Bad Peggy searches for damaged JPEG files and validates and verifies pictures for truncation and other blemishes, which sometimes occur when such files are downloaded or restored from bad backups. It's fast, easy to use, and reliable in the analysis it does. It uses all available CPU cores too.
Twibright Registrator removes noise and can quadruple the resolution of a camera in software by matching several pictures together. It can be applied to remove noise, JPEG artifacts, rain, CRT stripes, and passersby. It can enhance night photos and provide the effect of long exposure in daylight. Pictures are matched by removing shift, rotation, zoom, and brightness changes. It features high performance bilinear interpolation, automatic adaptive corrective deconvolution, 32-bit float depth, photometrically linear space, and 16-bit depth PNG output.
