Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If iterative calculation algorithm is used for image registration, then registration accuracy is improved, but calculation time increases significantly
Solution Approach 1:
The system performs preliminary actions by displaying deformation progress information and allowing users to correct corresponding points during the calculation process, rather than waiting for completion. This enables early intervention to improve registration accuracy without requiring the full iterative calculation to finish, thus reducing overall calculation time while maintaining precision.
Solution Approach 2:
The system implements feedback by continuously displaying deformation progress information to the user during the iterative calculation process. This allows users to monitor the registration progress and intervene with corrections to corresponding points based on observed deformation patterns, improving registration accuracy while potentially reducing the number of iterative steps needed.
2Measurement precision
If iterative calculation is performed for each corresponding points group, then registration precision is improved, but waiting time increases
Solution Approach 1:
The system displays deformation progress information before the iterative calculation completes, allowing users to perform preliminary corrections to corresponding points. This preliminary action enables users to improve registration precision by correcting obvious errors early, reducing the need for extensive iterative calculation and thereby reducing waiting time.
Solution Approach 2:
By providing continuous feedback through deformation progress display, the system enables users to assess registration quality during calculation and make targeted corrections. This feedback mechanism improves registration precision by allowing user intervention while reducing waiting time by preventing unnecessary completion of full iterative cycles when corrections are needed.
3Measurement precision
If manual correction of corresponding points is allowed during calculation, then registration accuracy is improved, but system complexity increases
Solution Approach 1:
The display unit serves multiple functions: it displays both the deformation progress information and provides an interface for user correction of corresponding points. This multi-functionality allows the system to maintain improved registration accuracy through user correction while minimizing system complexity by utilizing existing display infrastructure for multiple purposes rather than adding separate correction interfaces.

AI summary
An image processing apparatus includes: an obtaining unit configured to obtain corresponding points group information for associating a position in an image captured in a first deformation state with a position in an image captured in a second deformation state; a calculation unit configured to calculate deformation from the image captured in the first deformation state to the image captured in the second deformation state based on the corresponding points group information; a display control unit configured to display, on a display unit, deformation progress information of an image based on the deformation calculated by the calculation unit; and a correction unit configured to correct the corresponding points group information. The calculation unit calculates the deformation based on the corresponding points group information corrected by the correction unit.
