Despeckle – remove positive and negative spots, smoothing edges; Binarisation – Convert an image from color or greyscale to black-and-white (called a "binary image" because there are two colors). This work shows that the following problems are equivalent, both in theory and in practice:. First, consider an image with a few air speckles (figure A below, note a few red speckles in the air). Therefore, despeckling is essential for subsequent feature extraction and classification. The resolution of the grid (i. All signal processing devices, both analog and digital, have traits that make them susceptible to noise. The availability of aberration corrected microscopes, operating in a scanning mode (STEM), as well as very thin substrates enables the imaging of very small particles with atomic resolution. I sharpen the picture, "despeckle" the image, add a guassian blur, and then find the edges of the image. To successfully vectorize the images in WinTopo, various image processing techniques such as erosion, despeckle, and prune were used to create an acceptable image that could be processed using edge detection. 如果停留在研究despeckle的算法层面且针对Intensity信息,那确实不需要使用原数据,因为despeckle寻找的是空间上的反射元domain,然后把噪点滤掉(spatial filter)而最原始的数据在没有转换和处理之前是没有空间关系的。.
