Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional contour extraction processing lacks efficiency in determining the processing range, which hinders the effective application of special color ink printing technologies.
Innovation Solution
An information processing device with a receiving unit for user-specified position information, a processing range determination unit that sets a closed area based on the received positions within a threshold distance, and a contour extraction unit to extract the object's contour within the determined range.

Engineering Contradiction Analysis
1Productivity
If conventional contour extraction processing is used without position specification mechanism, then the processing can be performed, but the work efficiency is low and the processing range determination is cumbersome
Solution Approach 1:
The system automatically determines the processing range by detecting when the user's specification position returns to or near the start point, eliminating the need for manual range definition. The contour extraction unit autonomously identifies the closed area and sets the processing range without requiring additional user input or manual polygon drawing.
Solution Approach 2:
The system preliminarily tracks the user's position specifications and automatically closes the polygon when the return condition is met, preparing the processing range in advance before the actual contour extraction begins. This preliminary automatic range determination saves time during the extraction process.
2Manufacturing precision
If manual polygon drawing is used for contour extraction, then the processing range can be defined, but the operation becomes complex and time-consuming
Solution Approach 1:
The system automatically generates the closed polygon by tracking user position specifications and detecting when the return condition is satisfied. The processing range determination unit autonomously creates the polygon boundary without requiring the user to manually draw or specify complex polygon vertices, simplifying the operation while maintaining accuracy.
Solution Approach 2:
The system provides feedback by monitoring the user's position specifications in real-time and automatically closing the polygon when the return condition is met. This feedback mechanism guides the user through a simple specification process while the system handles the complex polygon formation and range determination automatically.

AI summary
An information processing device includes a receiving unit, a processing range determination unit, and a contour extraction unit. The receiving unit receives specified position information that indicates a position specified by a user with respect to a target image. The processing range determination unit determines, when a distance between a start point position that indicates a start point of positions indicated by the specified position information, and a position indicated by the latest specified position information is a threshold or less, a closed area obtained based on a history of the received specified position information as a processing range. The contour extraction unit extracts a contour of an object in the processing range.
