A parallel algorithm of texture analysis for liquid crystal investigation

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