Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The embodiment described below is an example of a specific embodiment of the present invention, and is one of the specific embodiments of the configuration described in the claims.

FIG. 1 is a diagram showing an example of the configuration of the information processing system in the present invention. As shown in FIG. 1, the information processing system of the present invention has a configuration in which a client terminal 101 and a server device 102 are communicably connected.

The client terminal 101 is a terminal used by a user who performs labeling work on a detected object, displays a bird's-eye view image, an enlarged image, and the like, and receives a labeling instruction.

The labeling work is a work of accepting the designation of the area in which the detected object appears and the designation of the category (label) to which the detected object belongs in the displayed image. The detection object rectangle, which will be described later, is a rectangle that surrounds the area designated as the detection object.

For example, the screen shown in FIG. 3 shows an example in which the face of the person in the image is labeled as male or female, and the approximate age (for example, teens or twenties, etc.). ing. Enclose the area corresponding to the human face with a rectangle and label whether the face in the rectangle is male or female and the approximate age.

The server device 102 has a function of managing the labeling result and transmitting a screen such as FIG. 4, which will be described later, to the client terminal 101.

Details of the processing executed by the client terminal 101 and the server device 102 will be described later with reference to the drawings of FIGS. 6 and later.

Next, the hardware configuration of the information processing device applicable to the client terminal 101 and the server device 102 shown in FIG. 1 will be described with reference to FIG.

In FIG. 2, 201 is a CPU that comprehensively controls each device and controller connected to the system bus 204. Further, in the ROM 202 or the external memory 211, a BIOS (Basic Input / Output System) which is a control program of the CPU 201, an operating system program (hereinafter, OS), and various functions necessary for realizing a function executed by the PC, which will be described later, are used. The program etc. are stored.

Reference numeral 203 denotes a RAM, which functions as a main memory, a work area, and the like of the CPU 201. The CPU 201 realizes various operations by loading a program or the like necessary for executing a process from the ROM 202 or the external memory 211 into the RAM 203 and executing the loaded program.

Further, 205 is an input controller, which controls input from a pointing device such as a keyboard (KB) 209. Reference numeral 206 denotes a video controller, which controls the display on a display such as a display 210 (whether a liquid crystal display or a cathode ray tube).

The 207 is a memory controller that can be used in an external storage device (hard disk (HD)) that stores boot programs, various applications, font data, user files, edit files, various data, etc., a flexible disk (FD), or a PCMCIA card slot. It controls access to an external memory 211 such as a CompactFlash® memory connected via an adapter.

Reference numeral 208 denotes a communication I / F controller, which connects and communicates with an external device via a network, and executes communication control processing on the network. For example, communication using TCP / IP is possible.

The CPU 201 enables display on the display 210 by, for example, executing an outline font expansion (rasterization) process in the display information area in the RAM 203. Further, the CPU 201 enables a user instruction with a mouse cursor or the like (not shown) on the display 210.

Various programs described later for realizing the present invention are recorded in the external memory 211, and are executed by the CPU 201 by being loaded into the RAM 203 as needed. Further, a setting file or the like used when executing the above program is also stored in the external memory 211, and detailed description of these will be described later. This is the end of the description of FIG.

Next, a screen (basic screen) for confirming the result of labeling an image on the screen of FIG. 3 will be described with reference to FIGS. 4 and 5.

4 and 5 are views showing an example of a basic screen in the present invention.

Reference numeral 401 denotes a display area in which the detected object labeled by this labeling operation is displayed.

Reference numeral 402 denotes a category (label), and in the example of FIG. 4, a cutout image of the detected object labeled in the category of male 20s and the category of male 30s (image obtained by cutting out the detected object from the original image). ) 403 is displayed below each category 402. In category 402, the display order can be changed by dragging and dropping (for example, it is possible to move a male 20's to the right of a male 30's). Further, when the "x" button is selected, the target category is deleted from the display area 401, so that the category for which the classification has been completed can be easily deleted from the screen.

Reference numeral 403 is a cut-out image obtained by cutting out the detected object from the image. If you want to change the category 402 of the cutout image 403, you can change it to another category 402 by dragging and dropping the cutout image 403 under the change destination category 402. That is, since it is not necessary to return to the screen of the original image (FIG. 3) and change the category again, the efficiency of the labeling work of the user is improved.

