Abstract
A video continuous analytical method based on camera phone is characterized in that an acquisition module continuously obtains image information waiting to be analyzed by an image gathering installment of the camera phone until the analysis module succeeds in analyzing; the analysis module extracts the last-gathered integrated image information to analyze, and is to analyze when the first image is gathered; then, the obtained integral image information is abstracted and analyzed in a ''first analyzing and later gathering '' way until the analysis is successful; the image acquisition restriction of cell phone users is weakened and the user operation is simplified by continuously analyzing the video; the video analysis efficiency is effectively raised by adopting the strategy of ''first analyzing and later gathering ''.
Description
Technical field
The invention belongs to computing machine, Flame Image Process, the communications field, be specifically related to a kind of video continuous analytical method based on shooting mobile phone.
Background technology
At present mobile phone has nimble advantage such as small and exquisite, easy to carry, and is therefore more and more general based on the embedded development of mobile phone, also is more and more wider based on the Video Applications scope of shooting mobile phone, mobile phone two-dimension code, the electronic bill released such as 2006 years China Mobile; Application number is the 200610125516.4 a kind of antifake method for products that have mobile phone two-dimension code that propose; Application number is " method of using image recognition to carry out the collection and the typing of card information in the mobile phone " of proposition in 200510026492.2 etc.
At application number is mobile phone and the input method thereof that proposes a kind of inputting text by taking pictures in 200410091832.5: the image input block by reality is gathered text image to be imported from the outside, utilize the contrast recognizer to analyze the morphological feature of text image, the pictorial information of typing is converted into corresponding needed text formatting.
At application number is to propose to use image recognition to carry out the collection and the input method of card information in 200510026492.2: mobile phone obtains the image information of business card by taking lens; Mobile phone carries out pre-service to image; Mobile phone carries out printed page analysis and Region Segmentation to pretreated image; Mobile phone carries out literal identification to cutting apart each zone, back; Mobile phone carries out data identification and information analysis to the literal content identified; Data are deposited in the telephone directory of mobile phone.
More present handset programs based on image recognition, the especially program of J2ME exploitation, normally carry out as follows:
1) starts the handset image recognizer;
2) sharpness of image to be identified in the adjustment mobile phone display screen;
3) by the key of taking pictures;
4) the handset image recognizer is discerned the image of taking pictures just now, and user waiting prompt;
5) if recognition failures then point out User Recognition failure and require the user to carry out content again and choose;
6) user repeated for 2～5 steps, up to discerning successfully, entered next step treatment step again.
In above-mentioned patented method, all do not consider the problem of following several respects:
1) image information does not meet condition for identification, how to handle?
2) but the user does not know how to obtain recognition image information;
3) whether user's interactive operation frequent?
4) whether the time of user's wait oversize?
Summary of the invention
The object of the invention is to solve problem recited above, proposition is based on the video continuous analytical method of shooting mobile phone, continuous analysis by video, with image acquisition constraint and the simplification user operation of reduction to the cellphone subscriber, and by adopting effectively raising video analysis efficient of " the back collection is analyzed earlier " strategy.
Technical scheme of the present invention is: a kind of video continuous analytical method based on shooting mobile phone is characterized in that: acquisition module constantly obtains image information to be analyzed by the image collecting device of shooting mobile phone, until analysis module analysis success; Analysis module extraction time goes up the last complete image information of gathering and analyzes, and just begins to analyze after promptly collecting first image, and the complete image information of just extracting collection in the mode of " analysis is earlier gathered in the back " is analyzed thereafter, until analyzing successfully.Such as, when acquisition module deposits the image information of gathering in formation, adopt " back is gathered earlier and analyzed " strategy, the image information of i.e. back collection is inserted into the corresponding position of formation according to the graphical analysis extracting rule, if the graphical analysis extracting rule is to extract in the formation first, then the back image information of gathering is inserted into the foremost of formation.
Aforesaid video continuous analytical method based on shooting mobile phone, it is characterized in that: image collector is changed to the camera of shooting mobile phone.
Aforesaid video continuous analytical method based on shooting mobile phone, it is characterized in that: acquisition module obtains image information continuously, and its time interval is fixed, or adjustable.
Aforesaid video continuous analytical method based on shooting mobile phone, it is characterized in that: the size of formation is fixed, and maybe can increase.
Aforesaid video continuous analytical method based on shooting mobile phone is characterized in that: if the size of formation is fixed, then judge whether to surpass when the insertion new image information and specify size, come last image information if surpass then delete.
Aforesaid video continuous analytical method based on shooting mobile phone is characterized in that: if the size of formation can increase, then directly new image information is inserted in the formation.
Aforesaid video continuous analytical method based on shooting mobile phone is characterized in that: analysis module adopts one or more of the following step: image gray processing, filtering, image binaryzation, image segmentation, image characteristics extraction, comparative analysis.
Beneficial effect
The invention has the beneficial effects as follows, the video continuous analytical method that utilizes the present invention to propose based on shooting mobile phone, weakened on the one hand to cellphone subscriber's image acquisition constraint and simplification user operation, by adopting " back is gathered earlier and analyzed " strategy can effectively improve video analysis efficient, shorten period of reservation of number on the other hand.
Description of drawings
Fig. 1 is the continuous analysis process figure of video of the invention process.
Embodiment
Embodiments of the invention as shown in Figure 1, based on the continuous analysis process figure of the video of shooting mobile phone.
For example: in mobile phone two-dimension code was used, the user started video application, and acquisition module is created video flowing and is presented on the mobile phone screen in the video application, and the mobile phone two-dimension code image information that the user sees by mobile phone screen is adjusted the sharpness of image; In user's adjustment process, the continuous capturing video of acquisition module in the video application is supposed more existing image informations in formation this moment, the order M that these image informations are to be analyzed
W-1, M
W-2, M
W-3..., at video application analysis module analysis image information M
wThe time, acquisition module obtains new image information M
W+1, video application acquisition module basis " back is gathered earlier and analyzed " is tactful in M
W+1Deposit in the formation.Suppose that formation is not provided with fixed measure, then pending order is in formation: M
