Unlock The Secrets Of Image Quality: Demystifying Contrast To Noise Ratio (Cnr)
Contrast to noise ratio (CNR) is a crucial parameter in image quality assessment, measuring the ratio of contrast (variation in brightness levels) to noise (unwanted variations). CNR quantifies image clarity by determining the visibility and detail of structures within an image. Its impact on image quality affects diagnostic accuracy in medical imaging, scientific research, and forensic investigations. By understanding CNR and its complementary perspectives (dynamic range and SNR), one can enhance CNR through contrast enhancements to optimize image fidelity and ensure accurate interpretation.
