Image-based prediction of imaging and vision performance.

Area of Science:

• Computer Vision
• Image Processing
• Optical Engineering

Background:

• Performance estimation for imaging systems is vital in design and high-risk applications.
• Existing methods may lack accuracy or require system operation.
• Predicting performance pre-operation is essential for cost and risk mitigation.

Purpose of the Study:
