Contour Extraction Apparatus for Image Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming techniques struggle to accurately extract areas intended by users, leading to erroneous detection of clear toner areas, which results in unnecessary area objects and inefficiencies in image processing.
Innovation Solution
An apparatus and method that includes a display unit, an operating unit, and a contour extracting unit to selectively display and extract area objects based on user-defined conditions, distinguishing between selected and unselected area objects, allowing for precise extraction of intended areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic contour extraction is performed on all area objects, then processing speed is improved, but measurement precision deteriorates due to erroneous detection of unintended areas
Solution Approach 1:
The system performs preliminary display of all extracted area objects to the user before final processing. This preliminary action allows the user to review and correct any erroneous detections, ensuring that only intended areas are selected for subsequent processing steps, thus resolving the contradiction between automated speed and detection accuracy
Solution Approach 2:
The system provides visual feedback by displaying extracted area objects on the display unit, allowing the user to verify correctness and provide correction input. This feedback loop enables the system to adjust its extraction results based on user confirmation, maintaining both processing efficiency and detection precision
2Measurement precision
If manual verification of extracted areas is implemented, then measurement precision is improved, but productivity deteriorates due to additional user tasks
Solution Approach 1:
The system performs self-service by automatically extracting and displaying area objects for user review, minimizing the manual effort required. The user only needs to review and correct obvious errors rather than manually verifying each area, thus maintaining high detection accuracy while preserving processing productivity
Solution Approach 2:
The system applies partial verification by displaying all extracted areas for review, which may seem excessive, but this comprehensive display actually reduces total verification time by allowing users to quickly identify and correct errors in a single view rather than iterative checking, thus improving both precision and productivity
3Ease of operation
If multiple area objects are displayed without distinction, then ease of operation is improved, but measurement precision deteriorates due to inability to identify selected areas
Solution Approach 1:
The system uses color changes or visual differentiation to distinguish selected area objects from unselected ones. This visual distinction maintains interface simplicity by using intuitive visual cues rather than complex controls, while simultaneously improving selection accuracy by making the selected areas clearly identifiable to the user
Data Source
AI summary
An apparatus for generating data includes a display unit that displays an area object the contour of which is extracted from an image to be processed by an image processing application, an operating unit that receives selection conditions for selecting an area object that is intended by a user out of the area objects displayed by the display unit, and a contour extracting unit that extracts a contour of an area object selected based on the selection conditions received by the operating unit. When the contour extracting unit extracts a contour of a selected area object, the display unit displays the selected area object and an unselected area object in a distinguishable manner.
