    An optical holographic analogue of Hopfield's neural network model is also presented. Using Fourier transform holograms, limited shift invariant associative memories have been fabricated. A pattern recognition scheme is modified and is implemented optically using a simple and different way of achieving thresholding in the correlation domain. inherent pattern recognition ability in language understanding, and also; problem solving ability using pattern discovery. Give it a serious try and then proceed with the solution. Solution: Pattern: Instead of random scrambling, the letters between the first and the last were just inverted - a simple action resulting in powerful effect.

    Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo (for example the text on signs and billboards in a landscape photo) or from subtitle text superimposed on an image (for example from a.   Hsu YN, Arsenault HH () Optical pattern recognition using circular harmonic expansion.

By Neil Collings, Addison- Wesley Publishing Company, pp. ISBN Price: £17   Optical Holography deals with the use of optical holography to solve technical problems, with emphasis on the properties of holograms formed with visible light.

Topics covered include the Fourier transform, propagation and diffraction, pulsed-laser holography, and optical Book Edition: 1. An optical-digital system for the pattern recognition of coal-workers' pneumoconiosis is described. The system consists of a coherent-optical configuration to generate the Fourier irradiance of the radiographic image and a digital computer to process the data.

The first chapter is devoted to pattern recognition performed with optical correlators. Later chapters discuss new approaches based on neural networks, wavelet transforms, and the fractional Fourier transform. The book also covers nonlinear filter methods and optical-electronic hybrid systems.5/5(1).

Abstract A unified treatment of the theories, techniques, and applications of automated identification devices used for the holographic pattern recognition is presented.

Topics include the optical processing of information during pattern recognition, the basic theories of holographic identification of images, methods of holographic filtration.

The holographic fringe pattern of a 3D object is obtained using an in-line interferometry setup. The Fourier matched filters are applied to the complex image reconstructed from.Holography, on the other hand does not utilize a lens to form a latent image.

It relies on the principle of interference to produce an image. The interference pattern is captured by the film and processed.

The hologram is then illuminated with laser light (transmission) or white light (reflection). A holographic image is then Size: KB.
