JPEGsnoop-检测图片是否改动利器

Posted by derek on 七月 4, 2009 Leave a comment Go to comments

如何检测照片是否被PS过呢？或者说被修改了呢？你是否常常被一大堆人造美女图片所包围呢？或者说你对一些图片造假感到深恶痛绝却又不能分辨出来？好吧，不用担心，我们有帮手嘛……

JPEGsnoop就是一个不错的助手，它是一款免费绿色的软件，可以帮助您检测分析JPEG图片或动态JPEG图片是否被修改过，或者说是检测图片的真实性，唯一的遗憾就是软件支持的图片格式不多，并且软件不是那么人性化易用~~~

判定一共有4种情况：

class 1：图片被处理修改
class 2：图片很有可能被处理修改
class 3：图片很有可能没被处理修改
class 4：无法确定图片是否被加工还是原始的

需要注意的地方：windows系列的系统均可以运行，包括win7；JPEGsnoop支持的格式有些对于我们来说是不常见的，只支持基于动态JPEG编码的AVI、MOV格式。

我有点怀疑软件的准确性，如果添加了logo以后，也算是图片被修改了么？

补充：

JPEGsnoop is a free Windows application that examines and decodes the inner details of JPEG and MotionJPEG AVI files. It can also be used to analyze the source of an image to test its authenticity.

File Types Supported

JPEGsnoop will open and attempt to decode any file that contains an embedded JPEG image, such as:

.JPG – JPEG Still Photo
.THM – Thumbnail for RAW Photo / Movie Files
.AVI* – AVI Movies
.DNG – Digital Negative RAW Photo
.CRW, .CR2, .NEF, .ORF, .PEF – RAW Photo
.MOV* – QuickTime Movies, QTVR (Virtual Reality / 360 Panoramic)
.PDF – Adobe PDF Documents
上面有的格式对于我们来说是不常见的，只支持基于动态JPEG编码的AVI、MOV格式

* Note that video file formats (such as .AVI and .MOV) are containers, which can include video streams encoded in one of a wide variety of codecs. JPEGsnoop can only interpret this video footage if the codec used is based on Motion JPEG (MJPG).

The assessment line indicates one of four possible outcomes:

Class 1 – Image is processed/edited
Class 2 – Image has high probability of being processed/edited
Class 3 – Image has high probability of being original
Class 4 – Uncertain if processed or original

System Requirements

This application has been designed and tested to run on Windows XP and Windows Vista, but it should also work for Windows 95/98/NT/2000.LINUX users: JPEGsnoop apparently works on LINUX under wine
