Figure 1A is the structure chart of the image retrieval system 100 of embodiments of the invention 1.
Image retrieval system 100 is different from this image of the object of the image for user is specifiedTime period (for example from the moment different from comprising the frame of object that user specifies frame) or from different shadowsPicture (for example, from take the image of gained in the place different from the image of the object that comprises user's appointment) retrievalSystem out, the object of this system is: the tracking letter that uses the dynamic object (moving body) in imageBreath, generates this to each spot for photography of the image of retrieving by the query image that is suitable for retrieval and looks intoAsk image, improve thus speed and the precision of retrieval.
Image retrieval system 100 possesses image storage device 101, input unit 102, display unit 103And video search device 104.
Image storage device 101 is storage mediums of preserving image data, can use the hard of built-in computerDisk drive or connect by networks such as NAS (network attached storage) or SAN (storage area network)Storage system and form. In addition, image storage device 101 can be also for example temporarily to preserve from cameraThe buffer storage of the image data of input constantly.
In addition, be kept at the image data in image storage device 101, as long as can be captured in trackingWhen dynamic object, utilizing, can be the data of arbitrary form. For example, the image data of preservation can be bothTaking the motion image data of gained with video camera, can be also to clap with the interval of being scheduled to by still cameraTake the photograph a succession of Still image data of gained.
Input unit 102 is that mouse, keyboard, touch-screen equipment etc. are for passing on and use to video search device 104The input interface of the operation at family. Display unit 103 is the output interfaces such as liquid crystal display, for show imageThe result for retrieval of indexing unit 104, use with user's conversational operation etc.
Video search device 104 is followed the tracks of dynamic object and detects significantly from each frame of given image dataRegion savings. If having specified, user wishes from the object of the frame search of savings, video search device104 use trace information to select to be suitable for using query image to retrieve in its a series of frame in front and backThe query image of each spot for photography of image, carry out similar image retrieval. Video search device 104Handled image, having imagined is the image that the ocean weather station observation of gained is taken in place more than position at.In addition, the object of searching object is the dynamic object arbitrarily such as personage or vehicle. Video search device 104Possess image input part 105, frame register 106, dynamic object tracking portion 107, trace information register108, marking area test section 109, marking area register 110, image database 111, query argumentInfer portion 112, query argument savings portion 113, inquiry input part 114, inquiry determination section 115 and similarImage retrieval portion 116.

Coordinate fields 243 is preserved the coordinate in the image of marking area. Characteristic quantity field 244 is preserved from aobviousThe image feature amount of work extracted region. Come according to the number of the kind of the determined marking area of system designerPrepare marking area table 240. In addition, also can not prepare marking area table, and only according to dynamic objectImage feature amount is retrieved.
The action of<each portion>
The overall structure of image retrieval system 100 has been described above. Below, at summary image retrieval systemOn the basis of 100 operating principle, the detailed action of each function part is described.
Fig. 3 is the figure of the action of the image retrieval system 100 for embodiments of the invention 1 are described.
Image retrieval system 100 is in the time of the object of retrieving in image, and a frame of for example show image, shouldThe object that frame is appeared before one's eyes carries out similar image retrieval as inquiry. The key diagram 301 of Fig. 3 represents that user selectsSelect the situation of the searching object 302 in incoming frame. Searching object 302 is the illustrated inputs that comprise in imageThe dynamic object of appearing before one's eyes in multiple frames of frame. By processing described later, select to be included in these multiple framesImage (being rest image) some as retrieval and inquisition of searching object 302.
The direction that the additional arrow of searching object 302 is represented to object (is for example personages at searching object 302Situation under, be the positive direction of health). If the direction difference of general object, characteristics of image quantitative changeChange. In addition, according to the frame of selecting, the distinctive district of the searching object 302 of also sometimes originally not appearing before one's eyes outTerritory (marking area). For example, the in the situation that of personage, in rearward situation, do not appear before one's eyes outBecome the face region of feature, therefore cannot use the retrieval of face feature. Multiple frames from image are searchedRope is suitable for the very spended time of operation of the inquiry of similar image retrieval, becomes and obtains institute till result for retrievalThe factor of the time increase needing, the reduction of retrieval precision.
