Question to ask ich

1. Review of old work

• Optics: explaining the terms? Optical flow?
  
• Hardware: resolution, photos? illuminations
  
• Software: preprocessing, groove extraction, which part of groove is undulation.
  
• Common approach: RIAA EQ.
  
• Error introduced: Stotzer's blur
  
• Result: data amount, time cost
  
• Quality
• Fundamental difference with our approach
  

2. My workflow

• Optics: WLI
  
• Hardware:
  
• Software: alignment, polar/tertiary, preprocessing (detach/reattach), unwrapping, center correction, stereo.
  
• Common: edge detection, RIAA
  
• unique
• Error introduced: warp, center offset
  
• Result:
  
• Quality
