Xiaolei Huang directs the Image Data Emulation and Analysis Lab at Lehigh. Her research interests are in the areas of biomedical image analysis, computer vision, and computer graphics. Her focus is on studying deformable (non-rigid) object modeling, segmentation, registration, tracking and recognition problems. Dr. Huang's broader interests include rich-content data (image and graphics) structuring and querying, physically-based modeling and simulation, machine learning, visual cognition, bioinformatics, and artificial intelligence. Huang harnesses the power of the computer to process and interpret biomedical images. One of her software programs constructs 4-D computer models -- with time as the fourth dimension -- that measure the changes in the heart’s structure as it expands and contracts. The models help cardiologists discern the differences between the normal deformations that occur in healthy hearts and the abnormal deformations that occur in damaged and diseased hearts.
