Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image recognition is performed using a machine learning model under specific conditions, then recognition accuracy is improved, but the system cannot evaluate robustness against environmental changes
Solution Approach 1:
The system performs preliminary actions by generating simulated images with various environmental conditions (illumination changes, weather effects, camera angle variations) before actual robustness evaluation. This allows the machine learning model to be tested in advance under diverse conditions without requiring real-world data collection for each scenario.
Solution Approach 2:
The system creates copies of original images through image processing operations to generate simulated images representing different environmental conditions. These copied and modified images serve as test inputs to evaluate model robustness without needing physical replicas or real-world scenarios for each condition.
2Adaptability or versatility
If multiple images under various environmental conditions are used for evaluation, then robustness assessment capability is improved, but system complexity increases
Solution Approach 1:
The image processing device performs multiple functions using a single system: it generates simulated images, applies image recognition operations, visualizes recognition results, and evaluates robustness metrics all in one integrated workflow. This multi-functionality avoids the need for separate systems for each task.
Solution Approach 2:
The system introduces simulated images as an intermediary between original images and robustness evaluation. These simulated images serve as a mediator that transforms single-condition input images into multiple-condition test cases without requiring direct manipulation of the evaluation process itself.
3Adaptability or versatility
If simulated images are generated through image processing operations, then evaluation under diverse conditions is enabled, but processing time increases
Solution Approach 1:
The system applies partial image processing operations that generate sufficient environmental variation for robustness evaluation without creating excessive or unnecessary transformations. The processing is calibrated to produce just enough diversity in simulated images to adequately assess model robustness.
Solution Approach 2:
The system maintains continuous useful action by efficiently chaining image processing operations, recognition operations, and visualization steps together. The workflow is optimized to minimize idle time between operations while ensuring each processing step contributes meaningfully to the robustness evaluation.

AI summary
Provided is an image processing device or method configured to enable a system developer or a system administrator to easily and visually check robustness of a machine learning model against various possible environmental changes on site to thereby build a system with high robustness. In the image processing device or method, a processor performs information processing operations which include, in response to a user's operation to designate an image processing condition, performing an image processing operation on an original image based on the designated image processing condition, generating a simulated image that reproduces an image captured in a specific situation, generating a heat map (status image) that represents a status of recognition of a detection target, and overlaying the heat map on the simulated image to produce a result image as a result of visualization, which is output as display information.
