Unwanted Object Removal via Motion Vector Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When photographing with a camera device, unwanted moving objects often interfere with the desired image, requiring users to either re-photograph or manually remove them using image processing software, which can be cumbersome and imperfect.
Innovation Solution
An apparatus and method that analyze motion vectors of unwanted objects in preview frames, set a photographing interval to capture continuous frames, and automatically remove the unwanted objects, restoring the background image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user manually removes unwanted objects using image processing software, then the unwanted object can be removed from the photographed image, but the process is burdensome and time-consuming
Solution Approach 1:
The system automatically detects unwanted objects in the photographed image and performs removal operations without requiring manual user intervention. The control unit identifies objects based on motion vectors and autonomously executes the removal process, allowing the image processing system to serve itself rather than requiring user operation.
Solution Approach 2:
The patent replaces manual mechanical editing operations with automated computational image processing. Instead of users manually selecting and removing objects, the system uses algorithm-based object detection and removal techniques to automatically process the image.
2Reliability
If a user re-photographs the subject to avoid unwanted objects, then a cleaner image can be obtained, but the process is burdensome and environmental conditions may change unfavorably
Solution Approach 1:
The system extracts and removes unwanted objects from the photographed image while preserving the desired subject and background. By selectively removing only the unwanted elements rather than requiring a complete re-photography, the system maintains the original shooting conditions and environmental factors.
Solution Approach 2:
The system performs object removal as a preliminary or alternative action to re-photography. Instead of requiring users to retake photos when unwanted objects appear, the removal function is applied to the existing image, preventing the need for re-shooting under potentially different environmental conditions.
3Reliability
If manual removal of unwanted objects is performed, then the object can be removed, but the background image may not be perfectly restored
Solution Approach 1:
The system introduces an intermediary process that analyzes motion vectors and object characteristics to intelligently determine how to restore the background after object removal. This intermediary analysis layer enables more accurate background restoration compared to simple manual removal techniques.
Solution Approach 2:
The system uses feedback from motion vector analysis and object detection results to guide the background restoration process. By continuously analyzing the relationship between the unwanted object and the surrounding background, the system can more accurately reconstruct the background area where the object was removed.
