The CAS (concentration, asymmetry, smoothness) parameters are a tool originally developed in astronomy to characterize the shapes and images of objects with some central concentration. Each parameter is a single number which represents some aspect of the structure of the object under study. These parameters were originally developed by astronomers to quantify the light distribution of galaxies, as a way to avoid having to use visual estimates of galaxy morphological classification. They have also been used in biological imaging, and other areas of imaging analysis. Each parameter is measured in a well defined way and within a well defined radius.
