Video Close-Up Box Merging to Prevent Duplicate Participant Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In video communication, participants who are close to each other often appear in multiple close-up boxes, affecting the viewing experience and communication efficiency due to repeated appearances.
Innovation Solution
A method for determining close-up pictures involves recognizing close-up boxes for head objects, selecting and updating these boxes based on principal objects, and ensuring that each participant appears in only one box by deleting redundant boxes, while maintaining a rational layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If close-up boxes are constructed for each participant individually, then each participant can be clearly seen in their own box, but participants who are close to each other will appear in multiple boxes causing repetition
Solution Approach 1:
The patent merges close-up boxes by detecting when a second head object appears in a close-up box constructed for another participant. When detected, the second head object's close-up box is merged into the first participant's close-up box, preventing the second participant from appearing in separate repeated boxes while maintaining clear visibility of both participants in the merged box.
2Ease of operation
If close-up boxes are constructed for each participant individually, then each participant has their own dedicated box, but the device complexity increases due to managing multiple boxes
Solution Approach 1:
The patent implements dynamic close-up box management where the system initially constructs individual close-up boxes for each participant, then dynamically merges boxes when head objects are detected in multiple boxes. This dynamic approach maintains the simplicity of individual box construction while reducing the final number of boxes to display, optimizing both ease of operation and device complexity.
3Quantity of substance
If all close-up boxes are displayed, then complete information about all participants is shown, but the viewing experience deteriorates due to repeated appearances
Solution Approach 1:
The patent extracts and removes redundant close-up boxes from the display set. When a second head object is detected in a close-up box, the system extracts the second participant's information into the first participant's close-up box and removes the second participant's separate close-up box from the display, eliminating repetition while preserving complete participant information.

AI summary
Embodiments of the present disclosure disclose a method apparatus, device for determining a close-up picture and storage medium. The method includes: recognizing a close-up box to which each head object in the current frame of video stream data belongs, where each close-up box corresponds to at least one principal object, and the principal object is the head object that has been enclosed by the corresponding close-up box; selecting a close-up box from the close-up boxes as the current close-up box; determining that there is a second head object capable of being added to the current close-up box, determining the second head object as the principal object corresponding to the current close-up box, and deleting the close-up box constructed for the second head object; selecting a second close-up box to update the current close-up box as the selected second close-up box, and returning to perform an operation of when there is a second head object capable of being added to the current close-up box, until all current close-up boxes are traversed; and displaying the close-up picture of each close-up box in the video stream data. This method can solve a technical problem of repeatedly appearing close participants in multiple close-up boxes during close-up construction of video communication participants.