In the present invention, by using the trace information of dynamic object, from same portable cord determine one withOn suitable inquiry, use this inquiry to carry out similar image retrieval. Key diagram 303 is used in image mobileThe form in path (portable cord) express the trace information of searching object 302. Specifically, key diagram303 shown curves according to the order in moment of taking each frame by the successive frame from Extraction of ImageThe coordinate of searching object 302 on picture couples together, and the direction indication retrieval of the arrow of the end of curve is rightResemble 302 directions that move, the profile of key diagram 303 is equivalent to the profile of each frame. In addition, key diagram 303Shown portable cord is from oblique upper to the searching object 302 of looking down the picture of taking like that spot for photographyMobile route. Therefore, the downside of picture is equivalent to front side (in the coverage of this spot for photographyApproach a side of camera), the upside of picture is equivalent to inboard (in the coverage of this spot for photographyFrom the side away from camera). In key diagram afterwards, if not special record is also used with above-mentionedSame method shows the portable cord of dynamic object.
In addition, the mobile route of image that is certain dynamic object at certain portable cord, following sayingIn bright, sometimes this dynamic object is recited as " dynamic object on portable cord ", by the figure of this dynamic objectPicture is recited as " image on portable cord ", and the marking area of the image on portable cord is recited as to " portable cordOn marking area ".
In key diagram 303, for example searching object 302 at place A, the B on portable cord, C, D placeImage as shown in key diagram 304, for take from different directions respectively same searching object 302 (In this example, be personage) image of gained, the outward appearance difference presenting in each image, therefore obtains differenceImage feature amount. The multiple images that obtain are like this all to use as the inquiry of similar image retrievalQuery candidate, can use obtained whole query candidate to carry out similar image retrieval. But, from upperState such successive frame and can obtain many query candidate, therefore owing to using these many query candidateIncrease retrieval time. In addition, (for example determine to show the suitable of result for retrieval for the integrated approach of result for retrievalThe method of order) also have problems.
On the other hand, in the present invention, use the portable cord information to each spot for photography savings, automaticallyDetermine suitable inquiry, reduce retrieval number of times. For example, shown in key diagram 305, (scheming in certain placeIn 3, be recited as place 1) locate to take the portable cord of each dynamic object of being appeared before one's eyes out in the image of gained. ?In this example, as shown in the arrow of portable cord, many dynamic objects moving inwards above from picture, because ofThis can think and in the image of gained is taken in this spot for photography, not comprise the positive figure of many dynamic objectsPicture. Therefore, the image that is difficult to place such be taken to gained is as object, for example, by personage's faceThe feature in what feature was such appear at object front is carried out similar image retrieval as inquiry.
In the incoming frame shown in key diagram 301, include the image towards the searching object 302 of certain direction.In this image, be not limited to comprise suitably in the inquiry of the image of place 1 place's shooting gained as retrievalFeature. But, in the frame before and after it, as shown in key diagram 303 and 304, comprise towards various sidesTo the image of searching object 302, their part is likely taken gained as retrieval at 1 place, placeImage inquiry and comprise suitable feature.

Fig. 5 is the inferring of the query argument carried out of video search device 104 of explanation embodiments of the invention 1The figure processing.
If a certain number of above image is put aside in image database 111, about each shooting groundPoint, can obtain many portable cords. In key diagram 501, as an example, represent about with the saying of Fig. 3The portable cord that the place 2 that bright Figure 30 7 is identical obtains. For each portable cord, portable cord characteristic quantity is kept atIn trace information table 220. Query argument is inferred portion 112 and is first carried out cluster for these portable cord characteristic quantities(clustering) process, in key diagram 502, find out the representative portable cord 502A representing with the arrow of thick lineAnd 502B. In clustering processing, can use the such common method of k-means method.
