Veiling glare and Dynamic Range measurement from two images Presentation
Stray light (veiling glare) degrades image quality by fogging important details in darker areas, but it can be challenging to […]
Logarithmic wedges: a superior design
We introduce the logarithmic wedge pattern, which has several advantages over the widely-used hyperbolic wedges found in ISO 12233 (current […]
Using images of noise to estimate image processing behavior for image quality evaluation

Correcting Misleading Image Quality Measurements
We discuss several common image quality measurements that are often misinterpreted, so that bad images are falsely interpreted as good, and we describe how to obtain valid measurements.
Describing and Sampling the LED Flicker Signal
High-frequency flickering light sources such as pulse-width modulated LEDs can cause image sensors to record incorrect levels. We describe a […]
Validation Methods for Geometric Camera Calibration
Camera-based advanced driver-assistance systems (ADAS) require the mapping from image coordinates into world coordinates to be known. The process of computing […]
Measuring camera Shannon information capacity with a Siemens star image
Shannon information capacity, which can be expressed as bits per pixel or megabits per image, is an excellent figure of […]
Verification of Long-Range MTF Testing Through Intermediary Optics
Measuring the MTF of an imaging system at its operational working distance is useful for understanding the system’s use case […]
