Document Aspect Ratio Adjustment with Object-Aware Trimming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document editing methods fail to ensure that objects are fully contained within the image arrangement region when changing the aspect ratio, often resulting in partial cutting off of objects during resizing.
Innovation Solution
An information processing apparatus with a reception unit for aspect ratio changes, an adjustment unit for resizing the document and image arrangement region, a control unit for trimming images, and a display control unit to manage the resized images within the adjusted region, using deep learning for object detection and various trimming methods to ensure objects fit within the new aspect ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the aspect ratio of the document is changed and the image arrangement region is adjusted accordingly, then the document adapts to the new size, but objects may be partially cut off at the trimming position
Solution Approach 1:
The system performs preliminary detection of objects in the image before trimming occurs. By identifying object positions and boundaries in advance, the system can calculate multiple trimming position candidates that ensure objects are not cut off, thus resolving the contradiction between adapting to new aspect ratios and maintaining precise object positioning.
Solution Approach 2:
The system dynamically adjusts trimming positions based on detected object locations. Instead of using fixed trimming positions, the system calculates multiple candidates and allows selection based on object placement, enabling the trimming process to adapt dynamically to different images and their content, thereby preventing object cutoff while maintaining aspect ratio flexibility.
2Reliability
If multiple trimming position candidates are calculated based on object detection, then objects can be preserved in the image, but the complexity of the trimming process increases
Solution Approach 1:
The system segments the trimming process into distinct stages: object detection, candidate position calculation, and final selection. By dividing the complex trimming process into these manageable segments, the system can reliably preserve objects through systematic analysis while keeping the overall process organized and controllable, thus resolving the contradiction between reliability and complexity.
Solution Approach 2:
The system incorporates feedback mechanisms where object detection results directly inform the calculation of trimming position candidates. The detected object positions provide feedback that guides the generation of appropriate trimming candidates, ensuring objects are preserved while the feedback loop maintains process efficiency by focusing calculations on relevant regions.