Then, query argument is inferred portion 112 and is obtained and belonging to each group (cluster) from image database 111Portable cord on the marking area that detects. Consequently, for each kind of marking area, detectedThe set of the image feature amount of the number of the marking area going out and the marking area detecting. Get rid of at thisThe marking area of the kind of the discontented predetermined number of number that the stage detects is selected in remaining marking areaBe best suited for the marking area of retrieval.
Be suitable for the method for marking area of retrieval as judgement, for example, can consider to use image feature amountThe method of variance ratio.
The video search device 104 of Fig. 6 embodiments of the invention 1 uses in order to judge marking areaThe key diagram of the variance ratio of image feature amount.
The variance ratio of image feature amount is the image feature amount of the marking area that detects in same portable cordVariance yields (portable cord internal variance) and portable cord between the ratio (variance of variance yields (variance between portable cord)Variance between ratio=portable cord/average portable cord internal variance). In key diagram 601, schematically represent that variance ratio is largeSituation under the example of variance of image feature amount of marking area of each portable cord. In this example, withIn one portable cord, the time fluctuation of the image feature amount of same object is few, between portable cord, i.e. different objectsBetween the difference of image feature amount large, therefore easily find object by the retrieval of feature value vector.
On the other hand, showing of the each portable cord in the situation that of schematically representing that variance ratio is little in key diagram 602The example of the variance of the image feature amount in work region. In this example, cannot separate the characteristic quantity of an objectSpace and with it the characteristic quantity space of different objects, therefore find and original object of wishing retrieval mistakenlyThe possibility of the different object of thing is high, is difficult to obtain effective result for retrieval.
Query argument is inferred portion 112 each marking area is obtained the variance ratio of image feature amount, selects variance ratioHigh marking area, registers in query argument savings portion 113.
In the example of Fig. 5, as shown in key diagram 501 and 502, many portable cords of obtaining are categorized asComprise from picture above towards the group of many portable cords of left back, comprise from left back towards aboveThe group of many portable cords. In this example, the representative portable cord 502A of each group and 502B are not actualIn many portable cords of obtaining one, but the generation generating according to many portable cords that are included in each groupTable property portable cord. In addition, also will be included in portable cord in each group and be recited as the representative portable cord of each groupSimilar portable cord.
The key diagram 503 and 505 of Fig. 5 is illustrated respectively in and represents portable cord 502A and represent portable cord 502BSimilar portable cord on the example of the relevant information of the marking area that detects. Specifically, at key diagramIn 503 and 505, as the example of the information relevant with marking area, demonstrate marking area kind,The example of the number of the marking area of the various species detecting, the image of marking area and characteristic quantityVariance ratio. In the example of Fig. 5, each dynamic object is personage, and therefore the kind of marking area comprises and " movesKinetoplast " (being dynamic object entirety), " face " and " style and colour of clothes ", but also can comprise other kinds.
In the example of Fig. 5, the similar portable cord that represents portable cord 502A comprise many from picture beforeFacing to the portable cord of left back, therefore detecting kind is the many remarkable of " moving body " and " style and colour of clothes "Region, but do not detect the marking area that kind is " face ". In this example, the image of " style and colour of clothes "The variance ratio of characteristic quantity is larger than " moving body ", therefore " style and colour of clothes " is chosen as to the remarkable district that is suitable for retrievalThe kind 504 (being also recited as below " the effectively kind of marking area ") in territory. On the other hand, representative is mobileThe similar portable cord of line 502A comprises many left backs from picture towards portable cord above, therefore inspectionMeasuring kind is the marking area of enough numbers of " face ", the variance ratio maximum of its image feature amount, thereforeSelect " face " kind 506 as effective marking area.
More particularly, for example also can select to detect number and variance yields all exceed predetermined value etc., meet pre-The kind of fixed condition. For a group, multiple kinds meet in the situation of above-mentioned condition, both can selectSelect the whole of them, also such as one of selecting party difference maximum etc., and then dwindle according to other conditionsThe scope of kind.

(Figure 14: step S1405)
Trace information register 108 merges portable cord, upgrades correspondingly following of image database 111Track information table 220, goer body surface 230.
