Nonlinear optical Fourier filtering technique for medical image processing.

Real-time nonlinear optical Fourier filtering for medical image processing is demonstrated, exploiting light modulating characteristics of thin films of the biophotonic material bacteriorhodopsin (bR). The nonlinear transmission of bR films for a 442 nm probe beam with a 568 nm control beam and vice versa is experimentally studied in detail. The spatial frequency information carried by the blue...

Some Analog Linear Filtering Tasks Useful in Medical Image Processing

In this paper some analog linear filtering tasks and their possible applications in medical image processing are approached. Although the presented processing tasks can be also implemented digitally, we treated their realization using cellular neural networks (CNNs). We discuss here the implementation of a 2-D FIR Gaussian filter and a class of IIR maximally-flat low-pass filters. Finally, simu...

Adaptive Nonlinear Filtering for Nonlinear Anisotropic Diffusion Approximation in Image Processing

Multi-scale image enhancement and representation is an important part of biological and machine early vision systems. The process of constructing this representation must be both rapid and insensitive to noise, while retaining image structure at all scales. This is a complex task as small scale structure is difficult to distinguish from noise, while larger scale structure requires more computat...

Nonlinear filtering for phase image denoising - Vision, Image and Signal Processing, IEE Proceedings-

The problem of phase image denoising through nonlinear (NL) filtering is addressed. There are various imaging systems in which the phase information is utilised to generate useful imaging data. However, the presence of noise makes difficult to obtain the appropriate phase image. The authors apply NL vector filtering techniques to denoise the complex data from which the phase image is extracted....

Nonlinear Filtering for Image Analysis and Enhancement

Digital image enhancement and analysis have played, and will continue to play, an important role in scientific, industrial, and military applications. In addition to these applications, image enhancement and analysis are increasingly being used in consumer electronics. Internet Web users, for instance, rely on built-in image processing protocols such as JPEG and interpolation and in the process...
