Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional watermarking and fingerprinting methods are used for video playback recognition, then recognition capability is provided, but processing complexity and computational burden increase
Solution Approach 1:
The patent extracts only the necessary visual features from video frames for recognition, rather than processing entire frames or using complex watermarking algorithms. This selective extraction of key visual elements reduces computational burden while maintaining recognition accuracy.
Solution Approach 2:
The system creates simplified representations or copies of video content features that can be processed more efficiently. Instead of analyzing original high-resolution video data, the system works with extracted feature copies that retain recognition information but require less computational resources.
2Measurement precision
If comprehensive image processing is performed to account for background interference, then recognition accuracy is improved, but processing time increases
Solution Approach 1:
The system performs preliminary processing of video frames by pre-identifying and extracting key visual features before recognition processing. This preliminary extraction of essential information reduces the complexity of subsequent background interference handling and speeds up the overall recognition process.
Solution Approach 2:
The patent applies different processing strategies to different regions of the video frame based on their importance. Critical regions containing playback position information receive more intensive processing to handle background interference, while less important regions are processed more simply, optimizing the balance between accuracy and processing time.
Data Source
AI summary
A method includes processing live image data captured by a camera associated with a first device. The live image data is displayed by the first device. A video displayed by a second device is viewable within the live image data displayed by the first device. The live image data is processed to identify a spatial position of the video displayed with respect to the camera associated with the first device within the live image data, and to identify a known frame of the video. The method also includes causing augmented imagery to be displayed by the first device in a display area of the first device within which the live image data is displayed concurrently with the video displayed by the second device. The augmented imagery is displayed in the display area of the first device based on the identified spatial position, and in response to the known frame.
