Such program modules may be included in the digital data tagging apparatus 100 in the form of an operating system, an application module, and other program modules, and may be physically stored on various known storage devices. In addition, these program modules may be stored in a remote storage device that can communicate with the digital data tagging device 100. Such program modules include, but are not limited to, routines, subroutines, programs, objects, components, data structures, etc. that perform particular tasks or execute particular abstract data types, described below, in accordance with the present invention.

First, a user acquires digital data, for example, a portrait file, through the digital data acquisition unit 110. The person photo file may be acquired by directly taking a picture through a device embedded in the digital data tagging device 100 such as a camera module, but may be acquired by being transmitted from the outside.

Through the input unit 120, a user inputs various commands related to controlling the digital data tagging apparatus 100. For example, by inputting the relevant information for tagging the person photo file obtained from the digital data acquisition unit 110 through the input unit 120, or for other person photo files using the person tag information provided in the person photo file According to the present invention to be described later, a command for assigning a person tag may be input.

For example, the display unit 130 outputs a person photo file to which the person tag information is assigned according to a command input through the input unit 120, or a person consisting of a plurality of person photo files that need to be given the person tag information. You can print a list of photos. In addition, the display unit 130 may provide a standby screen including an operating system to perform a user's command.

In addition, the controller 160 may group the plurality of person photo files to which the person tag information is not assigned by the generated time or the generated place. Or may be referred to as clustering], and then control to allow person tag information to be collectively assigned to the group (cluster), or to each other among a plurality of person photo files not provided with person tag information. A person photo list may be configured such that person photo files having similar person images are arranged adjacent to each other so that person tag information may be collectively applied to the person photos of the list. The tagging process according to the present invention performed by the control of the controller 160 will be described in more detail below in the relevant part of the present specification.

On the other hand, as mentioned above, the configuration of the module installed in the digital data tagging apparatus 100 can be freely modified within the technical level of those skilled in the art, and can be modified to a more advanced configuration in consideration of the entire system.

Hereinafter, a process performed in the memory unit 150 described above with reference to FIG. 2 will be described for each component.

FIG. 2 is a block diagram illustrating the memory unit 150 of FIG. 1 in more detail.

The memory unit 150 includes a digital data storage unit 152, a portrait photo list generation unit 154, and a portrait photo list transmission unit 156.

First, the digital data storage unit 152 stores various kinds of information (ie, various kinds of information on the person photo file) regarding a plurality of digital data generated by the digital data acquisition unit 110. The stored plurality of portrait photo files may include portrait photo files to which person tag information is assigned and portrait photo files to which person tag information is not assigned.

The portrait picture list generation unit 154 may include a plurality of candidate portrait pictures having a person image having a high probability of being determined as a person image included in the person photo file with respect to the person photo file to which the person tag information selected by the user is assigned. The digital data storage unit 152 searches the digital data storage unit 152 to generate a list including the found plurality of candidate person photographs. Preferably, by extracting from among a plurality of portrait photo files having no image tag information, the portrait photo files having an image showing a high degree of similarity to the person image included in the predetermined selected portrait photo file to which the person tag information is given; Create as a list. The extracted person photo files are sorted by giving priority to the person photo files having a face image more similar to the face image of the person of the selected picture.

According to another exemplary embodiment of the present disclosure, the portrait photo list generator 154 may include a plurality of candidates having a person image having a high probability of being determined as a person image included in the person photo file to which the person tag information selected by the user is assigned. The person photographs are retrieved from the digital data storage unit 152 to generate a list composed of face images of individual persons included in the found plurality of candidate person photographs. Individual face images included in the list are sorted by prioritizing face images more similar to face images of persons included in the selected photo file.

According to still another preferred embodiment of the present invention, after grouping a plurality of person photo files stored without tag information by a generated time or a place, each group includes more person photo files. By listing them in order, you can create a list of portrait photos.

