Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a cache system is used to store video information matching image-related data, then video service provision speed is improved, but system complexity increases
Solution Approach 1:
The system pre-extracts fingerprints from video frames and stores them in a cache system before user requests arrive. When an image is provided, the system can immediately query the cache for matching video information without performing real-time fingerprint extraction, thus improving service speed while managing complexity through advance preparation
Solution Approach 2:
A cache system acts as an intermediary layer between the image input and the video database. The cache stores pre-processed video fingerprint information and serves as a buffer that simplifies the interaction between the querying mechanism and the underlying video storage system, improving response speed while abstracting complexity
2Measurement precision
If fingerprint extraction is performed for every image query, then video matching accuracy is improved, but processing time increases
Solution Approach 1:
Video fingerprints are extracted and stored in the cache system in advance, before any user queries are processed. This preliminary fingerprint extraction eliminates the need for real-time processing during user interactions, maintaining high matching accuracy while dramatically reducing processing time for actual queries
Solution Approach 2:
The system performs fingerprint extraction selectively - only for video frames that are likely to be queried (stored in cache), rather than extracting fingerprints for all possible video content in real-time. This partial action approach maintains accuracy for relevant queries while avoiding unnecessary processing time
3Device complexity
If manual searching is required to find video content corresponding to images, then system complexity is reduced, but user convenience deteriorates
Solution Approach 1:
The system automatically performs the matching between images and videos without requiring user intervention. When an image is provided, the system autonomously queries the cache, extracts fingerprints if necessary, matches them with video content, and returns the relevant video information, thereby improving user convenience while keeping the automated process relatively simple
