# Welcome to CompuMAINE

The Computational Modeling, Analysis of Imagery and Numerical Experiments (CompuMAINE) lab is an image and signal processing, analysis, and modeling laboratory located at the University of Maine flagship campus. It was founded by Dr. Andre Khalil. CompuMAINE applies mathematical methods, particularly wavelet-based characterization, to images to elucidate and quantify novel properties of scientific interest. CompuMAINE is a proud partner of the Maine Cancer Foundation.

Projects range from multifractal image analysis to wavelet-based segmentation and characterization of chromosome territories and mammograms to the study of the interstellar medium. Over the years, we have adapted and further developed our methodologies for 1D, 2D, and 3D data analysis, in particular to perform a fractal-based segmentation of microcalcification clusters from breast tissue backgrounds of varying densities and to accurately segment objects of interest from fluorescence microscopy images with noisy backgrounds.

Take a look at CompuMAINE’s research and get to know our lab members. Let us know if you’re interested in working with us.
