What's currently the best way to enlarge an image with interpolation?
Are there some tools around which are better than others? -- Alfred Molon Olympus E-series DSLRs and micro 4/3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

| What's currently the best way to enlarge an image with interpolation?
| I looked into this at one time for software I was writing. From what I could gather, bicubic is the best method for enlarging. I think Adobe claims to have their own "secret sauce" method that's better. I don't know whether there's anything to their claim, but the algorythm is not available, in any case, so you could only find out if you're using PS/CS. There was an interesting webpage somewhere that showed sample images of a lizard that had been treated with various methods, but I can't seem to find that page now. In any case, it will all boil down to adding in extra pixels to enlarge the image. The only difference I know of is in how many neighboring pixels are taken into account to decide the color value of a given added pixel. |

But (probably) some softwares are better at preserving edge sharpness, from what I remember. Some special algorithms to recognise edges and reconstruct/resharpen them when resizing. I believe I read this somewhere, but I can't remember where. -- Alfred Molon Olympus E-series DSLRs and micro 4/3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

First, this is highly printer dependent. Second, Photoshop gives you plenty of options when it comes to image resizing. |
