Caffe Requests #22

Closed vgenty closed 8 years ago

vgenty commented 8 years ago

Thought I'd open a fresh issue with all requested features

  1. The original image image (loaded from ROOT file) is thresholded according to min and max. Hitting "replot" loads a new image from the ROOT file, thresholds it and sends to the screen. There is an intermediate layer that makes sure pixels do not overlap and cause false color. The original image is not mean subtracted, but thresholded. When the image goes down to caffe, it's mean is subtracted from the thresholded image. Is this ok? No, it depends on how you trained your network i.e.

    • threshold and mean subtract (from perhaps mean image of the thresholded image)
    • or mean subtract and then threshold

    this issue is unsolved by the viewer

  2. You can modify the channels individually on the viewer, the ones you don't modify don't currently get sent to caffe.
  3. Slide the box and find where network is maximized, or goes above some threshold

A pretty picture of fake neutrino image, then me removing neutrino, the network knew what it was! See the "score" at the bottom of the screen. Left is cosmic, right is nu

I copy and paste background on top of the nu, score flips
