这个技术很牛
大家上传一线相片试试, 分辨率不变, 效果相当, 体积剧减, 只能在线使用http://www.jpegmini.com 图像压缩算法么.... 果然不错 {:5_362:} 真的假的？ 牛{:5_370:} 这个不错 {:5_335:} 图片质量下降很明显…… kiro 发表于 2011-10-16 20:53 static/image/common/back.gif
图片质量下降很明显……
你是指它们网上的demo, 还是你自己上传的相片?
要不要发上来, 大家看看质量区别? 只是很实用罢了。技术上没啥牛不牛的 啥？不就是用photoshop把jpg文件像素不变的再存一遍，选择降低qualitaet吗，比如本来用12存的，改用个7存就小个五六倍了，肉眼也大致上看不出来，这技术不是早八百年就有了，现在倒持倒持，简化一下单独列出来就牛了？ {:7_433:} 类似PS的webjpg? sword 发表于 2011-10-17 09:55 static/image/common/back.gif

Siri早八百年前也有了, 对不对?
你觉得这技术 八百年前 就有了, 所以你买了Photoshop, 在花钱.
人家觉得这个技术咱可以不用Photoshop的, 所以人家被 like 3k, twitter 2k,在赚钱.

Technology
Overview
JPEGmini is a patent-pending photo recompression technology, which significantly reduces the size of photographs without affecting their perceptual quality. The technology works in the domain of baseline JPEG, resulting in files that are fully compatible with any browser, photo software or device that support the standard JPEG format.
JPEGmini is capable of reducing the file size of standard JPEG photos by up to 80% (5X), while the resulting photos are visually identical to the original photos. The JPEGmini algorithm imitates the perceptual qualities of the human visual system, ensuring that each photo is compressed to the maximum extent possible by removing redundancies, without creating any visual artifacts in the process. This enables fully automatic, maximal compression of photos with no human intervention required.
JPEGmini can be implemented in end-user devices such as cellular phones, cameras, and personal computers, to reduce storage requirements for photos, and reduce the time and bandwidth required for uploading the photos to online services. It can also be implemented in image-centric data centers, to reduce Total Cost of Ownership (TCO), including storage, bandwidth, electricity , and floor space.
Components
JPEGmini technology has two main components: The first is an image quality detector, which imitates the perceptual qualities of the human visual system, to determine the maximum amount of compression which can be applied to each individual photo without causing visible artifacts. The second is a unique JPEG encoder, which adapts the JPEG encoding process to the original photos, creating the most compact representation of the photos that is possible under the JPEG standard. Combining these two components enables JPEGmini to achieve an extremely high recompression ratio of up to 5x, or 80% reduction on digital photos, depending on their resolution.

siri早八百年前没有.八百年前那个叫语音输入.
photoshop这个技术早八百年前的确有了,还是ps的最基本功能.花没花钱我就不知道了,你说我是说花钱好还是不花钱好呢...anyway..
现在把这八百年前的技术单独拎出来的确做的很聪明,方便好用,也很受欢迎.也许这想法是牛的,但是技术本身不能称之为牛.

图上这司机怎么了? 介绍一个微软自带的，小而实用。
Resize Pictures Microsoft 安装后右点击图片就可使用，想多大多小都行。 sword 发表于 2011-10-19 00:07 static/image/common/back.gif

siri看上去不也就是语音输入吗， 但它能理解你的意思，这就是卖点，
同样， 用photoshop压缩我们需要自己确定压缩比的， 比如８０％， ６０％， 你不能对photoshop说， ＂给我尽量压缩！＂， 但jpegmini就是自己分析相片， 尽可能压缩， 但也不会强来， 我试过一张图片， 压完后是原来的８０％大小。 zpvip 发表于 2011-10-19 08:47 static/image/common/back.gif

呵呵, 和气第一, 这个网站也不是我的,随便推荐一下,正如你说的, 其实也就那么回事. zpvip 发表于 2011-10-19 12:01 static/image/common/back.gif

对，特喜欢这个版块的和气，是那种不矫情不拉帮结伙的和气，都是有智慧的好人，多切磋切磋才好玩。{:5_366:}
