kinds of parameters of skilled setting comprising a large amount of feature cards, and in actual editing process, its technical threshold compared with
It is high；In addition, PS etc software belongs to charging software in itself, while installs the larger disk space of software needs, it is not easy to
Large-scale promotion uses in general population.
In face of this problem, the photo handling software for being more easy to introduction or APP of various miniaturizations arise at the historic moment.These are soft
Part or APP generally only have several million sizes, and operating function is simple, can realize foolproof picture processing, such as key beautification/
Add word.Wherein, most known is exactly that U.S. figure is elegant.The software does not only have computerized version sheet, also mobile phone version, more has
Notably, webpage version is have also been developed at present so that the threshold of picture processing substantially reduces.
However, the photo handling software or APP of such miniaturization are although easy to use, but it is actually to sacrifice figure
Tablet quality is cost.For example, the source picture of more than ten M ultrahigh resolution, after U.S. figure show beautifulization of webpage version,
Picture size generally only hundreds of KB are exported, high quality output are selected in processing procedure, output picture size is at most only
There are several M more, greatly reduce the quality of source picture.But for some important events, the matter of the picture after guarantee processing
Amount is highly important；In addition, source picture number is numerous caused by these occasions, also should not be one by one using the picture processing of specialty
Software（Such as PS）Handled.
Therefore, urgent need is a kind of can keep picture quality and be suitable for the method for handling extensive picture, and can
Promoted the use of under relatively low technical threshold.
The content of the invention
To solve the above problems, the invention provides a kind of image processing method, this method can quickly introduce big spirogram
Piece is simultaneously handled picture accordingly, while ensures picture quality.
In the present invention, ensure picture quality it is to be understood that picture before treatment after size be held essentially constant；Example
Such as, pixel it is constant/resolution ratio is constant etc..
As a concrete implementation scheme, picture processing of the invention refers to carry out at word in pending picture
Reason, for example, adding corresponding word.
In the first aspect, the image processing method is realized by browser by webpage, is comprised the following steps：
Picture steps for importing：Webpage is opened by browser, loads pending picture.
The present invention loads pending picture by webpage connector, avoids special software installation process, while use net
The form of page plug-in unit is easy-to-understand, is more beneficial for ordinary people and receives and use.
In the present invention, pending picture is loaded by webpage connector, various ways can be used.If it is determined that user
Browser version is supported to open picture, then directly using the corresponding picture of browser loading；
Otherwise, then search user can locally open the corresponding processing program of the picture, for example, windows Photo Viewers,
The drawing software carried in windows annexes, or other picture processing programs that user may install, pass through the picture
Processing routine opens pending picture, and is automatically loaded into the Webpage of browser and shows.
It is pointed out that in this step, only loading pending picture, any place is not carried out to picture
Reason, therefore, any change will not occur for the quality of picture.
Picture processing region selection step：Select to carry out the part of word processing in pending picture.
Under normal circumstances, some specific regions need to carry out word processing in pending picture.These specific regions
It is that user can be selected by corresponding selection operation, for example, carrying out frame choosing, stroke choosing by mouse, touch-screen etc., enclosing and select
Deng the picture processing region selection step being performed, so as to select the part that word processing is carried out in pending picture.
Picture processing regioinvertions step：The part of word processing will be carried out in the pending picture selected
Picture is converted into polar plot.
In this step, it is necessary to which the picture of processing is only the picture block of some or some specific regions, specifically,
It is some or some subregions of the pending picture that carry out word processing for handling user's selection.
Concrete processing procedure is exactly that the picture block of some or some subregions by this is converted into polar plot.
In practical matter, pending picture is not largely polar plot, but common bitmap.Existing picture
Processing method is also handled in itself both for bitmap.Zone bitmap is converted into region polar plot by the invention,
So as to ensure that picture quality lays the foundation for follow-up word processing.
Common bitmap is converted into polar plot, the existing a variety of common instruments in this area.For example, mentioned in background technology
PS is the bitmap of exportable .eps forms；In addition, VECTOR MAGIC softwares, which are also typical bitmap, turns one of polar plot instrument.
