Composite Group Image Generation via Subgroup Blending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Photographing large groups of people is challenging due to scheduling difficulties, ensuring everyone is present and has a proper pose at the same time, and requiring significant space and proper lighting, which can be inefficient and impractical.
Innovation Solution
A method to generate a composite group image from subgroup images, using a system that accesses and processes images with a common background, determines boundaries, calculates shift factors, and blends the images to create a cohesive final image, allowing for the creation of a group photo without the need for all individuals to be present at once or in a large physical space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all people are gathered together at a single time and place for photographing, then a complete group image can be captured, but scheduling difficulties and coordination challenges increase significantly
Solution Approach 1:
The patent divides the group photographing process into multiple segments by capturing individual portraits separately rather than requiring all participants to be present simultaneously. Each person's portrait is captured independently and then computationally combined to form the complete group image, eliminating scheduling conflicts and coordination challenges.
2Reliability
If a large physical space is provided to accommodate all people, camera, lights, and background, then proper group photography can be conducted, but space requirements and resource consumption increase
Solution Approach 1:
The patent transitions from a two-dimensional physical space requirement to a computational solution by capturing individual portraits in separate locations and combining them digitally. This dimensional shift eliminates the need for large physical spaces, extensive lighting equipment, and complex camera setups while maintaining group image quality.
3Ease of operation
If multiple photographs are captured and blended computationally, then a cohesive group image can be generated without gathering all people, but image processing complexity increases
Solution Approach 1:
The patent uses computational copying by capturing individual portraits and replicating them in the group image context with appropriate positioning and blending. Each individual's portrait is copied and integrated into the overall group composition, allowing flexible capture without requiring all participants present while maintaining operational simplicity through automated processing.

AI summary
A method and device for generating a composite group image from subgroup images is provided. Subgroup images, each having a common background, are accessed. The boundaries of a subgroup area within each of the subgroup images is determined. At least one horizontal and at least one vertical shift factor is determined using the determined boundaries. An arrangement for the subgroup images based on the at least one horizontal and the at least one vertical shift factor is generated. The composite group image is generated by blending the subgroup images arranged in the arrangement.