According to another preferred embodiment of the present invention, it is possible to generate a portrait photo list in which a plurality of portrait photo files that are similar to each other among portrait photo files to which no person tag information is assigned are arranged adjacent to each other. .

The portrait photo list transmitter 156 transmits the portrait photo list to the display 130 so that the portrait list generated by the portrait photo list generator 154 can be displayed according to various embodiments as described above.

Hereinafter, the similarity determination logic for generating a portrait photo list after searching for images of the portrait photograph as described above will be described.

Generation of Candidate Portrait Photo List Based on Judgment of Similarity Between Portrait Photos

As a representative technique for managing digital data using conventional face recognition, reference may be made to the invention described in "Leveraging Face Recognition Technology to Find and Organize Photos", a paper co-authored by Andreas Girgensohn of FX Palo Alto Laboratory. The content of the article should be considered to be incorporated in its entirety herein).

According to this, it is necessary to be able to recognize that the face of the person is the same even if the angle and the facial expression of the face are different. Therefore, by using a known recursive contour approximation algorithm, a face part such as the tip of the eye, the tip of the mouth, the nostril and the ear After recognizing the specific position of as coordinates, extracting and calculating the geometric and distance relations according to the angle and distance, and comparing the data, it is possible to identify the person image through the recognition according to the features of the face shape.

For example, A = {a1, a2,... , aw} is a shape feature set of a query object, that is, a feature set of an image included in a person photo file to which tag information is given, and B = {b1, b2,... , bw} is referred to as a shape feature set of an object stored in a database, that is, a feature set of an image included in a person photo file to which no tag information is assigned, which is stored in the digital data storage unit 152. Therefore, if the total number of shape features of B corresponds to, for example, more than 70% of the number of shape features of A, similarity value between each feature of query object A and image object B can be determined by designating B as a similar candidate (similarity). In the determination, as described above, weighting according to a part in the face may be more focused on a part that makes a major contribution to determining similarity). The shape feature is used to find the eyes and eyebrows of the face based on the face area among the person images included in the tagged person photo file, and based on the face proportional information, to identify each area of the region such as the lips and the nose. Can be obtained by extraction. For example, in the case of the lips, distances and angles are measured clockwise from feature points marked around '+' from the center of gravity, and the lips may be determined to be large or long based on the measured values. Thereafter, the portrait picture list generation unit 154 uses the known recursive contour approximation algorithm to determine coronary information through extraction and similarity determination for each part of the face region of the image included in the person photo file to which the tag information is assigned. The numerical values for the distance and the angle required for the operation are obtained, and the images including coronary information related to the search are compared with the numerical values stored in the digital data storage unit 152. That is, a plurality of candidate person images having a high probability of being determined as a person image included in the person photo file to which the tag information is assigned are searched for. Herein, the reference value of the similarity is described as 70% (excess) as an example, but the reference value of the similarity may be increased or decreased as necessary. The candidate portrait pictures thus retrieved may be displayed in the candidate person photo list in order of high similarity.

Preferably, the image of the face of the person is extracted from the photo file having the person tag information and used as a criterion for determining similarity. The face image and the corresponding coordinates of the person are also extracted from the candidate person photos searched for. Similarity determination may be performed by comparing the image of the person face with the face images of the person extracted from the candidate person pictures. In this case, the person tag of the person photo file including the image of the person face as a reference may be given as tagging information to the candidate person photo file. At this time, the tagging information may include coordinates representing the shape feature of the face image of the candidate portrait.

That is, in the case of adopting the above configuration, it is also possible to use a person face image list instead of the person photo file list, and to use the reference face image instead of the reference person photo file, thereby tagging the person photo file.

