OpenCV vs Gumlet: What are the differences?

What is OpenCV? Open Source Computer Vision Library. OpenCV was designed for computational efficiency and with a strong focus on real-time applications. Written in optimized C/C++, the library can take advantage of multi-core processing. Enabled with OpenCL, it can take advantage of the hardware acceleration of the underlying heterogeneous compute platform.

What is Gumlet? Optimized image delivery made simple. It is an image optimization tool for websites and mobile apps. It detects the device size of your visitor, optimizes images on-the-fly and delivers them via CDN.

OpenCV and Gumlet can be primarily classified as "Image Processing and Management" tools.

Some of the features offered by OpenCV are:

• C++, C, Python and Java interfaces and supports Windows, Linux, Mac OS, iOS and Android
• More than 47 thousand people of user community and estimated number of downloads exceeding 7 million
• Usage ranges from interactive art, to mines inspection, stitching maps on the web or through advanced robotics

On the other hand, Gumlet provides the following key features:

• Automatic image resize
• Automatic format conversion
• WebP support
