Image Forensics Studio
Inspect image signatures, dimensions, partial JPEG EXIF, hashes, color statistics, recompression differences and aligned image comparisons.
01 · Image intake & metadata
Dimensions, file signature, browser MIME, SHA-256 and partial JPEG EXIF tags.
02 · Preview & histogram
Channel means, distinct levels, luminance entropy and distribution.
03 · Recompression difference (ELA-like)
Re-encode JPEG, amplify pixel differences and download the visualization.
04 · Compare another image
Hash equality, dimensions and aligned pixel MAE when dimensions match.
05 · Metadata & JPEG internals
All EXIF/GPS tags, JPEG quality estimated from the quantisation tables, segment inventory, embedded thumbnails and trailing data. Also lists PNG/WebP chunks.
06 · Error level & noise consistency
ELA at a chosen quality and gain, plus a block noise-residual map. Regions whose noise or recompression error differs strongly from the rest are listed.
07 · Bit-plane viewer & LSB steganalysis
View any bit plane per channel; chi-square pairs-of-values test (Westfeld–Pfitzmann) per channel and as a sequential curve; LSB statistics and capacity.
08 · Copy-move (clone) detector
Finds near-identical textured blocks at different locations, a common trace of cloning/healing edits. Heuristic; repeated patterns in natural scenes cause false positives.
09 · Similarity lab (SSIM · PSNR · perceptual hashes)
Compares the image in panel 01 with the comparison image in panel 04. Perceptual hashes survive re-compression and resizing, so they find near-duplicates that SHA-256 cannot.
