Modified Laser Speckle Imaging with Adaptive Window
摘要
Abstract
One of the advantages of laser speckle is detecting micro-vascular through image processing. This paper proposes a new image processing method for laser speckle, adaptive window method that adaptively processes laser speckle images in the space. Disadvantage of conventional fixed window method is that it uses the same window size regardless of target areas. Inherently laser speckle contains undesired noise. Thus a large window is helpful for removing the noise, but it results in low resolution of image. Otherwise a small window may detect micro vascular but it has limits in noise removal. To overcome this trade-off, the concept of adaptive window method is newly introduced to conventional laser speckle image analysis. In addition, the modified adaptive window method applied to other selection images. We have compared conventional Laser Speckle Contrast Analysis(LASCA) and its variants with the proposed method in terms of image quality and processing complexity. Moreover compared the result of the accompanied changing selection images have also been compared.关键词
