EI2025 Short Course: Information metrics for optimizing Machine Vision systems
2025-02-05 15:30 - 17:30 (America/Los_Angeles) | Hyatt Regency San Francisco Airport, 1333 Bayshore Highway, Burlingame, CA, 94010, United States
Description: A new set of metrics based on information theory promises to be superior to traditional MTF (SFR or sharpness) and noise for predicting machine vision system performance. We will introduce the new information metrics, which include Noise Equivalent Quanta (NEQ), camera information capacity, Ideal Observer SNR (SNRi – for the quality of object detection), and Edge location standard deviation (Edge σ – for the quality of edge location). We will cover the background of the new measurements, why they are more directly related to object and edge detection than traditional measurements, how to conveniently obtain them (primarily from standard slanted edge test patterns), how to interpret them, and how to design matched filters for optimum system performance.

Asia/Americas Office Hour: Correlating image quality with machine vision performance
2024-10-23 19:00 - 20:00 (America/Denver) | Zoom Office Hour Asia/Americas
The task of computer vision (CV) involves analyzing a stream of images from an imaging device. Some simple applications, such as object counting, may be less dependent on good camera quality. But for more advanced CV applications with limited control of lighting & distance, the quality of your overall vision system will depend on the quality of your camera system. This is increasingly important when an error made by the vision system could lead to a decision that impacts safety. Along with proper optimization of a CV model, ensuring that that model is fed by imagery from a high-quality camera system is critical to maximizing your system’s performance.

Tutorial by Norman Koren

Information Metrics for Performance and Optimization of Machine Vision Systems.
Norman Koren
Founder / CTO
We discuss the mathematical background and practical measurement techniques for a new set of image quality metrics that promise to be superior to MTF (sharpness) and noise as predictors of machine vision performance. The new metrics include Noise Equivalent Quanta (NEQ), Ideal Observer SNR (SNRi), and Edge location standard deviation (Edge σ). They can be measured from slanted edges as well as Siemens star and dead leaves (spilled coins) test chart images.¬ We cover

the origin and significance of information capacity, and its use as a fundamental metric for qualifying cameras,
the effect on measurements of common types of image processing, especially the bilateral filters found in most JPEG images,
the distinction between total information capacity and information capacity for contrast-limited patterns (typically 4:1 or 60% Michelson contrast slanted edges), which can be measured for a wide range of exposures,
obtaining the metrics for object detection (SNRi) and the object location (Edge σ),
the effects of sharpening and lowpass (noise-reduction) filtering, showing how excessive sharpening degrades performance,
design of matched filters to optimize SNRi and Edge σ for specific tasks, and tradeoffs for multiple tasks
progress in correlating the new metrics with standard machine vison performance metrics, such as Mean Average Precision (mAP) and Intersection over Union (IoU), which are related to object detection and location.

Leader SFR-Fit camera resolution measurement software measures MTF (Modulation Transfer Function). MTF indicates spatial frequency characteristics using multiple distortion and uniformity-corrected sine patterns that can be presented across one or more displays.
Conventional MTF measurement methods can have issues with black box camera systems that prevent the acquisition of the RAW or minimally processed image. If these systems have sharpening enabled, slanted edges can overstate MTF, especially at high frequencies.
The SFR-Fit measurement system can produce highly accurate measurements of automotive cameras is compatible with ultra-wide-angle lenses.
Calibrated Reference Camera for Camera Monitor System (CMS) testing with Leader SFR-Fit
By using SFR-Fit Ver2.4 and a calibrated reference camera, you can measure the MTF of a CMS electronic mirror.
