Depth Single-Layer Encoding Without Texture Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies are unable to efficiently encode and decode depth information of video pictures as a single-layer bitstream, requiring the encoding and transmission of texture information, which limits their use in scenarios where only depth information is needed.
Innovation Solution
A method for encoding depth image sequences into a single-layer bitstream, including obtaining depth representation information, coding the depth image sequence based on this information, and encoding the depth map sequence and representation information in the bitstream, allowing for independent decoding and processing of depth information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing technologies encode depth information, then depth data can be transmitted, but texture information must also be encoded which increases processing complexity and data size
Solution Approach 1:
The patent extracts and encodes only the depth map sequence from the depth image sequence, separating it from texture information. This allows depth data to be transmitted independently without requiring texture information, directly resolving the contradiction by eliminating unnecessary data transmission while maintaining depth information integrity.
Solution Approach 2:
The patent segments the encoding process into distinct components: depth map extraction, depth map sequence encoding, and separate transmission channels. By dividing the original unified encoding process into separate segments for depth and texture, the system reduces overall processing complexity while ensuring complete depth information transmission.
2Adaptability or versatility
If multi-layer encoding is used for depth information, then comprehensive data is transmitted, but it requires both depth and texture information which is not suitable for depth-only applications
Solution Approach 1:
The patent implements dynamic encoding that adapts to application requirements. The system can selectively encode and transmit only depth map sequences when depth-only applications are detected, or combine with texture information when needed. This dynamic adaptation allows the same encoding framework to serve multiple application types while optimizing data transmission volume for each specific use case.
