ImagePlot is a free software tool that visualizes collections of images and video of any size. It is implemented as a macro which works with the open source image processing program ImageJ.
Visualize image collections as timelines and scatter plots which display all images in a collection. Find images that are outliers. Discover clusters - sets of images that are similar in content or visual properties. Visualize multiple sets of images to better understand their similarities and differences. Explore patterns in existing metadata (i.e., dates, names, etc.), added annotations and keywords, or visual features (i.e., brightness, saturation, hue, shapes, etc.)