When the mouse over is performed on the cutout image 403 for a predetermined time or longer, an image (peripheral area image) around the detected object is displayed as shown in 501 of FIG. At that time, since the detected object rectangle is also displayed, it is possible to correct the position and size of the rectangular detected object rectangle.

By displaying the image around the detected object, there is an effect of facilitating the judgment when it is difficult to judge the category only by looking at the cutout image 403.

For example, in the labeling of the flowers of a plant (labeling whether the buds are attached to the branches of the cherry blossoms or whether they are in bloom), the flowers are reflected in the cutout image 403, but is it one flower? Since it may be difficult to tell whether it is one flower or not from the cut-out image alone, in such a case, it is possible to easily determine whether or not it is one flower by displaying the image around the detected object. ..

Reference numeral 404 is a paging element, which is displayed when there are many cutout images 403. The scroll bar may be displayed vertically instead of paging.

Reference numeral 405 is a list box, and text can be input at the uppermost part, and only the category name that matches the input text at the beginning is displayed.

If no entry is made in the list box 405, all category names are displayed. By selecting the displayed category name and selecting the add button on the right side of the list box 405, the cutout image 403 of the added category is displayed in the display area 401 or the display area 407.

That is, the list box 405 allows the user to easily display the category to be compared in the display area, which improves the efficiency of the user's labeling work.

Reference numeral 406 is a radio button for switching the target of the cutout image 403 to be displayed in the display area 407. When "Display cutout image of all images" is selected, the labeling is performed except for the image currently being labeled. Cut-out images 403 of all completed images are displayed in chronological order, and when "Display randomly from all cut-out images" is selected, a predetermined number of cut-out images 403 (for example, 5 images) are randomly displayed in the display area. It is displayed in. In that case, the paging element 404 is not displayed. When "Display only the image cut out from the image currently being worked on" is selected, the cutout image is not displayed in the display area 407.

The merit of selecting "Randomly display from all cropped images" is that when the selection is made, the cropped images are randomly picked up from a plurality of images taken at different times and displayed in the display area 407. Rather than displaying a cropped image of one image, it is possible to compare it with cropped images of various images.

The advantages mentioned above are in the labeling of images that do not change over time, such as the labeling of plant flowers (labeling whether the branches of cherry blossoms are buds or flowers). More prominent.

407 is a display area in which a cut-out image of another image different from the image targeted for the labeling work this time is displayed.

By displaying a plurality of categories 402 in parallel in the display area 401, or displaying the same category cutout image of another image in the display area 407, the user can display the detected object currently being labeled and the past image. It is easier to relabel to a more appropriate category because it can be compared with the detected object of. This is the end of the explanation of FIGS. 4 and 5.

Next, the labeling process of the present invention will be described with reference to FIGS. 6 to 9. 6 to 10 are diagrams showing an example of a flowchart of the labeling process in the present invention.

The process shown in each flowchart is executed by the client terminal 101 or the CPU 201 of the server device 102. First, FIG. 6 will be described.

In step S601, the client terminal 101 accepts the selection of the image to be labeled from the user who performs the labeling, and acquires the image for which the selection is accepted from the server device 102.

In step S602, the client terminal 101 accepts the labeling of the image acquired in step S601 on the screen of FIG. 3 displayed on the display 210 of the client terminal 101.

Step S602 is an example of the receiving means in the present invention that accepts the designation of the area of a plurality of detected objects included in the image data and the designation of the category of the detected object.

In step S603, after receiving the labeling in step S602, the client terminal 101 displays the basic screen of FIG. 4 on the display 210 of the client terminal 101 by selecting the basic screen button 301 of FIG. 4 by the user. Execute the process to be performed. The details of the process of step S603 will be described later with reference to FIG. 7.

In step S603, the receiving means in the present invention controls the detected object that has received the designation of the area so as to display a screen divided into categories, and is further designated as the category in other images. This is an example of a display control means for displaying the screen in which the detected objects are divided into categories.

As another embodiment, the process of displaying the basic screen may be executed by selecting the "Next image" button or the "Previous image" button, and all the labeling work can be performed. You may execute the process of displaying the basic screen at the timing of completion.

In step S604, the client terminal 101 receives an operation from the user on the basic screen.

In step S605, the client terminal 101 determines whether the add button on the right side of the list box 405 has been selected by the user via the basic screen of FIG. If the add button is selected, the client terminal 101 shifts the process to step S606, and if the add button is not selected, the client terminal 101 shifts the process to step S607.

In step S606, the client terminal 101 performs a category addition process. The details of the process of step S606 will be described later with reference to FIG.

