The Effect of Bit Depth on High-Temperature Digital Image Correlation Measurements

Figure 8

The relationship between image intensity, , Δ, MIG, , , and vs. exposure time for 12-bit images at otherwise baseline settings. (a) Three example images with the associated histograms; (b) plots of each metric vs. exposure time. Values and plots for 12-bit images hold the same trends as for 8-bit images (see Figure 7), but values are scaled in magnitude; the exception to this trend is , which is unchanged in the high-noise images and is only moderately larger in the low-noise images.
