Normalized Scale-Space Derivatives: A Statistical Analysis
نویسنده
چکیده
This chapter presents a statistical analysis of multiscale derivative measurements. Noisy images and multiscale derivative measurements made of noisy images are analyzed; the means and variances of the measured noisy derivatives are calculated in terms of the parameters of the probability distribution function of the initial noise function and the scale or sampling aperture. Normalized and unnormalized forms of differential scale space are analyzed, and the statistical results are compared. A discussion of the results and their ramifications for multiscale analysis is included.

Recognizing Golddsh? or Local Scale Selection for Recognition Techniques
This paper addresses the problem of the local scale parameter selection for recognition techniques based on Gaussian derivatives. Patterns are represented in a local subspace or feature space of which each dimension is a scale normalized receptive eld (a unit composed of normalized Gaussian derivativessLin98]). Data are structurally represented in a feature space for the recognition of static d...
متن کاملDense scale selection over space, time and space-time
Scale selection methods based on local extrema over scale of scale-normalized derivatives have been primarily developed to be applied sparsely — at image points where the magnitude of a scale-normalized differential expression additionally assumes local extrema over the domain where the data are defined. This paper presents a methodology for performing dense scale selection, so that hypotheses ...
متن کاملThe Hausdor Dimension and Scale - SpaceNormalisation of Natural
Fractal Brownian motions have been introduced as a statistical description of natural images. We analyze the Gaussian scale-space scaling of derivatives of fractal images. On the basis of this analysis we propose a method for estimation of the fractal dimension of images and scale-space normalisation used in conjunction with automatic scale selection assuming either constant energy over scale o...

متن کاملScale-Space
Scale-space theory is a framework for multiscale image representation, which has been developed by the computer vision community with complementary motivations from physics and biologic vision. The idea is to handle the multiscale nature of real-world objects, which implies that objects may be perceived in different ways depending on the scale of observation. If one aims to develop automatic al...