In step S607, the client terminal 101 determines whether the radio button 406 has been selected by the user via the basic screen of FIG. If the radio button 406 is selected, the client terminal 101 shifts the process to step S608, and if the radio button 406 is not selected, the process shifts to step S609.

In step S608, the client terminal 101 performs a display (update) process of the basic screen. The details of the process of step S608 will be described later with reference to FIG. 7.

In step S609, the client terminal 101 determines whether the mouse is over for a predetermined time or more on the cutout image 403 of the basic screen of FIG. The client terminal 101 shifts the process to step S610 if the mouse is over for a predetermined time or longer, and shifts the process to step S611 if the mouse is over for a predetermined time or longer.

In step S610, the client terminal 101 executes a process of displaying a peripheral image of the cutout image 403 that has been moused over for a predetermined time or longer. The details of the process of step S610 will be described later with reference to FIG.

In step S611, the client terminal 101 determines whether the category change instruction has been given by the user via the basic screen of FIG. If the category change instruction is given, the client terminal 101 shifts the process to step S612, and if the category change instruction is not given, the client terminal 101 shifts the process to step S613. The category change instruction is given by accepting from the user an operation of dragging and dropping the cutout image 403 under the category 402 of the change destination.

In step S612, the client terminal 101 receives the category change instruction and changes the category of the cutout image 403. Specifically, the "category name" of the cutout image 403 that received the category change instruction in step S611 in the cutout image table 1003 is changed.

In step S613, the client terminal 101 determines whether the end instruction has been received from the user. If the client terminal 101 receives the end instruction, it ends this process, and if it does not receive the end instruction, it returns the process to step S601.

This is the end of the description of FIG. 6, and then FIG. 7 will be described.

In step S701, the client terminal 101 transmits a basic screen acquisition request to the server device 102.

When shifting to the process of step S607 in FIG. 6, from the client terminal 101, the current display setting (including information on which radio button 406 was selected) and the list of categories displayed in the category 402 (step). (Including the category added in S606), the image ID of the image currently being labeled, and the number of cutout images 403 that can be displayed in one area of the display area 401 are also transmitted. Further, when shifting from step S602 in FIG. 6 to this processing, the labeling result (information stored in the cutout image table 1003 in FIG. 10) received in step S602 is transmitted.

In step S702, the server device 102 receives the acquisition request of the basic screen transmitted from the client terminal 101 in step S701, and executes each process from step S703 to step S707 for each category displayed on the basic screen.

When shifting from step S607 of FIG. 6 to this process, the server device 102 executes each process from step S703 to step S707 for each category included in the list transmitted from the client terminal 101. On the other hand, when shifting from step S602 of FIG. 6 to this process, each process from step S703 to step S707 may be executed for all the categories specified in the labeling operation of step S602. , Nothing may be displayed in the display area 401 or the display area 407 without executing each process from step S703 to step S707. When nothing is displayed in the display area 401 or the display area 407, the cutout image 403 is displayed in the display area 401 or the display area 407 only after the category is added in step S606.

In step S703, the server device 102 acquires a cut-out image (cut-out image to be displayed in the display area 401) of the detected object labeled in the category to be processed as a result of the labeling work received in step S602 of FIG. ..

In step S704, the server device 102 determines whether the radio button 406 of "display only the image cut out from the image currently being worked on" is selected on the basic screen of FIG. If the radio button 406 of "display only the image cut out from the image currently being worked" is not selected, the server device 102 shifts the process to step S705. When shifting to this process from step S602 of FIG. 6, it is determined whether or not the default setting is "display only the image cut out from the image currently being worked". The case where the radio button 406 of "display only the image cut out from the image currently being worked" is selected is the case where the cut out image is not displayed in the display area 407, for example.

In step S705, the server device 102 acquires a cut-out image of the detected object labeled in the category to be processed in another image different from the image targeted for the labeling work this time.

In step S706, the server device 102 determines whether the radio button 406 of "randomly display from all cropped images" is selected on the basic screen of FIG. If the radio button 406 of "randomly display from all cropped images" is selected, the server device 102 shifts the process to step S707. When shifting to this process from step S602 of FIG. 6, it is determined whether or not the default setting is "randomly display from all cropped images".

When the radio button 406 of "display randomly from all cropped images" is not selected in step S706, the radio button 406 of "display cropped images of all images" is selected on the basic screen of FIG. Therefore, in step S706-1, the server device 102 acquires a cut-out image of all the images for which labeling has been completed, except for the image currently being labeled.

