1Manufacturing precision
If global illumination rendering methods are used to create realistic medical images, then image realism and quality are improved, but the complexity of parameter selection and optimization increases
Solution Approach 1:
The system automatically optimizes GI rendering parameters by training a machine learning model to predict optimal settings based on dataset characteristics and task requirements. This eliminates the need for manual parameter tuning by users, as the system self-adjusts to provide optimized rendering parameters for different medical imaging scenarios.
Solution Approach 2:
The invention systematically varies and optimizes multiple GI rendering parameters (such as light source positions, intensities, and material properties) based on dataset-specific characteristics. The machine learning model learns the optimal parameter configurations for different imaging scenarios, enabling automatic adaptation to various medical imaging tasks without requiring expert knowledge from users.
2Measurement precision
If manual optimization of GI parameters is performed for specific datasets and tasks, then detection accuracy is improved, but the time and effort required increases
Solution Approach 1:
The system performs preliminary optimization by pre-training the machine learning model on a large dataset of rendering parameters and their corresponding detection outcomes. This preliminary action creates a knowledge base that can quickly recommend optimal parameters for new datasets without requiring time-consuming manual optimization, thus reducing the time and effort needed for each specific application.
Solution Approach 2:
The system implements a feedback mechanism where the machine learning model continuously learns from detection outcomes and adjusts parameter recommendations accordingly. By incorporating detection accuracy feedback into the training process, the system progressively improves its parameter optimization capability, achieving high detection accuracy while minimizing the time required for parameter selection.
