INCLUDED FILTERS Description
Visual inspection Visual analysis of the image and comparison with a reference image.
File Format Automatic inspection of most common parameters that could indicate a non originality of the image.
JPEG Structure Display and comparison of main JPEG markers.
Hex Viewer Integrated hexadecimal viewer with search and comparison capabilities.
Hex Strings Extraction of all textual information embedded into an image file.
EXIF Display and comparison of EXIF information and other embedded metadata.
JPEG QT Display and comparison of JPEG quantization tables and other compression parameters of main image and embedded thumbnail and preview. Internal cameras and software database with thousands of configurations and support for user generate databases.
JPEG HT Display and comparison of JPEG Huffman Tables of the main image, embedded thumbnail, and preview.
Social Media Identification Signature-based detection of images being downloaded from social media platforms.
Thumbnail Display of embedded thumbnail and preview images and their difference with the main image.
DCT Plot Analysis and comparison of the histogram of DCT coefficients and its Fourier transform for detecting multiple resaves of the image.
Correlation Plot Analysis and comparison of correlation periodicities in the image pixels to analyze the presence and consistency of demosaicing or interpolation effects.
JPEG Ghosts Plot Plot of the image with its recompressed version to identify signs of multiple compressions.
Histogram Analysis of the histogram of the image that can help to spot excessive intensity adjustment.
Color Space Analysis of the color space usage of the image in the HSV and Lab coordinates that can help spot excessive color adjustment.
Fourier Analysis of the image in the frequency domain to identity traces of screen recapture.
PRNU Identification Creation of a PRNU (sensor noise) reference pattern from a user supplied set of pictures and identification of the device that generated the image by comparison with the reference pattern.
Color Channels Analysis of single image channels in different color spaces (RGB, YCbCr, YUV, HSV, HLS, XYZ, Lab, Luv, CMYK).
Histogram Equalization Contrast enhancement that permits user to spot traces of manipulation.
ELA Identification of spliced areas of the image that have been compressed differently (error level analysis).
DCT Map Display of the image DCT values that can help to spot tampered uniform areas of the image.
Blocking Artifacts Detection of inconsistencies of compression blocking artifacts of the image due to image manipulation.
JPEG Ghosts Map Identification of manipulated areas of the image based on pixel-domain analysis of multiple JPEG compression.
ADJPEG Identification of manipulated areas of the image based on DCT-domain analysis of aligned double JPEG quantization artifacts (ADJPEG). Useful when a JPEG image is opened, locally changed (tampering with pixel, or pasting content from other image) and finally re-saved as JPEG without any global post-processing.
NADJPEG Identification of manipulated areas of the image based on DCT-domain analysis of non-aligned double JPEG quantization artifacts (NADJPEG). Useful when a large patch of pixels was pasted from a JPEG image into the suspect image followed by JPEG compression without any global post-processing.
Fusion Map Identification of manipulated areas of the image based on the joint analysis of JPEG Ghosts Map, ADJPEG and NADJPEG. Takes into account the local properties of the image to improve output map.
Correlation Map Identification of discontinuities in the correlation between pixels of the image.
Noise Map Display of inconsistencies in the noise level of the image.
PRNU Map Identification of inconsistencies in the PRNU noise of the image.
PRNU Tampering Automatic identification of tampered areas of the image by comparison with the PRNU reference pattern of the image.
LGA Identification of luminance discontinuities (luminance gradient analysis).
Clones Blocks Identifications of similar areas of the image that can be the result of cloning.
Clones Keypoints Identification of groups of similar points in the image that can be the result of cloning.
