Bicubic Interpolation - Computerphile

Can you tell me what is Cardinal Interpolation please? Would it be possible to make a video on it?

The English subtitles are not complete.

I'm impressed of how much this man knows. Every time i'm googling some complex stuff explanation, i see his tutorials in the results. :D

Thank you for this. Now some of the other articles ive read actually make sense!

did you reticulate the splines...

Kyle brought me here...

IM PINCHING AND ZOOMING

Very nicely well-explained. Thank you!

AHHHHHHHHHHHHHHHHHH :)

Photoshop has "Bicubic sharper" and "Bicubic smoother" I don't know what the difference is, but I do know that the "auto" setting uses smoother when upsampling, and sharper when downsampling. In both cases it uses some sort of bicubic algorithm. It also has a plain "Bicubic" setting. Adobe says this is the "most precise", but the slowest.

In Photoshop you can explicitly tell it which algorithm to apply when resizing up or down, so in auto mode the code would use the resizing up/down to determine which algorithms is best for scaling an image up/down.

How to find boundary matrix of bicubc

Does it make a difference what order you interpolate in: Horizontal then vertical, rather than vertical then horizontal?

U are awesome thanks a lot

Hi sir, I want to ask you about bicubic convolution interpolation in image to addopt on pixel estimation on wide missing pixels. Is it possible to use 8x8 neighbour pixels to perform bicubic convolution interpolation? How about the kernel and the interpolation formula?

My respect for the engineers of Photoshop has increased 1000 times

Could you do biquintic interpolation

What is also interesting with respect to this technique is that CNN-based superresolution models perfrom significantly better if the training input has been downscaled using bicubic interpolation rather than cruder methods.
