![]() ![]() This tool compares the original image to a recompressed version. Blocks that have been rejected because they do not have enough detail show up as black. Can be useful to tweak Minimal Similarity and Minimal Detail. Show Quantized ImageShows the image after it has been compressed. Maximal Image SizeThe maximal width or height of the image used to perform the clone search. Minimal Cluster SizeDetermines how many clones of a similar region need to be found in order for them to show up as results.īlocksize (2 n)Determines how big the blocks used for the clone detection are. ![]() Minimal DetailBlocks with less detail than this are not considered when searching for clones. Minimal SimilarityDetermines how similar the cloned pixels need to be to the original. If a lot of regions overlap the result can look white. Regions that are similar are marked in blue and connected with a red line. Note that this tool is a first attempt and not yet very refined. Has been manipulated using the clone tool. These can be a good indicator that a picture The clone detector highlights similar regions within an image. Histogram Equalization is the most robost option. Auto Contrast mostly keeps the colors intact, the others can cause color shifts. Histogram Equalization, Auto Contrast and Auto Contrast by Channel. MagnificationAlso known as the zoom factor.ĮnhancementThere are three different enhancements available at the moment. It does this by magnifying the size of the pixels and the contrast within the window. The magnifier allows you to see small hidden details in an image. You can use this application while offline. Just like a magnifying glass it can't tell true from false or good from evil,īut it might just help you to uncover the truth.Īlso absence of evidence is still not evidence of absenceĪnd Extraordinary claims require extraordinary evidence. It helps you to see details that would otherwise be hidden. You should think of forensically as a kind of magnifying glass. You can read a bit more about it in this blog post. It includes clone detection, error level analysis, meta data extraction and more. The privacy problem of Exif data can be avoided by removing the Exif data using a metadata removal tool.Forensically is a set of free tools for digital image forensics. For example, a whistleblower, journalist or political dissident relying on the protection of anonymity to allow them to report malfeasance by a corporate entity, criminal, or government may therefore find their safety compromised by this default data collection. Many users may be unaware that their photos are tagged by default in this manner, or that specialist software may be required to remove the Exif tag before publishing. For example, a photo taken with a GPS-enabled camera can reveal the exact location and time it was taken, and the unique ID number of the device - this is all done by default - often without the user's knowledge. Privacy and security: Since the Exif tag contains metadata about the photo, it can pose a privacy problem. if you upload an image of the Statue of Liberty, Google can extract the latitude-longitude (Geo co-ordinates) of the image and can return similar images that were taken near to that place matching the co-ordinates. You might know, Google Image search can find similar images like the uploaded ones using the GPS features of the EXIF data stored for the images. Nowadays, the place where the image was taken, is also stored in EXIF data in the form of latitude and longitude (GPS co-ordinates). Technical jargons of digital photography such as ISO, shutter speed, aperture can be stored in EXIF data. Using this, the images can be studied for any correction and then can be corrected in the next shot. But using EXIF data, photographers can get the detailed setting parameters of the camera while the image was being taken. Most of us know that digital cameras can store the picture name, data and time at which the photo was taken. Amateur photographers might not be aware of the EXIF data feature, but this feature is often used by professional photographers. EXIF is an important feature of the modern day digital cameras. EXIF data contains all the details about the image, camera settings and the conditions the image was taken. Free Online Tools Exif data viewer to read digital image propertiesĮXIF data (acronym for EXchangeable Image File) is the information about an image which is stored by almost all digital cameras. ![]()
