Image Compositing Using Inscribed and Circumscribed Geometric Guides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing techniques fail to appropriately composite images with face or object areas into picture borders due to shape mismatches between the image and the border, leading to inappropriate sizing and positioning of the object within the composition target area.
Innovation Solution
An image processing apparatus that acquires target and template image data, specifies an object within the target image, calculates a size ratio between an inscribed and circumscribed figure in the template image, and adjusts the object's size to match the composition target area, ensuring the object contacts the inscribed figure and the outer edge of the adjusted area matches the circumscribed figure's outline.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an image including a face area is composited with a picture border using existing techniques, then the processing is simple, but the object may not be appropriately positioned or sized within the composition target area due to shape mismatches
Solution Approach 1:
The patent applies preliminary action by pre-defining inscribed and circumscribed figures within the composition target area before image compositing. These geometric guides are established in advance to determine the exact positioning and sizing of the object, eliminating the need for complex real-time adjustments during compositing operations.
Solution Approach 2:
The composition target area is segmented into multiple geometric zones: an inscribed figure (inner boundary), a circumscribed figure (outer boundary), and intermediate regions. This segmentation allows the object to be precisely positioned within the inscribed figure while maintaining proper proportions relative to the entire composition area, resolving positioning accuracy issues.
2Adaptability or versatility
If the composition target area has an irregular shape, then the design flexibility is improved, but the object cannot be appropriately sized and positioned to match the border shape
Solution Approach 1:
The patent embraces asymmetry by allowing the composition target area to have irregular, non-uniform shapes while maintaining precise object positioning. The inscribed and circumscribed figures are defined relative to the specific geometry of each composition area, enabling accurate object placement that adapts to asymmetric or irregular border shapes without sacrificing compositing accuracy.
Solution Approach 2:
The system dynamically adjusts geometric parameters of the inscribed and circumscribed figures based on the specific shape and size of each composition target area. By changing these parameters according to the border geometry, the patent achieves both shape adaptability and compositing accuracy across diverse template designs.
3Manufacturing precision
If the object size is not adjusted according to the composition target area, then the processing speed is maintained, but the object appears at inappropriate size or position in the composited image
Solution Approach 1:
The object image performs self-service by automatically sizing and positioning itself within the composition target area using the pre-defined inscribed and circumscribed figures as guides. The system calculates the appropriate scale factor and transformation parameters autonomously, eliminating the need for manual intervention or complex iterative adjustment processes, thus maintaining processing efficiency while achieving accurate sizing.

AI summary
An image processing apparatus configured having processor and a memory and configured to perform: calculating a size ratio between an inscribed figure inscribed in a composition target area in a template image and an area determined based on an object in a target image; setting a first area including the object to the target image based on the size ratio; and generating a composited image in which an image in the first area whose size has been adjusted based on the size ratio is composited in the composition target area, wherein the first area is set such that, when the image in the first area is superimposed on the composition target area, the object contacts with the inscribed figure and an outer edge of the first area matches a circumscribed figure circumscribed to the composition target area.
