OpenCV libraries distributed with openVINO do not support WEBP image format. Is there a good reson for this or it is an oversight? Are there any plans to enable this format in future?
There is a reason: reducing dependency number reduces maintenance and increases security.
Is this a popular image format? It is possible to enable webp image format support in future if there is a demand.
WEBP is quite a popular format supported by most web browsers and lots of libraries (https://en.wikipedia.org/wiki/WebP)
OpenCV can deal with WEBP images easily if enabled at the build time (it is a build option). Given that WEBP support was added to openCV more than 5 years ago I presume it is very well tested.
If enabled it would make use of OpenCV much easier on images collected from the internet (especially on Windows where converters are more limited).
