基于levelset的测地活动轮廓 matlab源码，可实现多目标轮廓的 提取。对噪声图象具有良好的鲁棒性。但是计算量较大，耗时过多-levelset based on the geodesic active contour Matlab source, more achievable goal contour extraction. Image noise is a good robust. However, the large amount of calculation, time-cons

应用自适应过滤器实现信道均衡、消除回声和通过有源噪声控制衰减噪声-Adaptive filter to achieve channel equalization, echo and through the elimination of active noise control noise attenuation

ANC - project. This is a example on how to do it
