Novel biphenyl-substituted 1,2,4-oxadiazole ferroelectric liquid crystals: synthesis and characterization.

Two novel series of unsymmetrically substituted 1,2,4-oxadiazole viz., R.Ox.

A modified shape context method for shape based object retrieval.

The complexity in shape context method and its simplification is addressed. A novel, but simple approach to design shape context method including Fourier Transform for the object recognition is described. Relevance of shape context, an important descriptor for the recognition process is detailed.
