2019 AUG 14 (NewsRx) -- By a News Reporter-Staff News Editor at Entertainment Business Daily -- According to news reporting originating from Alexandria, Virginia, by NewsRx journalists, a patent by the inventors Takahashi, Yusuke (Tokyo, Japan); Ikeda, Hiroo (Tokyo, Japan), filed on June 17, 2013, was published online on August 12, 2019.

The assignee for this patent, patent number 10,368,010, is NEC Corporation (Minato-ku, Tokyo, Japan).

Reporters obtained the following quote from the background information supplied by the inventors: “Aspects of the present invention relate to an image processing system, an image processing method, and a program.

“In recent years, systems for carrying out monitoring over a wide range using video images from a plurality of cameras are being considered. For example, Patent Publication JP-A-2008-219570 discloses a device that is capable of appropriately tracking (monitoring) a person across cameras using inter-camera coupling relation information. The device determines a correspondence relation of a person in accordance with a similarity in person visual features between a point where a person appears in a camera view (an appearing point) and a point where the person disappears from the camera view (a vanishing point).

“When a correspondence relation of a person is automatically determined according to similarity as is the case of the device described in Patent Publication JP-A-2008-219570, errors occur with a probability. In consideration thereof, there are demands for person re-identification with human involvement.

“However, person re-identification by a human initiative conceivably results in complicating operations. When operations for re-identification become too complicated, work for re-identification becomes preoccupying and causes problems such as paying less attention to monitoring and creating a psychological obstacle to use.”

In addition to obtaining background information on this patent, NewsRx editors also obtained the inventors’ summary information for this patent: “Some of the aspects of the present invention have been made in consideration of such problems, and an object of these aspects is to provide an image processing system, an image processing method, and a program capable of re-identification of a person appearing in a video image with a simple operation.

“An image processing system according to the present invention includes: input means for accepting input video images captured by a plurality of video cameras; first display control means for causing at least one video image among the video images inputted from the input means to be displayed by a display device; registering means capable of registering one or more persons appearing in the video image displayed by the display device; and second display control means for selectably displaying, when a person appears in the video image displayed by the display device, person images which are associable to the person and which are related to one or more persons registered by the registering means in a vicinity of the video image.

“An image processing method according to the present invention includes the steps of: accepting input of video images captured by a plurality of video cameras; causing at least one video image among the inputted video images to be displayed by a display device; registering one or more persons appearing in the video image displayed by the display device; and selectably displaying, when a person appears in the video image displayed by the display device, person images, which are associable to the person and which are related to one or more registered persons, in a vicinity of the video image.

“A program according to the present invention causes a computer to execute the processes of: accepting input of video images captured by a plurality of video cameras; causing at least one video image among the inputted video images to be displayed by a display device; registering one or more persons appearing in the video image displayed by the display device; and selectably displaying, when a person appears in the video image displayed by the display device, person images, which are associable to the person and which are related to one or more registered persons, in a vicinity of the video image.

“Moreover, as used in the present invention, the terms ‘unit’, ‘means’, ‘device’, and ‘system’ not only signify physical means but also include cases where functions of the ‘unit’, ‘means’, ‘device’, and ‘system’ are realized by software. In addition, functions of one ‘unit’, ‘means’, ‘device’, or ‘system’ may be realized by two or more physical means or devices, and functions of two or more ‘units’, ‘means’, ‘devices’, or ‘systems’ may be realized by one physical means or device.

“According to the present invention, an image processing system, an image processing method, and a program capable of re-identification of a person appearing in a video image with a simple operation can be provided.”

The claims supplied by the inventors are:

“What is claimed is:

“1. An image processing system comprising: a non-transitory storage device to store instructions; and one or more processors configured by the instructions to: accept input of video images captured by a plurality of video cameras; cause at least one video image among the inputted video images to be displayed by a display device; register one or more persons appearing in the video image displayed by the display device; and display a window overlapped on a video image in which a person appears, the window moving accordance with a movement of the person in the video image, and the window being displayed near the person in the video image such that the person in the video image is not within the window before or after the moving of the window, wherein the window comprises one or more person images which are respectively associable to the person on the video image and which are selected from the one or more registered persons.

“2. The image processing system according to claim 1, wherein when a person image from the one or more person images is selected, the one or more processors are configured by the instructions to associate a person corresponding to the person image and a person appearing in a video image displayed by the display device.

“3. The image processing system according to claim 1, wherein the one or more processors are configured by the instructions to display a blank image along with the one or more person images in the window and when the blank image is selected, a person appearing in the video image are newly registered when the blank image is selected.

“4. The image processing system according to claim 1, wherein when a similarity between a person appearing in the video image and one or a plurality of registered persons is lower than a threshold, the one or more processors are configured by the instructions to display the one or more person images of the persons in the window, whose similarity is lower than the threshold, so as to be separate from the person image of a person whose similarity exceeds the threshold.

“5. The image processing system according to claim 1, wherein the image processing system displays the one or more person images of the persons in the window, whose similarity between the person appearing in the video image and one or more registered persons are higher than those of other persons.

“6. The image processing system according to claim 1, wherein the one or more processors are configured by the instructions to display the person images showing a posture approximating that of the person appearing in the video image.

“7. The image processing system according to claim 1, wherein the one or more processors are configured by the instructions to display person images showing different orientations of a same person.

“8. The image processing system according to claim 1, wherein the one or more processors are configured by the instructions to change a position of the window in accordance with the movement of the person appearing in the video image.

“9. An image processing method comprising the steps of: accepting input of video images captured by a plurality of video cameras; causing at least one video image among the inputted video images to be displayed by a display device; registering one or more persons appearing in the video image displayed by the display device; and displaying a window overlapped on a video image in which a person appears, the window moving in accordance with a movement of the person in the video image, and the window being displayed near the person in the video image such that the person in the video image is not within the window before or after the moving of the window, wherein the window comprises one or more person images which are respectively associable to the person on the video image and which are selected from the one or more registered persons.
