Nonlinear adaptive processing of block coded images

Implementation and measurement: A 32 x 32 array is fabricated using a 0 . 8 ~ SPDM CMOS process. Each pixel occupies 88 x 9 2 p * with a fill factor of -25% as shown in Fig. 3. The dimensions of the whole chip are 4196 x 4196pmz. During the experiment, a patterned laser light spot is incident upon the chip. The output current of each pixel is accessed sequentially using two shift registers for ...

A nonlinear laplace operator as edge detector in noisy images

An edge detection scheme is developed robust enough to perform well over a wide range of signal-to-noise ratios. It is based upon the detection of zero crossings in the output image of a nonlinear Laplace filter. Specific characterizations of the nonlinear Laplacian are its adaptive orientation to the direction of the gradient and its inherent masks which permit the develop ment of approximatel...

Optimum Nonlinear

| This paper is composed of two parts. The rst part surveys the literature regarding optimum nonlinear l-tering from the (continuous-time) stochastic analysis point of view, and the other part explores the impact of recent applications of neural networks (in a discrete-time context) to nonlinear ltering. In particular, the results obtained by using a regularized form of radial basis function (R...

Learning Nonlinear Visual Processing from Natural Images

The paradigm of computational vision hypothesizes that any visual function – such as the recognition of your grandparent – can be replicated by computational processing of the visual input. What are these computations that the brain performs? What should or could they be? Working on the latter question, this dissertation takes the statistical approach, where the suitable computations are attemp...

Determination of the optimum sampling frequency of noisy images by spatial statistics.

In optical metrology the final experimental result is normally an image acquired with a CCD camera. Owing to the sampling at the image, an interpolation is usually required. For determining the error in the measured parameters with that image, knowledge of the uncertainty at the interpolation is essential. We analyze how kriging, an estimator used in spatial statistics, can generate convolution...
