scikit-image

scikit-image is a collection of algorithms for image processing. It is available free of charge and free of restriction. We pride ourselves on high-quality, peer-reviewed code, written by an active community of volunteers. scikit-image provides a versatile set of image processing routines in Python. This library is developed by its community, and contributions are most welcome! scikit-image aims to be the reference library for scientific image analysis in Python. We accomplish this by being easy to use and install. We are careful in taking on new dependencies, and sometimes cull existing ones, or make them optional. All functions in our API have thorough docstrings clarifying expected inputs and outputs. Conceptually identical arguments have the same name and position in a function signature. Test coverage is close to 100% and code is reviewed by at least two core developers before being included in the library.

Libpixel

The only image processing solution that is dead simple and saves you hundreds of hours of engineering time. We process your images on the fly as you request them. You only need the originals. In order to request images of the correct width, height or processed in other ways, you simply add the relevant parameters to the URL. For example, to stretch to fill a 200 x 200 pixel box, you would use a URL. We understand that some entities have unique circumstances, usually due to regulatory restrictions, and cannot rely on publicly hosted image processing services. We provide only image processing and delivery, so if you’re looking for cloud storage and sharing files, we’re probably not the right choice. To crop an image, you specify four parameters – the origin x and y (which defines the top left of the crop rectangle) and the dimensions w and h (which define the size of the rectangle).
