Question

The output of an image sensor takes values between 0.0 and 10.0. If it is quantized by a uniform quantizer with 256 levels, what will be the transition and reconstruction levels?

Answer 1

The subject is input image processing or signal processing and quantization to produce output digitized signals.

We assume a uniform quantifier.

Transition levels or decision levels are 0, 10.0/256, 2*10/256, 3*10/256 ... 256*10/256.

Reconstruction levels are 5/256, 15/256, 25/256, 35/256, .... 10.0 - (10.0/2)/256.