In step S707, the server device 102 randomly acquires the number of images that can be displayed in the display area 407 from the cutout image acquired in step S705.

The cut-out image acquired in step S705, step S706-1, and step S707 is an image stored in the image table 1002 based on the information stored in the cut-out image table 1003 stored in the external memory 211 of the server device 102. It is an image cut out from the data. Which cutout image corresponds to the display target category can be specified by referring to the "category name" of the cutout image table 1003.

In step S708, the server device 102 generates a basic screen including the cutout image acquired in step S703, step S705, step S706-1, and step S707, and transmits the basic screen to the client terminal 101.

In step S709, the client terminal 101 receives the basic screen transmitted from the server device 102 in step S708, and displays it on the display 210 of the client terminal 101 in step S710.

This is the end of the description of FIG. 7, and then FIG. 8 will be described.

In step S801, the client terminal 101 transmits a request for acquiring a cutout image of the selected category to the server device 102 when the add button is selected in the category displayed in the list box 405. do.

At this time, the client terminal 101 also transmits the current display setting, the image ID of the image currently being labeled, and the number of cutout images 403 that can be displayed in one area of the display area 401.

In step S802, the server device 102 receives the acquisition request of the cutout image transmitted from the client terminal 101 in step S801, and executes the processes of steps S803 to S807 with respect to the category to be added (display target category). Since each process from step S803 to step S807 is the same process as each process from step S703 to step S707 in FIG. 7, description thereof will be omitted.

In step S808, the server device 102 transmits the cutout image acquired in step S803 and step S805 to the client terminal 101.

In step S809, the client terminal 101 receives the cut-out image transmitted from the server device 102 in step S808, reflects it on the basic screen, and displays it.

This is the end of the description of FIG. 8, and then FIG. 9 will be described.

In step S901, the client terminal 101 requests the acquisition of the cutout source image by transmitting the image ID of the cutout image 403 that has been moused over for a predetermined time or longer to the server device 102.

In step S902, the server device 102 receives the original image acquisition request transmitted from the client terminal 101.

In step S903, the server device 102 acquires the original image based on the image ID included in the acquisition request of the original image transmitted from the client terminal 101.

Specifically, among the "IDs" of the cutout image table 1003, the image path in the same row as the ID that matches the image ID of the cutout image 403 is specified. Next, the original image is specified and acquired by specifying an image that matches the specified image path from the "image path" of the image table 1002.

In step S904, the server device 102 uses the coordinates of the cut-out image (“cut-out image position” of the cut-out image table 1003) and the resolution of the original image (“resolution” of the image table 1002) to display the peripheral area. Calculate the coordinates. Specifically, for example, taking FIG. 11 as an example, the coordinates of the original image so as to be 9 times the size of the cut-out image are calculated around the cut-out image (cut if it protrudes).

In step S905, the server device 102 transmits the original image, the coordinates of the peripheral area, and the cutout position of the cutout image to the client terminal 101.

In step S906, the client terminal 101 receives the original image, the peripheral area coordinates, and the cutout position (position of the detection object rectangle) of the cutout image from the server device 102.

In step S907, the client terminal 101 cuts out a peripheral area from the original image and draws a frame (detection object rectangle) at the cutout image position.

In step S908, the client terminal 101 displays a peripheral area image for editing the cutout position shown in 501 of FIG.

This is the end of the description of FIG. 9, and then FIG. 10 will be described.

FIG. 10 is a diagram showing an example of various data tables. The various data tables of FIG. 10 are stored in the external memory 211 of the server device 102. However, the cutout image table 1003 is also stored in the external memory 211 of the client terminal 101.

The category table 1001 is a table in which the category of the detected object (information indicating what it is) is registered. The category name to be registered differs depending on what the object detector to be detected is constructed. When constructing a detector that detects the gender and age of a person included in an image as in this embodiment, categories such as male / female, teens / 20s are registered.

The image table 1002 is a table for managing the original image to be labeled, and the image table 1002 includes an ID (image ID) for identifying the image, an image path indicating the storage destination of the image, and an image resolution.

The cut-out image table 1003 is a table in which information indicating which category of detected object exists in which region of which image is registered. For example, the detected object specified by ID: 1 is image: 1. It shows that the face of a man in his thirties exists in the region (cutout image position) specified by (14, 20, 30, 50) of jpg.
