    摘要: Etched wafers and methods of forming the same are disclosed. In one embodiment, a method of etching a wafer is provided. The method includes forming a metal hard mask on the wafer using electroless plating, patterning the metal hard mask, and etching a plurality of features on the wafer using an etcher. The plurality of featured are defined by the metal hard mask.

    摘要: Feature processing is provided for lung nodules in computer-assisted diagnosis. A feature that may better distinguish nodules from background is extracted using a Hough transform. Rather than relying on a specific boundary shape, the Hough transform accumulates evidence associated with a region, such as a ring region. The accumulated evidence provides a feature score without requiring a nodule to fit a specific shape. In another approach, a background level is determined from extracted features. Rather than attempting to normalize an image prior to extraction, the features are normalized. The feature normalization and generalized Hough transform extraction may be used together or alone.
