Quickstart

See the notebook tutorials.

TODO :

• : sequences shapes : the operators of opr module return sequence of different shapes depending on the operator used, while the genseq module always return 3d T/V/H sequences --> by default all should return same sizes (3d TVH ?), and a flag could allow to switch to the other representation (where shape depends on noise type)
• : lots of things could be done in the display module :
  • better 3d sequence viewer : add stats, sliders
  • classic python sequence viewer
  • same for spectrum viewer
  • allow differents scale for spectrums displays : normalized freq, sample#, real-space unit
• : masked : add numpy masked array support (for dead pixel for eg...)
• : add a "gaussian" checker to verify the histograms are approximately normal
• : non normal pixel exclusion : add a simple function to identify non-normal pixels, and mask them
• : add a module to read/load real tiff sequence
• : should define a class container for 3d sequence ?
• : should define a class container for noise analyser ?
• : implement all in a nice GUI
• : implement confidence intervals
• : add a list of hypothesis the model is based on