Further, more preferably, a portrait photo file having a high probability of being determined to include a face image of a person included in a portrait photo file having existing person tag information among the portrait photo files to which the person tag information has not been given yet. You may want to use it as a reference portrait file. At this time, the recommended person photo file is the highest compared to the person face image included in the person photo file to which the person tag information has been assigned (which can be compared based on the similarity determination method between the face images as described above). It may include a person face image showing a similarity. However, in consideration of the importance of the reference person photo file, the recommendation may be determined by the user's manipulation. Of course, as described above, the recommendation may be a reference person face image instead of the reference person photo file, and the similarity determination and recommendation process in this case is similar to the case of using the reference person photo file.

Assigning Person Tag Using Candidate Photo List

The above-described candidate person photo list displayed through the display unit 130 is provided with tag information manually or automatically by the control of the controller 160 according to a user's confirmation operation. For example, for a candidate person picture list including person picture files having a person image having a high similarity with respect to a person image included in a selected person picture file to which tag information is assigned, the tag information may include a name of the person, If the tag is tagged with an alias, a simple tagging may be implemented by selecting a name or selecting an alias according to a user's preference. In addition, the digital data tagging apparatus 100 may further set information such as an email address and a phone number of the person according to the selected person photo file as a tag for the person photo file included in the candidate person photo list. Regarding the types of tag information that can be set above, the same Applicant as the present application is well represented in Korean Application No. 10-2006-0014040 filed on Feb. 14, 2006, in "Tag Method and System for Digital Data". Let's find out.

Hereinafter, a process of assigning tag information to digital data according to the operation of each component of the digital data tagging apparatus 100 according to the present invention will be described.

3 is a flowchart illustrating a person tag providing process according to a first embodiment of the present invention.

First, the user acquires digital data, for example, a portrait photo file, through the digital data acquisition unit 110 (S310). Tag information (preferably, person tag information) may be provided to the acquired person photo file manually or automatically by the user (S320). Preferably, the similarity between the acquired portrait photo file and the face image of the existing portrait photo file is measured, and when the similarity is equal to or greater than a predetermined threshold, for example, 80% or 90% or more, tags are obtained in the acquired portrait photo file. The information can be given and used as a reference portrait file. The person photo file to which the person tag information has been assigned is a reference person picture file, which is used when the person tag information is assigned to a plurality of person picture files stored in the digital data tagging apparatus 100 without the person tag information. Can be. Next, a plurality of person photo files including a person image having a high similarity to a person image included in the person photo file to which the person tag information is provided from the memory unit 150 are stored without tag information. The image is searched from the portrait file (S330). The retrieval of a person image by measuring similarity may be performed with reference to the invention described in "Leveraging Face Recognition Technology to Find and Organize Photos" by Andreas Girgensohn et al. (As described above). . Through this similarity measurement process, the list of candidate portrait photos composed of the portrait photo files including the portrait image of the portrait photo file to which the person tag information is assigned and the portrait image having the highest similarity is arranged in the order of the highest similarity. Displayed through 130 (S340). Accordingly, the user selects the person photo files including the person image of the highest similarity and assigns the person tag information by using the person tag information set here (S350). Of course, even in this case, the user may collectively give the person tag information only to the desired person photograph through manual operation. In any case, as the collective assignment of the person tag information is repeated, the number of person pictures not including the person tag may be significantly reduced.

4 is a diagram schematically illustrating a display of a user interface for providing a person tag according to a first embodiment of the present invention. Referring to FIG. 4, it is relatively inferior to three portrait pictures (402, 404, 406) including a person image having a considerably higher similarity to the person image included in the reference picture 400 having the person tag information. Two portraits 408 and 410 showing the similarity are displayed in the order of similarity. According to a preferred embodiment of the present invention, the portrait pictures 402, 404, and 406 that exhibit similarities exceeding a predetermined reference value (for example, 80%) have the same person tag as the reference picture 400 at the time of default processing. There is a display (gray display) indicating that the image is to be given, and a confirmation button 414 is arranged to allow the user to visually tag the candidate pictures. This not only enables the user to collectively tag a plurality of untagged portrait photo files, but also after visual confirmation, moves the reference value bar 412, ie, increases or decreases the reference value. (The gray-colored photo changes as the reference value bar 412 moves.) By specifying individual photographic images, more accurate tagging can be performed.

