Solution Overview
Problem
Existing rendering techniques face a trade-off between quality and speed, with high-quality rendering requiring significant processing resources and time, while lower quality but faster methods are inadequate for interactive, real-time applications.
Innovation Solution
A system that generates arbitrary views by transforming and merging existing high-definition images with minimal processing overhead, using a database of images with associated camera metadata to quickly produce high-quality outputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-quality rendering techniques are used, then rendering quality is improved, but rendering speed deteriorates
Solution Approach 1:
The system pre-renders multiple views of a scene and stores them in a database before they are needed. When an arbitrary view is requested, the system retrieves pre-computed views and merges them rather than rendering from scratch. This preliminary preparation enables fast retrieval and merging operations that maintain high quality while achieving real-time performance.
Solution Approach 2:
The system creates and stores multiple copies of scene views from different perspectives in a database. These pre-computed view copies can be quickly retrieved and combined to generate arbitrary views without performing full rendering operations at query time, thus maintaining quality while improving speed.
2Productivity
If real-time rendering is implemented, then rendering speed is improved, but rendering quality deteriorates
Solution Approach 1:
The system merges multiple pre-computed views that were rendered at high quality to generate arbitrary views in real-time. By combining information from multiple high-quality source views stored in the database, the system produces high-quality output without performing slow full rendering operations at query time.
Solution Approach 2:
The system uses pre-computed views stored in a database as intermediary representations. These intermediaries contain rendered scene information that can be quickly retrieved and transformed into arbitrary views, serving as a bridge between offline high-quality rendering and online real-time requirements.
3Manufacturing precision
If traditional rendering methods are used, then rendering quality is improved, but computational resources increase
Solution Approach 1:
The system performs computationally intensive rendering operations in advance and stores the results. When arbitrary views are needed, the system retrieves pre-computed views and performs lightweight merging operations, dramatically reducing the computational resources required at query time while maintaining high quality output.
Solution Approach 2:
The system stores multiple copies of rendered views in a database, avoiding the need to re-compute expensive rendering operations. These pre-computed copies can be retrieved and merged with minimal computational overhead, reducing energy consumption while preserving rendering quality.

AI summary
A machine learning based image processing and generation framework is disclosed. In some embodiments, depth values of an object or asset in a received input image are at least in part determined using a machine learning based framework that is constrained to a known prescribed environment. Determined depth values facilitate generation of other views of the object or asset.