The method of embodiment 1 is selected inquiry to every portable cord, therefore must suitably record the spy of portable cordThe amount of levying. But the feature of the portable cord obtaining by the tracking of dynamic object only represents in imageThe movement of two dimension, does not consider depth information (in other words, the distance from camera to dynamic object).Therefore, according to the method to set up of camera, even same portable cord, the marking area on this portable cordState also likely change.
Figure 15 is that the degree of depth of considering of the image retrieval system 100 for embodiments of the invention 2 are described is believedThe figure of the correction of the trace information of breath.
For example, in the key diagram 1501 and 1502 of Figure 15, be illustrated respectively in place 1 and place 2 is clappedTake the photograph portable cord, each the portable cord of the dynamic object (being personage) that the image of gained comprises in this exampleOn the example of multiple images. In this example, dynamic object ID:1~3 shown in key diagram 15013 images are near the starting point of portable cord, near intermediate point and near terminal, to take one dynamically respectivelyThe image of object gained. Marking area 1501A~1501C is respectively the image of dynamic object ID:1~3Marking area (being face in this example). Equally, dynamic object ID:11~13 shown in key diagram 15023 images be respectively near the starting point of portable cord, near intermediate point and near terminal, take one movingThe image of state object gained. Marking area 1502A~1502C is respectively the figure of dynamic object ID:11~13The marking area of picture.
The shape of these 2 portable cords is consistent, but almost do not have the portable cord shown in key diagram 1501 fromPoint to the variation of the depth direction of the position of the dynamic object of terminal (in other words, dynamic object and camera itBetween distance almost do not change), on the other hand, the dynamic object of key diagram 1502 is from the inside towards aboveMobile. This is according to learning below: as shown in the size 1503 of the marking area on portable cord, and significantly districtThe size of territory 1501A~C is identical (for example 10cm × 10cm) all, on the other hand, marking area 1502A,The size of B and C (for example respectively as 5cm × 5cm, 7cm × 7cm and 10cm × 10cm thatSample) change.
Even if this means the dynamic object as the changes in coordinates on the picture at each place shooting gainedThe shape of mobile route identical, as the variation of the three-dimensional coordinate in the space of each spot for photography dynamicallyThe actual mobile route of object also has a great difference. Under these circumstances, the remarkable district on each portable cordThe outward appearance in territory has a great difference sometimes, therefore in order to select more suitable retrieval and inquisition, it is desirable to make to be used asFor the mobile route of the dynamic object of the variation of the three-dimensional coordinate in the space of spot for photography (has been given the degree of depthThe portable cord of information).
Therefore, in the present embodiment, trace information register 108 is used the large of marking area on portable cordLittle by 1503, for the knowledge in advance 1504 of this marking area, give depth information to portable cord. Know in advanceKnowing 1504 is normal sizes of the marking area of each kind, for example, be the feelings of face in the kind of marking areaUnder condition, be 25cm × 25cm etc., in addition, the setting position of the camera that comprises each spot for photography place(particularly height), setting party are to information such as the focal lengths of the camera lens of (the particularly angle of depression) and camera.According to the size of the marking area of these information and actual photographed gained, can infer and comprise this marking areaDynamic object is with respect to the distance of camera.
Goer body surface 230 also can also have the depth characteristic amount word of the depth information of preserving dynamic objectSection 236. For example, the size of the marking area on portable cord is 10cm × 10cm, by itBe kept in depth characteristic amount field 236 with the ratio " 10/25 " of normal size 25cm × 25cm. FollowTrack information register 108 according to depth characteristic amount, to relevant in advance the knowing such as the setting position of above-mentioned cameraKnow, the portable cord of the mobile route that represents the dynamic object on picture is transformed to the three-dimensional that represents spot for photographyThe portable cord of the mobile route in space, the characteristic quantity of the portable cord after computational transformation. By the feature calculatingAmount, be kept at for example trace information table 220 consideration in the portable cord characteristic quantity 224 of the degree of depth.
