Information Electronics Department, Ewha Womans University, Seoul 120 750, Korea
IEEE Trans Med Imaging 23:1430-44. 2004..We have investigated the properties of the proposed method by theoretical analysis, computer simulations, a phantom experiment, and with functional magnetic resonance imaging data...
- Retrospective correction of nonuniform illumination on bi-level imagesHana Lee
Department of Electronics Engineering, Ewha Womans University, 11 1 Daehyun Dong, Seodaemun gu, Seoul, Korea
Opt Express 17:23880-93. 2009..In addition, it yields a unique solution since the minimization of the objective function is well-posed. In simulations and experiments, the method showed better accuracy and speed than the conventional entropy-based method...
