Visual Similarity Duplicate Image Finder 7.5.0.1 Provides Support For .HEIC, .HEIF HEVC Encoded Images

Visual Similarity Duplicate Image Finder provides support for the High Efficiency Image File Format  – .heic and .heif images. These image formats are supported via external codec which should be installed prior to running the latest version. There are many HEIC codecs freely available on the Internet – just search for “heic codec” and install one on your system in order to enable the support for HEIC files. The “CopyTrans” heic codec is tested with VSDIF and working properly. The performance of HEIC file comparison depends on the installed codec and that is why a stable and fast implementation is a MUST. This new feature is available in the PRO and CORPORATE versions of VSDIF.

High Efficiency Image File Format

High Efficiency Image File Format (HEIF) is a file format for individual images and image sequences. It was developed by the Moving Picture Experts Group (MPEG) and is defined by MPEG-H Part 12 (ISO/IEC 23008-12). The MPEG group claims that twice as much information can be stored in a HEIF image as in a JPEG image of the same size, resulting in a better quality image.

The HEIF specification also defines the means of storing High Efficiency Video Codec (HEVC)-encoded intra images and HEVC-encoded image sequences in which inter prediction is applied in a constrained manner.

HEIF files are compatible with the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12) and can also include other media streams, such as timed text and audio.

HEIF image files are stored with filename extensions .heif or .heic.

Find duplicate WebP images – VSDIF 7.2.0.1

The latest version of Visual Similarity Duplicate Image Finder provides support for the WebP image format that was announced by Google as a new open standard for lossy compressed true-color graphics on the web. Current WebP implementation supports both lossy and lossless compression including alpha (transparency) channel. (Find more information on the WebP image format below)

The corrupt DNG images issue

We received complaints from our users who use Adobe Lightroom and DNG files, that VSDIF may crash on preview and/or scan of damaged DNG files. Our research on the topic fond many forum posts regarding DNG files and Adobe Lightroom – Google for: “dng+files+lightroom+corrupt”
We have not investigated those in details, but if you experienced issues with DNG files you should check those posts and the version of Adobe Lightroom that you are using. We have not analyzed those in details nor we claim that a relation between the damaged DNG files and Lightroom exists, but according to the search results above such possibility can not be excluded. The latest version of VSDIF can not load the DNG files as they are corrupt, but it will not crash.

A pre-release fix for the above issue was already provided to all our customers and it is included in this new version.

WebP – A new image format for the Web

Here is a quote from Google – ” WebP is a modern image format that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters and web developers can create smaller, richer images that make the web faster.”

Announced in 2010 the format aimed to produce smaller files of similar image quality to the popular JPEG scheme. Later Google announced WebP support for animation, ICC profile, XMP metadata, and tiling (compositing very large images from maximum 16384×16384 tiles). Google began to experiment with lossless compression and support for transparency (alpha channel) in both lossless and lossy modes; support has been enabled by default in libwebp 0.2.0 (16 August 2012). Google’s tests reveal that a conversion from PNG to WebP results in a 45% reduction in file size when using PNGs found on the Internet, and a 28% reduction in size when compared to PNGs that are recompressed with pngcrush or PNGOUT.

WebP Support

Google Chrome, Firefox, Edge, the Opera browser, and other tools and software libraries support natively WebP. Developers have also added support to a variety of image editing tools.
