Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If machine learning is used to optimize image processing tasks, then image quality and processing performance are improved, but system complexity and computational requirements increase
Solution Approach 1:
The system segments the image processing task into multiple specialized neural network components: a stabilization processing unit for motion correction, an image compression unit for reducing data size, and an image expansion unit for super-resolution. Each unit is optimized independently for its specific function, allowing complex image processing to be achieved through coordinated simple components.
Solution Approach 2:
The Bayesian estimator serves multiple functions simultaneously: it optimizes the stabilization processing parameters, compresses images, expands image resolution, and integrates sensor data. This multi-functional approach reduces overall system complexity by consolidating what would otherwise require separate optimization systems.
2Reliability
If sensor fusion processing is applied to integrate multiple data sources, then consistency and reliability of processed data are improved, but processing time and computational load increase
Solution Approach 1:
The system performs preliminary synchronization and calibration of sensor data during the machine learning training phase. The Bayesian estimator pre-processes sensor fusion parameters and establishes coordinate transformations in advance, so that during actual operation, sensor data from multiple sources can be integrated rapidly without extensive real-time processing.
3Measurement precision
If Bayesian estimation method is used for machine learning, then optimization accuracy and adaptability are improved, but computational complexity and training time increase
Solution Approach 1:
The Bayesian estimator applies localized optimization to specific regions and parameters rather than globally optimizing all parameters simultaneously. The system focuses computational effort on critical parameters such as stabilization transformation matrices and compression coefficients, while using fixed or simplified models for less critical parameters, thereby reducing overall training time while maintaining accuracy where it matters most.
Data Source
AI summary
A signal processing apparatus includes: a data input unit to which image data is input; an output unit configured to output an output value based on the data input to the data input unit; an expectation feedback calculator configured to calculate a difference between an expectation based on the input data and the output value; and a Bayesian estimator to which information on the difference and information based on the image data are input and which is configured to perform machine learning in order to approximate the output value to the expectation based on the input information and to search for an optimum configuration.
