LabelMe

What LabelMe is

LabelMe is a web-based image annotation tool for researchers labeling images and sharing annotations. It supports polygon, scribble, and mask annotation; polygon tools can create shapes, rename objects, change control points, or remove objects. URL options provide navigation through a folder or collection, random image selection, and a Mechanical Turk mode. A command-line script can create image collections from all images or a chosen folder. Annotations are saved as XML in an Annotations folder, with downloads available through a MATLAB toolbox or tar files. The toolbox can retrieve a dataset or access images and annotations online, though online access may be slow. The source is intended for installation on a web server and use through a browser, and Docker files are included. Setting it up requires Apache, server-side includes, and Perl/CGI support. The quick start specifies JPG images and alphanumeric folder and file names without spaces or unusual characters. The server also needs read access to images and write access to annotation, temporary annotation, and log locations.
