Suppose I have found a picture for a seiyuu that ANN does not yet have a picture for, but while it does display the person's face and is of relatively good quality, it is too small to make into a good 100x100 mug shot image. Should I bother submitting this, and if yes, should I stretch it from 50x50 to 100x100 or just crop a larger area of the photo (which does contain other people as well)?

If this is the only image you can find of said person, it would probably be better to stretch the image. As long as it's still moderately good quality, it would be fine.

All right, I'll do so. If you don't like it, of course, you can obsviously just reject it. With any luck, a larger picture of this person will become available soon enough.

If you want to enlarge a picture, be sure to choose the proper resampling / interpolation algorithm (if available). Most image editing software offer bilinear interpolation. FastStone Photo Resizer (freeware) provides 11 different resampling filters, and the default Lanczos resampling provides excellent results. DO NOT use nearest neighbor.

I used the Bilinear option.
For reference, here's the guy in question. |

Actually bilinear interpolation is pretty crappy for enlarging a picture. Try bicubic interpolation if available, or even better use a Lanczos filter. ANN thumbnails are generated by a Lanczos filter because it creates sharp images when shrinking (better than bilinear interpolation thumbnails which are a little fuzzy) and pretty serviceable images when enlarging (which sometimes happens when the source image is too small).

Well, to be honest, I'm no graphics wizard. I've submitted my thumbnail, but if you would like to make a better thumbnail for Daisuke Kirii, here's a link to where I found the original picture.

You read Traditional Chinese websites from South Africa? Wow.
 The link is not working due to preventing hot-linking / picture stealing, but I got the page from your submission record.
I made a comparison chart for the three types of interpolation mentioned above. The chart itself is a .bmp file so there's no compression / distortion. 
From left to right: original 50 x 50 picture magnified 200%, bilinear, bicubic, Lanczos. Compared to bilinear, both bicubic and Lanczos gave sharper images with slightly more noise. The difference between the latter two is almost unnoticeable. |

Traditional Chinese? Maybe I'm misunderstanding something, but that site looked pretty much Japanese to me (I mean, I could read bits of it!).
 Anyway, it looks like the bilinear one came out the best.

The page is composed of mostly the transcript of the radio show (thus in Japanese), but the comments and notes were all written in Traditional Chinese. Just visit the root page of that site; the webmaster stated it quite clearly on the top banner, as well as all the news items.
Em, well, if you insist.

Ah, yes! Now that I look at it again, I can see that. Proof that I know nothing of traditional Chinese and just went there to get the photo and nothing else.
Oops... Was that a bad answer? How embarrassing. Proof that I know nothing of graphics manipulation. |
