Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If template matching is performed to improve accuracy of virtual image positioning, then measurement precision is improved, but processing load increases
Solution Approach 1:
The patent divides the clothing image into multiple blocks and performs template matching only on a specific block containing the collar portion, rather than the entire image. This segmentation reduces the processing area and computational load while maintaining positioning accuracy for the collar region.
Solution Approach 2:
The patent applies different processing strategies to different regions of the image. Template matching is performed with high precision only on the collar block where accurate positioning is critical, while other regions use simpler positioning methods, optimizing the balance between accuracy and processing efficiency.
2Measurement precision
If template matching is performed across the entire image to improve accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the image processing into distinct blocks, with template matching applied only to the collar block. This reduces the overall system complexity by limiting complex processing to only the necessary region while using simpler methods elsewhere.
Solution Approach 2:
The patent extracts and isolates the collar block from the rest of the clothing image for specialized template matching processing. This extraction allows the system to apply complex algorithms only where needed, reducing overall system complexity while maintaining high accuracy for critical positioning.

AI summary
According to an embodiment, an image processing device includes a first calculator to calculate, when a photographic subject image is determined to satisfy a first condition, a first position of the clothing image such that the position of a feature area matches with the position of the feature area; a second calculator to calculate a second position of the clothing image in the photographic subject image such that the position of a feature point in the clothing image matches with the position of the feature point in the photographic subject image; a deciding unit to decide, when the photographic subject image is determined to satisfy the first condition, on the first position as a superimposition position, and decide, when the photographic subject image is determined not to satisfy the first condition, on the superimposition position based on the difference between the first position and the second position.
