目前用于SAR图像溢油分割的主要是传统的图像分割方法，比如阈值分割。但由于SAR图像包含大量噪声，分割效果不佳，特别是海洋溢油区域包含大量的细长条油膜带，传统分割方法分割往往不能有效分割。本课题将Cooperative Model用于SAR图像细长条油膜带检测中，Cooperative Model是基于能量函数最小化的图像分割方法，能量函数的数据项采用有限伽马混合模型建模，并用EM（期望最大化）算法估计它的参数；能量函数的平滑项用高阶协作模型构建，它不仅惩罚边界长度，也考虑了物体边界的

In this paper, an ultrathin metalens has been proposed based on a holographic metasurface that consists of elongated apertures in 40 nm gold film, which exhibit intriguing properties such as on- and off-axis focusing and also can concentrate light in

We design and demonstrate new types of optical tweezers with lateral pulling forces that allow full control of biological samples with complex geometric shapes. With appropriate beam shaping, the dual tug-of-war tweezers effectively hold and stretch
