Hi !
Dont know if i should write my message in this topic but hey i am new
(ok, i am just lame , hmm)
I am upsizing (800x600 -> 1024x768) images and in ACDsee i can select resize filters. Does anyone know anything about next few filters:
bell, box, bicubic, b-spline, mitchell, lanczos, triangle.
Example: i know B-spline is derived through N convolutions of box filter B0, so B1 = B0 * B0, B2 = B0 * B1 = B0 * B0 * B0, ... The core (i think is also called kernel or something like that) is the same as bicubic core, that is

OK, that was xample
So, can you help me !?
Tnx, for your post, bye !
Filtering pictures
HSV nad HSL color depth
Hi !
This has nothing to do with filtering pictures (just didnt wanna open new topic).
Can anyone tell me what color depths are in HSV / HSL color models ?
(just cant find it with google)
Example: RGB supports 1,4,8,15,24. 32 not supported.
Tnx for viewing and all posts.

Re: Filtering pictures
It depends on the implementation of these filters and on the used image, which ones produces the best results. From my experiences with other tools, I would say that bicubic, mitchell or lanczos will probably produce the best results. Just use all three and see which one produced the best result. Maybe you won't even see a real difference.gac wrote: I am upsizing (800x600 -> 1024x768) images and in ACDsee i can select resize filters.

Color models aren't linked to certain color depths. You can have HSV/HSL in 8bit, 16bit or even 32bit color depths.gac wrote: Can anyone tell me what color depths are in HSV / HSL color models ?
