Description
Summary:Observation by means of the polarised light microscope plays a fundamental role in recognising typical patterns and detecting defects in the liquid crystal cells. The digital image processing greatly improves the experimental work allowing both quantitative and qualitative analysis. On the other hand, the high computation time required by image investigation methods restricts their application. We present a parallel version of an algorithm for pattern analysis and its fulfilment on a hypercube architecture, that reduces the computation time linearly with the number of used processors.
