Spilled Coins Charts for Imatest LED Light Sources

The Imatest Spilled Coins chart is designed to measure texture sharpness. It has offers nearly perfect scale-invariance, which improves the accuracy and robustness of measurements, as well as gray regions to the left and right of the chart that facilitate noise removal.

The Imatest Spilled Coins Cross test chart uses cross-correlation calculation texture metrics to provide improved stability for images with nonlinear noise reduction. Users can now more accurately differentiate between noise and texture. Random/Dead Leaves Cross, which runs under the interactive Rescharts interface, measures SFR (Spatial Frequency Response) or MTF (Modulation Transfer Function) from these patterns
