Computational Perception [study realm]

There are some that you mentioned yourself.

• There are two eyes and two ears.
  
• Eyes have lens and pupil, ears have head, auditory cannal, eardrum...
  
• Eyes have photoreceptors that are sensitive to light, cochlea hair cells sensitive to sound.
  
• Both have ganglion cells, shaped like gabors.
  
• Eyes distinguish from left and right field of view, ears distinguish from lower and higher frequencies.
  
• Eyes have spatio-temporal receptive fields, ears have spectro-temporal receptive fields.
  
• Eyes have retinotopic map, ears have tonotopic maps.
  

You can also have auditory and optical effect analogies like optical blur which is caused by the accommodation of the lens can be analogous to the cone of confusion caused by the HRIR.

Isn't it actually quite amazing that both eye and ear split the input data in half? WE ARE BIOLOGICALLY ENCODED TO PARTITION THINGS INTO TWO POLARITIES ~~~~

Is it actually true that sound is split in a way that high frequencies is used to detect level difference while low frequencies is used to detect timing difference?

No, it is all speculation~~~ the truth lies in the secret of sacred geometry ohohohoho

It's a theory. High frequency has no information on timing difference because the wavelength is too small and peaks can shift in any direction to match in the coincidence detection structure. But we can still detect timing difference of high frequency for noise and impact sound because we can use the envelope of the sound.

What about level difference? Why low frequency doesn't have information on that?

Eh... the slides and exercises did not talk about it. :/

It's because people speculate that level diff is log scaled! IT'S THE POWER OF THE LOG THAT SPLITS THINGS INTO TWO~~~~ see we also use log in statistical classification. WHAT A SNEAKY FUNCTION

Oh, so at higher frequency, the ratio is smaller and the log value would have bigger changes, whereas at lower frequency, the ratio is larger and the log value would have little change. Thanks, evil-mashimaro <3 Let's study well together

No problem my sweet. But more precisely, you mean the slop of the log rather than the change of log. If all grad students write like you, I'm sure someone will kill himself. ohohohohoo

Seems like that someone is not coming back.

dat dude wont cuz he ll c m wright like sht ag'in

And you thought he would leave you talk like sht?

SHADOW~~~~ wait, you need to enter from the front door too...

so he dared to show up...

Spirit, did you do anything to make him come?

He just came...

...after reading my post.

datz haw mush he mis mi

TOMORROW IS THE END OHOHOHOHOOH
GOOD LUCK EVERYONE
