Abstract: The proposed image-processing method for determining the structural strength of a test object with a diffuse-scattering surface involves: the creation of an interferogram based on radiation back-scattered by the surface of the test object; conversion of the interferogram into a modulo-2.pi. image; and the stabilisation of the modulo-2.pi. image to form an output grey scale value image. From the latter, an identical duplicate grey scale value image is produced; this is then geometrically shifted and modified by applying an invariable grey scale value in the entire image area, before being finally subtracted from the initial grey scale value image to produce a grey scale image containing easily evaluated information on deformities in the observed test object.

Abstract: A speech recogniser in which the recognition vocabulary is generated from a user's own speech by forming phonemic transcriptions of the user's utterances and using these transcriptions for future recognition purposes. The phonemic transcriptions are generated using a loosely constrained network, preferably one constrained only by noise. The resulting transcriptions therefore bear close resemblance to the user's input speech but require significantly reduced storage requirements compared to known speaker dependent word representations.
