3D Video Audio Enhancement via Depth Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Three-dimensional video and audio captured by mobile devices often have audio that does not correlate correctly with enhanced video, leading to a lessened playback experience due to the lack of synchronized audio modification with video enhancements.
Innovation Solution
A mobile computing device with a three-dimensional camera and microphone array that captures and stores three-dimensional video and audio, allowing users to select regions for audio enhancement by utilizing depth data to isolate and modify audio components, ensuring synchronized audio with video modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If three-dimensional video is enhanced by selecting and modifying specific regions using depth data, then video quality and user experience are improved, but the audio remains unmodified and does not correlate correctly with the enhanced video regions
Solution Approach 1:
The audio track is segmented into multiple audio components corresponding to different spatial regions in the three-dimensional video. Each audio component is associated with specific video regions through depth data analysis, allowing independent modification of audio to match video enhancements while maintaining overall audio-video synchronization
Solution Approach 2:
Different audio components are assigned different properties and modifications based on their corresponding video regions. The audio enhancement is applied locally to specific regions rather than uniformly across the entire audio track, enabling precise audio-video correlation matching the selective video enhancement
2Reliability
If the entire audio track is modified to match video enhancement, then audio-video correlation is improved, but audio quality deteriorates due to unnecessary modifications across all regions
Solution Approach 1:
The audio track is divided into distinct audio components corresponding to different spatial regions. Only the audio components associated with enhanced video regions are modified, while other audio components remain unchanged, preserving overall audio quality while achieving accurate audio-video correlation for enhanced regions
Solution Approach 2:
Instead of applying audio modification across the entire audio track, the modification is applied partially only to the specific audio components corresponding to enhanced video regions. This partial action approach maintains audio quality by avoiding unnecessary modifications to regions that are not enhanced in the video

AI summary
Technologies for localized audio enhancement of a three-dimensional video include capturing a three-dimensional video including depth data using a three-dimensional camera of a mobile computing device and receiving a three-dimensional audio associated with the three-dimensional video using a microphone array. A user may enhance localized audio by selecting a region of the three-dimensional image from the three-dimensional video. In response, the mobile computing device generates an audio component of the three-dimensional audio corresponding to the selected region based on depth data associated with the selected region. A user may subsequently enhance the audio component by, for example, increasing the volume of the audio component or increasing the clarity of the audio component. In this way, a user may focus the audio playback on a selected portion of the three-dimensional video, which improves the user's ability to listen and understand an individual, group of individuals, or region captured in the three-dimensional video.
