Description
Technical field
The present embodiments relate to technical field of image information processing, and in particular to a kind of image is internally embedded machine sensible information
Method and system.
Background technique
During the rapid development of information technology, information collection and acquisition of information problem be information technology research and development always with
Key problem in application process.Currently, one kind is to pass through image pickup there are two types of information automation acquisition major ways
The mode of the heat transfer agents such as head, Temperature Humidity Sensor, microphone acquisition, converts the signal in sensing equipment information collection region to
Data information, and be further processed in such a way that pattern recognition and classification extracts feature and be converted into information system
The valuable information that can be utilized.For example by common camera etc., the scene that license plate carries out automatic identification is clapped, actually
It is after Image Acquisition is returned system, directly handling image and carrying out OCR identification (is substantially that image segmentation and classification isotype are known
Processing is not carried out) and extracts license plate number information, and characteristic information is obtained by so-called intelligent device, carries out relevant Information procession,
Processing is all similar process.
Another kind is by Automatic Identification & Data Collections such as bar code, two dimensional code, RFID, the characteristics of this kind of technology
It is to obtain the storage in standardized data carrier by devices such as the image collecting devices such as camera, radio frequency identification interrogators
Information, to directly carry out information processing or processing.Bar code, two dimensional code, RFID are a kind of data mediums for carrying information, for
For two dimensional code, substantially two dimensional code is a kind of image code carrier, can be by coded image also by the reading method of standard
It originally was original information.
From the point of view of state-of-the-art, most widely used at present, the type collection technology of distribution most extensively, the most mature is
Image information collecting technology, the mobile phone in current industry camera, traffic camera and public hand, early have become acquisition and
Handle the most important information terminal of information.And using bar code, two dimensional code as the automatic identification technology of representative, serve the logistics in the whole world
Commerce and trade already exceed 40 years, by taking the bar code on commodity as an example, by acquisition bar code information complete commodity clearing, make an inventory and
Retrospect etc. is the prevailing model of commodity retail.
In recent years, planar bar code technology becomes the skills such as automatic identification technology and commodity sign, mobile marketing and product back-tracing
The most important hot spot technology of art and application development.Planar bar code technology, especially using Chinese letter co, QR code as the matrix type two-dimension of representative
Code, essence are a kind of special structured graphics, which has macroscopic view by the two dimensional code and other two dimensional codes to be distinguished
It the characteristic graphics frame of feature and is distributed in graphics frame, the data with specific information arrangement mode and coding definition
Sequence of modules or group are combined into.The data acquisition modes of two dimensional code are the image collecting devices such as camera, are adopted by analysis processing
Collect the image obtained, find the pattern image of two dimensional code in the picture, to detect picture position, the orientation etc. for obtaining two dimensional code
Essential information, and then out of, two dimensional code graphics frame, using information arrangement mode defined in two dimensional code standard, obtain two dimension
Information coding matrix in code.
As the extensive use of two dimensional code, especially two dimensional code are direct in the classes such as commodity, mobile marketing, advertisement and consumer
Correlation can directly acquire the fast-ripenin and large-scale application of the application model of the New Two Dimensional code technology of information by network,
In traditional two dimensional code, increase figure, color etc., to change the human eye vision effect of two dimensional code, makes two dimensional code and packaging
Or the scheme that combines together of graphic designs has begun and propagates its belief on a large scale, and has certain entangle in particular with planar bar code technology itself
Wrong function, the superposed graph LoGo in image in 2 D code, or change functional graphic shape or data module in image in 2 D code
Shape, the application for increasing two dimensional code by aesthetic feeling of the design are very common.However, these technical solutions are the problem of can't steer clear of:
The first, these schemes (are entangled with only the graphical information redundancy (functional graphic) and information redundancy of two dimensional code
It is wrong), it is still the package design member such as LoGo of the technical solution in traditional planar bar code technology frame, two dimensional code and commodity or product
Element or pictorial element are still separation, cannot be known as integrated.
The second, these existing technical solutions are all the recognition performance (software types that can be distinguished to reduce two dimensional code
Limited, software distinguishes average speed is slow, environmental requirement improves etc.) it is cost, if excessively considering graphical visual effect, no
The evitable two dimensional code that will cause is difficult to distinguish.It is because while to have beautified two dimensional code, but is actually to be folded on two dimensional code
Add the noise of figure, the recognition performance decline of these two dimensional codes is very big.
On the other hand from the point of view of, current image pattern recognition achieves development at full speed, with deep neural network
The maturation and chip of technology software and hardware, the equipment with image steganalysis function, the especially personal mobile communications such as mobile phone
Equipment has been increasingly becoming mainstream, original graphic pattern discrimination extracted by the realtime graphic identification to denounce and graphic feature and
Processing problem is gradually resolved, and also has become current development in image recognition and the intelligent image processing of mobile terminal
One of mainstream commercial trends.
However, the intelligent image identification technology of existing mobile terminal is faced with following challenge:
The first, the intelligent image identification technology of existing mobile terminal substantially belongs to the model of pattern recognition and classification technology
Farmland determines the characteristic value of identification object (actually image pattern) by modes such as deep learnings, and provides most probable knowledge
Other classification results.Due to the real-time in mobile terminal and the limitation of storage resource is calculated, relevant classification calculating and characteristic value mention
It takes and is all more limited, to mean that relevant pattern-recognition accuracy and efficiency are more limited, be easy to appear mistake.
The second, the intelligent image identification technology of existing mobile terminal can only extract the characteristic of division information of image,
The fingerprint feature information of image can only be obtained using deep neural network technology on the basis of training set, even if using same
Belong to the OCR technique of mode identification technology, the error rate of the text information of acquisition is still higher, therefore for needing to carry out precisely individual
The occasion of identification is still not applicable.
To sum up, it needs a kind of new to be internally embedded the technical solution of machine sensible information in image.
