JPEGsnoop is a free Windows application,
that examines and decodes the inner details of JPEG,MotionJPEG AVI and Photoshop files.
It can also be used to analyze the source of an image to test its authenticity.
Check out a few of the many possible uses for JPEGsnoop!
JPEGsnoop reports what digital camera or software was likely used to generate the image.
This is extremely useful in determining whether or not a photo has been edited/tampered in any way.
If the compression signature matches Photoshop,
then you can be pretty sure that the photo is no longer an original!
This type of analysis is sometimes referred to as Digital Image Ballistics/Forensics.
JPEGsnoop reports a huge amount of information,
including:
quantization table matrix(chrominance and luminance),
chroma subsampling,estimates JPEG Quality setting,
JPEG resolution settings,Huffman tables,EXIF metadata,Makernotes,RGB histograms,etc.
Most of the JPEG JFIF markers are reported.
In addition,you can enable a full huffman VLC decode,
which will help those who are learning about JPEG compression and those who are writing a JPEG decoder.
JPEGsnoop can now also parse and decode Photoshop files!
Other potential uses:
determine quality setting used in Photoshop Save As or Save for Web settings,
increasing your scanner quality,locating recoverable images/videos,decoding AVI files,
examining .THM files,JPEG EXIF thumbnails,extract embedded images in Adobe PDF documents,etc.
免费软件
Terms of Use
JPEGsnoop is free for personal and commerial use.
