Increasing sensitivity of a multispectral MR image analysis based on pseudocoherent holographic interferometry imaging method

摘要

A new method of low contrast multispectral image sensitive analysis is outlined. The method is based on consideration of an analyzed image as a virtual rough surface. The one is illuminated with virtual pseudocoherent optical wave. Interaction of a reflected wave with a reference one gives possibility for synthesis of a new interferometric complex image. Analysis of a new image allows to detect very small brightness variations which are invisible for direct visual observations. Information possibilities of the new method are compare with known methods of histogram equalization and fuzzy C-means clustering. Experimental results are shown that new method provides a significant increasing in sensitivity and space resolving power of low contrast image analysis in compare with known methods.
