MobileNetV2 parameters: t,c,n,s
  t = expansion ratio (nhiddens per input channel) for bottleneck layers
  c = number of input channels
  n = repetition count of blocks (sum of n's = # layers)
  s = stride

Program included in this folder:

mb_demo1 loads an image and gives the top 5 classifications.

mb_demo2 loads several images and gives their feature vector
representations.

MobileNet.fsm runs the current camera image through the network and
prints the top 5 classifications.
