Abstract
The invention relates to a method for generating and applying a digital image watermarking technology, which is characterized by comprising the steps that 101, an information processing unit carries out decoding on an image and calculates a two-dimensional entropy value P by using a formula, a certain pixel of the image is selected, a gray average value of pixels around the pixel serves as a comprehensive feature of gray distribution, and a feature 2-tuple set is formed; 102, an information processing unit converts a website or a commodity mark into a binary code; 103, the information processing unit embeds the binary code into the image, the binary code can be embedded into one or more areas of the image according to the size of the two-dimensional entropy value, and an image code is formed; 104, a user downloads the image code and manufactures the image code into an advertisement of various media or a commodity package; and 105, an intelligent terminal device carries out processing on the advertisement or commodity package in which the image code is embedded. According to the invention, the digital watermarking technology based image code, which is invisible to the human eyes, is utilized to replace a two-dimensional code or a barcode, thereby improving the user experience and improving the efficiency of a POS machine.
Description
Technical field
The present invention relates to computer image processing technology field, especially relate to a kind of digital image watermarking technology
Generate and the method for application.
Background technology
Popularizing of adjoint mobile Internet, mobile terminal and smart mobile phone, utilizes Quick Response Code or bar code to represent net
Location URL is becoming increasingly popular, and that it facilitates cellphone subscriber and accesses relevant network address.
But the shortcoming of Quick Response Code is the most clearly, such as, in the case of the space of a whole page is limited, Quick Response Code itself account for
The biggest region, if user still wants to show other advertising messages, such as LOGO or other images, Zhi Nengfang
In the region that Quick Response Code center is the least, the effect of publicity is undesirable.
It addition, popularizing along with POS, bar code has obtained promoting widely, but it is often only at product bag
Load onto appearance once, POS often the most just can complete the operation of scanning, and sometimes during scanning
Owing to the position at bar code place is bad, often scanning less than, cause unnecessary delay, affect the shopping of consumer
Experience.
Summary of the invention

101, image is decoded by information process unit, and calculates the two-dimentional entropy of this image by below equation
P:
Select certain pixel of image, using the gray average of this pixel surrounding pixel as the comprehensive characteristics of intensity profile,
Composition characteristic two tuple, be designated as (i, j), wherein i represents the gray value (0 ＜=i ＜=255) of pixel, j represent neighborhood ash
Degree average (0 ＜=j ＜=255), the width of image is W, and height is H:
Pij=f (i, j)/W × H
Above formula can react the comprehensive characteristics of gray value on certain location of pixels and the distribution of pixel grey scale about, wherein f (i,
J) be characterized two tuples (i, frequency j) occurred, defining discrete two-dimensional image entropy Q is:
Q=-∑ ∑ (PijlogPij)
If above-mentioned entropy cannot embed network address URL or commodity mark less than the threshold value preset, prompting this image of user
Knowing, flow process terminates；Otherwise, 102 are performed.
102, information process unit is transformed into binary code network address or commodity sign.
103, above-mentioned binary code is embedded in above-mentioned image by information process unit, according to the two-dimentional entropy of image
The above-mentioned binary code of size can form an image code with one or more regions of embedded images.
104, businessman downloads above-mentioned image code, and is made into the advertisement of various media or the packaging of commodity.
105, advertisement or the commodity packaging of embedded images code are processed by consumer's intelligent terminal.
Described step 102 information process unit is transformed into binary code, commodity sign bag network address or commodity sign
Include the goods number represented by commodity bar code；
Described step 104 businessman downloads above-mentioned image code, and is made into the advertisement of various media or commodity
Packaging, specifically includes following steps:
If what 301 digital watermarkings represented is network address, perform 302；If what digital watermarking represented is commodity sign,
Perform 303.
302, the image making embedding above-mentioned digital watermarking is become the advertisement of books and periodicals, magazine, TV, or webpage.
Termination process.
303, the image printing embedding above-mentioned digital watermarking is become the outer package of commodity, is entered by intermediate links each
Plant market and supermarket.
Described step 105 consumer intelligent terminal to the advertisement of embedded images code or commodity packaging at
Reason, specifically includes following steps:
401, consumer's intelligent terminal scanogram code having filled above-mentioned digital watermarking decoding program, letter
This image code is resolved by breath processing unit.
402, if it find that complete digital watermarking, perform 303.Otherwise, prompting user rescans or middle fluid stopping
Journey.
403, digital watermarking is decoded, if obtain is network address URL, performs 304；On if
State that digital watermarking represents is a commodity sign, performs 305.
404, this network address of browser access of intelligent terminal, termination process are called.
405, intelligent terminal shows the trade name of these commodity, pricing information or be directly entered charging system, terminates stream
Journey.
Compared with prior art, the effect of the present invention is positive it will be evident that specifically: the present invention solves two dimension
Code and the disadvantages mentioned above of bar code, replace Quick Response Code by the sightless image code based on digital watermark technology of human eye
And bar code, improve Consumer's Experience and improve the efficiency of POS.
