Its incredible how high quality and well produced your videos are, not even to comment on the quality of your content and how you explain the ideas, thanks for sharing, i am grateful with the effort your give.
thank you so much for the very very nice videos. production quality is insane, you really have nailed down this setup. i have subbed to your channel, i am convinced i should go over all the material now ahah
Hi, how to make using wavelet transform image compression for live web camera ? Is there a resource for this ? github or videos ? can you help me ? please...
while computing the decomposition example I get this error referring to the pywt.coeffs_to_array command: 'expected a 3-tuple of detail coefficients'. Any help?
I was having the same issue. I had a index issue in my for loop. The line that is cutoff should read: for detail_level in range(n): coeffs[detail_level + 1] = [d/np.abs(d).max() for d in coeffs[detail_level+1]] Everything worked as shown for me after making that adjustment.
@@javiergutierrezoliet3124 I think the only other part that is cut off is specifying that output_format = 'wavedec2'. It was helpful to look at the pywt documentation (surprise surprise :) )
I believe the code isn't working anymore. Converting the coeffs to arrays and slices no longer functions. The PyWavelet documentation is also terrible.
tried doing compression on color image , but their are few pixels on the image scattered around my dogs nose , eyes and tongue in red, blue, and green colors.
The loud mouth sounds you make every now and then (e.g. around 6:10) are annoying. I don't mean to be rude, just saying that maybe you want to train that habit off. Otherwise great video. Especially liked the parts where you gave a real-world example of how these wavelets have basically changed image loading over slow connections. PS: Btw I had come across that dog when I read about SVD for my thesis. It was in some paper related to CV or so. Pretty amazing to see the owner in the video.

Wow, thank you!
I took a shot every time you said "kind of" and now I am hammered.
As always, great lecture. Simultaneously deep and accessible.
Glad you think so!
Professor Paul Loya @ Binghamton University also has written about fourier transforms on wave functions

Much appreciated!
These videos are better than ice cream. And I love ice cream.
Wow, in my family that is the highest form of praise!
is the code available somewhere?
THIS IS AMAZING THANK YOU SO MUCH FOR YOUR TIME AND EFFORT

@@brianknight6236 Thank you! did you get to the second example? another line is cut off...

شكرا جزيلا بروفيسور ستيف

We are so lucky that we can access these informations for free! Thank you
Nice videos..can you please make a detailed video on wavelet compression for jpeg2000. I tried wiki but getting lost in terminology like subbands, etc
Can I have the code please?
github.com/dynamicslab/databook_python
"Do you haz teh codez?" x^D
Sehr gut

Yeah same
@@shirishavissom129 i have noticed it happen with some images while others transform flawlessly.
@@shirishavissom129 i think we have to take the different number of coefficients for different channels. .. try it
Hey , It's showing an error somewhere. Could you just help me out with it?
I don't know why it's not taking me coefficients
Excellent! Where can I find the complete code?
Did you find the complete code?
Someone please tell me how to import the image. Cause I'm trying everything it's not happening.
WOW!!!!