Word vector figure generation step：The word generation word vector figure that will be added in picture.
In traditional image processing method, word is added in picture, is typically to be inserted directly into word.In this process
In, the picture block in the region substantially to inserting word is edited so that word turns into a part for picture or covered
The original region of lid picture.In pixel scale, word and picture do not correspond to, and will lose picture quality during so as to insert word.
In the present invention, word is no longer inserted directly into, but firstly generates word vector figure.For Chinese text
Speech, it is substantially that geometry is realized.With reference to polar plot feature, the present invention proposes the concept of word vector figure.
It is well known that the image or Drawing image of polar plot, also referred to as object-oriented, be mathematically defined as it is a series of by
The point of line connection.Graphic element in vector file is referred to as object.Each object is an entity having a style of one's own, and it has
The attributes such as color, shape, profile, size and screen position.Polar plot is can be come graphing, vector according to geometrical property
One point or a line, polar plot can only lean on Software Create, and file occupancy internal space is smaller, because such image is literary
Part includes independent separate picture, freely unconfined can reconfigure.Its feature be amplification after image will not distortion, and
Resolution ratio is unrelated, suitable for graphic designs, word design and some Mark Designings, Layout Design etc..
Therefore, the step for of the invention enables to the word of generation, and picture is still protected after being inserted into picture
Hold higher quality.
Character area synthesis step：The picture block of word vector figure and foregoing some or some subregions is transformed
Polar plot synthesis.
Because the picture for the part that carry out word processing in foregoing pending picture has been converted into polar plot, to insert
Word also have been converted into word vector figure in itself.In this step, it is necessary to which this two parts polar plot is synthesized, so as to
Form the picture of added word.
When noticeable, because polar plot is substantially that a series of points by line connection form, two polar plots merge
When can be by the preferable uniformity of the realization such as its corresponding vector point/line, without bringing mass loss；Its merging process is real
It is mathematically the corresponding coincidence of dotted line, relative position adjustment, the change of geometry projection etc. in matter, will not more brings the deformation of image.Close
Picture after and can remain polar plot.
Preferably the polar plot after merging can be converted into bitmap as one, then by the bitmap and original pending figure
The other parts combination of piece, so as to form the picture after final processing.
It is, of course, also possible to after being synthesized in above-mentioned synthesis step to two polar plots, bitmap is directly output as, then
The other parts of the bitmap and original pending picture are combined, so as to form the picture after final processing.
It is important to note that it is not that a bitmap is converted into polar plot to be handled it is ensured that its matter
Amount.In fact, in most cases, bitmap is converted directly into polar plot can lose more information on the contrary.Polar plot is only fitted
Share to show simple lines and figure, if the photo of performance personage's landscape is converted into polar plot, that just can only
It is the appearance as Freehandhand-drawing.
Therefore, in the present invention, it is to carry out vector quantization for pending region unit, these region units are to need to add text
The region of word, it is usually expressed as, and amount of color is few, and color lump is big, therefore is just adapted to carry out vector quantization, this hair on the premise of fidelity
A person of good sense is exactly to be found that this point just proposes improved image processing method；It is most important to be, at word
Manage region and corresponding word adding procedure；Because word is in itself as polar plot, its show and simple lines and
Figure.
Thus, in second aspect, the present invention provides a kind of more general image processing method, including：
（1）Picture load step：Load pending picture and show；
（2）Character area selects step：Selection will add the region of word in the pending picture, as pending picture

（4）Word vector figure generation step：The word generation word vector figure that will be added in the pending picture；
（5）Word picture block generation step：The polar plot tile and the word vector figure are synthesized into word picture block.
At the 3rd aspect, image processing method of the present invention can use computer system to realize that the system can
So that including corresponding computer-readable recording medium, the executable finger of corresponding computer machine is performed by processor and memory
Order, so as to realize affiliated image processing method.
