Hi I am a new learner of NI vision, please bare with me.
1. I am quite confused by the terms of light intensity and gray scale value of pixels. Can anyone explain the difference to me? Or are they totally same thing?
2. I am currently processing a Grayscale (I16) image file. The bit depth of the image is 12 Bits. But I saw someone used IMAQ Histograph with the Number of Classes set as 8192(13 Bit), don't know why.
Thanks, Jane

Hello Jane,
1. Correct, gray scale and intensity are the same thing.
2. The number of calsses one selects is a judgement call. By increasing or decreasing the number of classes the more or less granular the histogram becomes. Without some context I cannot speculate as to why someone would use 8192 classes.
