Last events section#

The “Last events” section displays detection and object (faces, bodies) recognition events, and records identification events using lists (Figure 5).

The section displays the last 30 events within the settings of handling policy for processing incoming images of the video stream, terminals, REST requests, etc. Receiving and displaying events is performed with minimal delays in near real time.

At the bottom of the screen, there is a “View events archive” button which leads to “Events archive” section

“Last events” section
Figure 5. “Last events” section

The filter icon (1), which is located on the right, hides the block with filtering settings. The page shows the following event data (2):

  • "Event image"
  • a photo image of the face from the video stream;
  • a photo image of the body from the video stream;
  • "Top Match"—the column is shown if the “Display top match” checkbox is active (3). If no matches are found for a photo from an event, then the column with the top match for this event will remain empty. The "Top match" includes:
  • reference photo images of the face and/or body;
  • value of similarity of the identified face with the reference in percentage terms and with the color coding of similarity thresholds:
    • similarity values below “low” will be marked in red;
    • similarity values between “low” and “medium” will be marked in yellow;
    • similarity values above “medium” will be marked in green.
  • "Match type"—the type of object (face or event), according to which the similarity of the identified face/body with the reference was found;
  • "External ID"—external identifier of the face, the field is shown if such an ID is available (for "Face" in "Match type");
  • "User data"—information from the database, linked to a person from the control (for "Face" in "Match type");
  • "List"—the name of the list to which the person is attached (for "Face" in "Match type");
  • "Date created"—date and time of fixing the event (for "Event" in "Match type");
  • "Source"—the name of the source that recorded the event at the time the event was created. Users can change the source name. Then the "Video stream" field will show the new name, and the "Source" field will show the original one (for "Event" in "Match type");
  • "Video stream"—the current name of the source that recorded the event, with a link to the real-time image of the stream (for "Event" in "Match type");
  • "Handling policy"—the name of the handler, according to which the reference photo image of the body was processed (for "Event" in "Match type").
  • "Event details" shows the available event data:
  • "Date of created"—date and time of event registration;
  • "Source"—the name of the source that recorded the event at the time the event was created. Users can change the source name. Then the "Video stream" field will show the new name, and the "Source" field will show the original one;
  • "Video stream"—the current name of the source that recorded the event, with a link to the real-time image of the stream;
  • "Handling policy"—the name of the handler, according to which the reference photo images of the face/body were processed;
  • "Metadata" [^1]—button for uploading arbitrary user data in JSON format, the filed is shown if such data was added to the event (for "Event" in "Match type").
  • Face attribute, if found:
    • "Gender"—gender based on face image;
    • “Age category”—the age of the detected person;
    • Deepfake check results, if such check was performed;
    • Liveness check results, if such check was performed
  • Body attributes, if found:
    • "Upper body colors"—an indication of the color of the clothes of the human body upper part;
    • "Lower body colors"—indicating the color of the human body upper part;
    • "Headwear"—the presence or absence of a headdress, if it is defined.
    • "Backpack"—the presence or absence of a backpack, if it is defined.

[^1]: All detailed capabilities and limitations of the "Metadata" field are specified in the "Administrator Manual" of LUNA PLATFORM 5 in the paragraph 6.9.4 "Events meta-information".

Last events filtering#

The Interface allows you to filter last events (2 in Figure 5) to find and display necessary events (Figure 6).

User can quickly find an event among the last 30, as well as set a limit for displaying new events on the screen.

Filter application to display the latest events: gender — male, age from 18 to 44
Figure 6. Filter application to display the latest events: gender — male, age from 18 to 44

When a user clicks on the icon (1 in Figure 5) on the “Last events” page, a menu with settings and filters opens. The number next to the icon shows the number of applied filters. A short description of the elements and parameters of the filter block on the “Last events” page is presented below (Table 1).

Color coding of temperature values:

  • abnormal temperature values will be marked in red;

Add filter by meta***

Allows you to fill in a set of blocks to create a filter by the "meta" field. The number of meta filters is unlimited. The following blocks are required to be filled in when creating a filter by meta:

  • Key—the full path to the required meta field connected with events.

  • Value—any valid value for the meta field.

  • Type—selection of the data type stored in this meta field. The data type displays available operators and converts values into the desired data type when sent to the API.

  • Operator—select operators for a given data type from the list. Operator type depends on the selected data type (for more details see LUNA PLATFORM 5 API, "get events" section)

The user selects one filter or a combination of filters and clicks on the “Filter” button for the applied filters to be applied.

To reset the applied filters, click on the “Reset” button.

The applied filters will affect the appearance of new events on the screen.

To collapse “Filters”, click on the filter icon on the right side of the screen.

Event details#

Click on an arrow button on the face or body from the event image (Figure 5) to open a page with detailed event data (Figure 7).

Detailed event data
Figure 7. Detailed event data

When an event contains data on the detection of both a face and a body, you can switch between these data on the page with event details. If an event contains detection data for only one object, such as a face, then there will be no detection data for another object.

The the page with event details consists of four blocks. The description of the elements of the page is presented below (Table 2).
