There are many sharpening software out there, but which one perform the best? One basic rule, you really can\'t get what is already out there~~

1) Photoshop bicubic x2

[upload=gif]UploadFile/2005-5/200551015441671.gif[/upload]

The result is pretty good, the picture is slightly burred at the edge, otherwise the image is pretty sharp. No specific JPEG artifact appears; the contract is also maintained.

(结果相当好, 图片边缘轻微地burred。具体JPEG 人工artifact 没出现)

2) Photoshop bicubic sharpener x2

Exactly the same as above, the only difference might be the color depth; no significant changes has been made compare to the above image.

(大致同样)

3) Genetic Fractial v4

The image is indeed sharper and more sophisticated!! But take a look at the green areas, there are many noise exist in the area. Basically you can simply achieved this level by using USM in the photoshop.

(图象的确是更加锋利!! 但看一看绿色区域, 那里有许多噪訊存在。您基本上能简单地达到了这个水平由USM 在photoshop 。)

4) S-Spline (photozoom) pro photoshop v1.9

The image is sharper, and it also give you a cropped image~~!! This is not good because you will lose 1% of your original data. Many people in swcool said this program is amazing, but I personally don\'t think there is any advantage over other method above.

(图象更加锋利, but its 99% cropped~~!! 这不是好的因为您将丢失1% 您原始的数据。许多人在swcool 说这个filter 是令人惊讶的, 但我不认为有任一好处在其它方法上面。)

5) Lancoz (photozoom) photoshop plugin

[upload=gif]UploadFile/2005-5/2005510155717144.gif[/upload]

Greater color rendition, slightly sharper than bicubic, otherwise the method is pretty much the same~~

6) conclusion:

There are many enlargement programs out there, but certainly there are no "magic" tools. The math used on those programs are basically the same. "You can\'t really create what is not out there" quoted from a member right here.

(您基本上不需要任何扩大工具除photoshop 之外) (CS or CS2 only)

Using photoshop bicubic is all you need~~:p

Can someone help me to translate to chinese??

怎么写英文，看不懂

TTdown has both genetic fractal v4 and photozoom pro~~ :p [em07]

Sorry my computer system is English

理解不能发中文帖子，但是....可以稍微检查一下语法。

另外，XP的语言功能应该很强了，不知道楼主用的什么版本

语法 alittle bad, but some are just english slang~~ sorry :p

I added some chinese description~

正面的论述和分析已经做过很多不再重复了。假如放大能有“滤镜奇迹”，Adobe 为什么不把那个技术买下来，难道 Adobe 买不起？除非对方是它的死敌，可死敌为什么要给 PhotoShop 做滤镜？

凡人大多希望有奇迹，越无知的人越愿意相信号称的奇迹。基本上，相信“无损放大”奇迹的和相信 FL 功的是同一类人。

Besides, what adobe buy (买) is what really useful:

Photoshop CS2 Add: (1) Noise reduction (噪訊), (2) Lens Correction (變形): prove that these tools are useful for "photographer"

Maybe later we will see noise image vs. adobe noise reduction, or panoTool vs. adobe panotool ( I think adobe steel panotool because panotool is free)

I\'m going to 旅行 so I won\'t go online often this summer
