Image segmentation

Segmentation refers to the process of partitioning a digital image into multiple segments, also known as superpixels. The goal of segmentation is to simplify and/or change the representation of an image into something that is more meaningful and easier to analyse.

Image segmentation is typically used to locate objects and boundaries (e.g. lines, curves) in images. More precisely, the term ‘image segmentation’ refers to the process of assigning a label to every pixel in an image such that pixels with the same label share certain visual characteristics.

The result of image segmentation is a set of segments that collectively cover the entire image, or a set of contours extracted from the image. Each of the pixels in a region is similar with respect to some characteristic or computed property, such as colour, intensity or texture. Adjacent regions are significantly different with respect to the same characteristics.

tool: Zoomify

A suite of products developed for web designers that may be used to convert large images into a form that can be zoomed and panned. Zoomify enables large images to be viewed and manipulated, without an increase in server load or download time. It convert large images stored in raster formats (e.g. TIFF, JPEG) into a set of pieces or 'tiles' The individual pieces contain sub-sections of the image at different resolutions or levels of zoom, which are combined to create a type of mosaic.
