Solution Overview
Problem
Real-time image processing for feature identification is challenging without access to large computational resources, making it difficult to perform tasks such as therapeutic laser treatments efficiently.
Innovation Solution
A hybrid data processing approach combining real-time and non-real-time techniques, where initial image processing is performed at a slower rate and results are tracked across buffered frames using a faster tracking process, allowing for efficient feature identification and tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time image processing is performed to identify features within images, then treatment accuracy is improved, but processing speed deteriorates due to lack of large computational resources
Solution Approach 1:
The processing system is segmented into two distinct components: a non-real-time processing system that performs comprehensive feature identification with high accuracy using machine learning, and a real-time tracking system that follows identified features across frames. This segmentation allows each component to be optimized for its specific function without compromising the other.
Solution Approach 2:
Feature identification is performed in advance on a selected frame before real-time treatment begins. The non-real-time processing system identifies and marks features of interest ahead of time, creating a foundation for subsequent real-time tracking without requiring heavy computational resources during the actual treatment process.
2Manufacturing precision
If comprehensive image processing is performed to identify treatment locations, then treatment precision is improved, but treatment time increases
Solution Approach 1:
The system performs comprehensive image processing and feature identification in advance, before the actual treatment begins. By completing the computationally intensive analysis beforehand, the system ensures high treatment precision while minimizing the time lost during the treatment procedure itself.
Solution Approach 2:
Instead of repeatedly performing full image processing on every frame during treatment, the system creates a copy of the identified features and tracks them across subsequent frames. This copying approach maintains treatment precision while dramatically reducing processing time during the actual treatment.
3Measurement precision
If feature tracking is performed across all subsequent images, then tracking accuracy is improved, but computational resource requirements increase
Solution Approach 1:
The system extracts only the essential feature identification from a single frame using non-real-time processing, then removes the need for repeated comprehensive processing. By taking out the critical feature detection step and performing it once ahead of time, the system maintains tracking accuracy while significantly reducing computational resource consumption during real-time operation.

AI summary
Features can be tracked across frames. The features are first identified in an initial frame using an image processing technique which may take a relatively long time to complete, such as the length of several frames. When the features are being identified within the initial frame, subsequent frames are stored in a fast track buffer and once the features are identified in the initial image, the features can be tracked across the frames in the fast track buffer using a relatively fast process, such a one that is able to process the buffer at a higher frame rate than the frames are received at.
