Engineering Contradiction Analysis
1Reliability
If multiple kinds of motion estimation processing are performed in advance without considering analysis target and situation, then motion information with high likelihood can be obtained, but processing time increases significantly
Solution Approach 1:
The system changes the parameter of algorithm selection by adapting the choice of motion estimation algorithm based on the specific analysis target and situation. Instead of fixed pre-determined algorithms, the system dynamically selects appropriate algorithms matching the characteristics of the analysis target, thereby achieving high reliability without unnecessary processing time
Solution Approach 2:
The system implements dynamic algorithm selection where the motion estimation processing adapts to different analysis targets and situations. The algorithm choice is not static but dynamically adjusted according to the specific conditions, allowing the system to perform only necessary processing with high likelihood motion information
2Loss of information
If multiple analysis algorithms are executed without selective application, then comprehensive motion information is obtained, but processing efficiency decreases
Solution Approach 1:
The system applies different analysis algorithms to different analysis targets based on their specific characteristics. Each algorithm is locally optimized for its suitable application scenario, ensuring comprehensive motion information is obtained where needed while maintaining high processing efficiency by avoiding unnecessary algorithm execution in other contexts
