Abstract

Noise characterization is important for several image processing operations such as denoising, thresholding, and HDR. This contribution describes a simple procedure to estimate the noise at an image for a particular camera as a function of exposure parameters (shutter time, gain) and of the irradiance at the pixel. Results are presented for a Pointgrey Firefly camera and are compared with a standard theoretical model of noise variance. Although the general characteristic of the noise reflects what predicted by the theoretical model, a number of discrepancies are found that deserve further investigation.
