Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If handwriting recognition is performed directly on overlapping handwriting information, then processing speed is maintained, but recognition accuracy deteriorates due to incorrect recognition of overlapping elements
Solution Approach 1:
The patent segments overlapping handwriting information into separate handwriting elements by detecting overlap regions and separating them into individual handwriting objects. This segmentation allows each handwriting element to be recognized independently, improving recognition accuracy while managing processing complexity through systematic division of the recognition task.
Solution Approach 2:
The patent performs preliminary separation of overlapping handwriting elements before recognition. By detecting overlap and separating handwriting elements in advance, the system prepares cleaned, non-overlapping handwriting data for the recognition process, thereby improving accuracy without significantly increasing overall processing complexity.
2Measurement precision
If overlapping handwriting elements are separated by adjusting positions, then recognition accuracy is improved, but processing time increases due to additional separation operations
Solution Approach 1:
The patent performs handwriting separation as a preliminary step before recognition by detecting overlap regions and adjusting positions of overlapping elements. This preliminary separation ensures that subsequent recognition operates on clearly separated handwriting data, improving accuracy while minimizing time loss through efficient overlap detection and separation algorithms.
Solution Approach 2:
The patent replaces complex mechanical or manual separation processes with automated image processing and pattern recognition algorithms. By using computational methods to detect overlap and adjust positions, the system achieves accurate separation with reduced processing time compared to traditional manual or mechanical approaches.

AI summary
An image processing apparatus includes a reception unit, a determination unit, a handwriting separation unit, an image generation unit, an image recognition unit, and an output unit. The reception unit receives handwriting information. The determination unit determines whether first handwriting indicated by first handwriting information and second handwriting indicated by second handwriting information overlap each other on the basis of the handwriting information. The handwriting separation unit separates the first handwriting from the second handwriting by changing a first/second handwriting position in the first/second handwriting information when the determination unit has determined that the first and second handwriting overlap each other. The image generation unit generates an image from handwriting information obtained through the separation, and information regarding handwriting that has been determined not to overlap other handwriting. The image recognition unit recognizes the generated image. The output unit outputs the recognition result.
