Stereo Suitability Scoring for 3D Video Frame Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for converting 2D video to 3D stereo images are inefficient, as they often require user input or fail to effectively identify suitable frames for stereo representation, lacking a systematic approach to produce high-quality alternate viewpoint images from captured videos.
Innovation Solution
A method that involves receiving a digital video, calculating stereo suitability scores for images, selecting candidate images based on these scores, and producing stereo images by combining suitable images to create a pair of images from different viewpoints, allowing for effective 3D perception without requiring user input for every frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic 2D-to-3D conversion is implemented without user input, then processing efficiency is improved, but the quality of stereo image selection deteriorates
Solution Approach 1:
The system automatically evaluates and selects stereo candidate images using computational algorithms that assess stereo suitability scores, eliminating the need for manual user input while maintaining quality through objective metrics based on image analysis and stereo geometry principles
Solution Approach 2:
The system transforms 2D video frames into stereo images by modifying geometric parameters and introducing synthetic depth information through computational methods, enabling automatic conversion while preserving visual quality through parameter optimization
2Reliability
If all video frames are processed for stereo conversion, then completeness is improved, but computational complexity and time consumption worsen
Solution Approach 1:
The video sequence is divided into discrete frames that are independently evaluated for stereo suitability, allowing selective processing of only those frames that meet quality thresholds, thereby reducing overall computational time while maintaining completeness of the stereo image set
Solution Approach 2:
Instead of processing every frame, the system applies partial processing only to frames that exhibit suitable characteristics for stereo conversion, identified through automated evaluation metrics that assess motion, depth cues, and visual quality
3Measurement precision
If stereo suitability scoring is implemented for each image, then selection accuracy is improved, but device complexity worsens
Solution Approach 1:
The system employs quantitative parameters such as stereo suitability scores that objectively measure image characteristics, transforming subjective quality assessment into measurable metrics that improve selection accuracy without requiring complex manual evaluation systems

AI summary
A method of producing a stereo image from a digital video includes receiving a digital video including a plurality of digital images captured by an image capture device; and using a processor to produce stereo suitability scores for at least two digital images from the plurality of digital images. The method further includes selecting a stereo candidate image based on the stereo suitability scores; producing a stereo image from the selected stereo candidate image wherein the stereo image includes the stereo candidate image and an associated stereo companion image based on the plurality of digital images from the digital video; and storing the stereo image whereby the stereo image can be presented for viewing by a user.