Creating a Photo List and Tagging It Using the Cluster Concept

The basis for introducing the cluster (or grouping) concept can be found in the description of the mass tagging portion of Korean Patent Application No. 2006-14040 filed by the present applicant. The cluster may be classified according to the time at which the portrait file is generated or may be divided according to the place where the portrait file is generated.

According to this, a user of each digital camera can generate a person photo file at a desired time and place. However, when looking at the generation time, the place of creation, etc. of such a portrait photo file, there are many cases where the distribution is very discontinuous. In other words, a user of a digital camera tends to generate a portrait file only at a very biased time and place. Therefore, by identifying a place or time zone that is common to various portrait photo files, a mass tagging method of grouping the portrait photo files into a single cluster (cluster) and assigning a common tag to all of the portrait photo files is performed. It can exist.

This idea of lump tagging can be applied to give tags about people with high accuracy. That is, when a plurality of person photo files are included in the same cluster, if one person photo includes an image of a specific person, it is likely that the other person photo includes an image of the same person. This is because there is a high possibility that a large number of pictures will be taken by posing differently for the same person in a short time, and a large amount of pictures are likely to be taken while walking around the same person and around in the near area with different backgrounds. to be.

Therefore, based on this concept, in tagging a person's photo file with information about a person whose image is included in a person's photo file generated by being concentrated in the same time zone or in the same region, the same cluster within the same cluster may be used. In the case of using the fact that the same person is likely to appear repeatedly can be a great convenience in tagging people.

Referring to FIG. 5, a process of assigning tag information by grouping according to a time and a place where a person photo file is generated will be described. 5 is a flowchart illustrating a person tag providing process according to a second embodiment of the present invention.

First, the user acquires digital data, for example, a portrait photo file, through the digital data acquisition unit 110 (S510). Next, a portrait photo list is formed by dividing the plurality of portrait photo files stored in the memory unit 150 without the person tag information yet assigned to the generated time or the generated place. The process of grouping the person photo files by the generated time or the generated place is as described above. The formed portrait photo list is sorted according to the number of objects (number of objects per group) and displayed on the display unit 130 (S520). The user collectively assigns tag information to the group of person photograph files of the displayed person list photograph list (S530). Of course, in performing step S530, it would be natural to allow the user to tag non-collectively some photo files.

Create a list of similar portraits and tag them

Next, a process of collectively assigning tag information by measuring similarity between a plurality of photo files that are not yet given tag information stored in the memory unit 150 will be described.

6 is a flowchart illustrating a person tag providing process according to a third embodiment of the present invention.

First, a user acquires digital data, for example, a portrait photo file, through the digital data acquisition unit 110 (S610). Next, among the plurality of portrait photo files stored without tag information in the memory unit 150, photo files having similarities are grouped by similarity measurement to form a portrait photo list. As described above, the process of measuring similarity may include, for example, a distance required for coronary information through extraction and similarity determination for each part of the face region of the person image included in the person photo file using a known recursive contour approximation algorithm. By obtaining a numerical value for the angle. The person photo list thus formed is classified into a group of person photo files having high similarity to each other and displayed through the display unit 130 (S620). The user selects similar portrait photo files among the displayed portrait photo files and collectively assigns tag information to the corresponding portrait photo files (S630). For the above tagging, preferably, one portrait picture list can be displayed in order of many groups of similar portrait pictures which are judged to be similar to each other according to a predetermined criterion, whereby the user is able to display more portrait pictures. The person tag information can be given quickly.

Although the present invention has been described in connection with various embodiments as described above, it is to be understood that other variations and modifications may be implemented without departing from the spirit and scope of the invention as would be understood by those skilled in the art. It should be understood. Such modifications and variations are to be considered as falling within the scope of the invention and the appended claims.
