Background Image Placement Determination for Composite Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current photo composition applications face difficulties in creating automatic image compositions efficiently, often constrained by background artwork or composition algorithms, leading to slow and cumbersome processes.
Innovation Solution
A system and method for automatically selecting background image placement on a canvas and identifying areas for foreground images, ensuring that the informative zones of the background image are not occluded, while allowing for flexible composition on canvases of arbitrary dimensions, using data indicative of the informative zone and aesthetic considerations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic image composition is implemented, then creation efficiency is improved, but composition quality and aesthetics may deteriorate due to algorithmic constraints
Solution Approach 1:
The system pre-identifies informative zones in background images before composition, storing this information for later use in foreground image placement decisions, thereby enabling efficient automatic composition without sacrificing aesthetic quality
Solution Approach 2:
The patent applies different treatment to different regions of the background image by identifying and protecting informative zones (regions containing important visual information) while allowing flexible placement in non-informative areas, thus maintaining composition quality throughout the image
2Manufacturing precision
If background artwork constraints are applied, then composition aesthetics are improved, but flexibility and user freedom deteriorate
Solution Approach 1:
The background image is segmented into informative zones and non-informative zones, allowing the system to apply aesthetic constraints only where necessary (in informative zones) while leaving other areas free for flexible user placement
Solution Approach 2:
The system dynamically adjusts placement constraints based on the identified informative zones of each background image, changing the parameters of freedom versus constraint according to the specific aesthetic requirements of each composition context
3Manufacturing precision
If informative zones are protected from occlusion, then image content quality is improved, but available placement area for foreground images deteriorates
Solution Approach 1:
The system resolves the area conflict by operating in the dimensional space of zone classification, separating the background image into protected informative zones and available non-informative zones, thereby maintaining both content quality and placement flexibility through spatial differentiation

AI summary
A system and a method are disclosed that determine placement of a background image on a canvas and area for placement of foreground images. A system and method include receiving data indicative of an informative zone of a background image and computing an estimated foreground area on a canvas for each candidate placement of the background image on the canvas. The estimated foreground area is computed based on the data indicative of the informative zone and the number of images to be used as foreground images and does not include the informative zone. One of the candidate placements is determined as a selected background placement based on the computed values of estimated foreground area. A composite image can be generated from the background image positioned on the canvas according to the selected background placement and foreground images positioned outside of the informative zone.
