the problem of curve detection decomposes naturally into two stages: (i) inferring the (discrete) trace and tangent to the curve;and (ii) finding integrals through the resultant tangent field. Orientation selection is...

In this paper, we propose a fuzzy relaxation technique that exploits fuzzy membership functions for gray level transformation. this technique enhances image contrast very effectively and expeditiously;different order ...

the problem of extracting the best data from poor quality line originals at the lowest possible resolution is considered. the form of the grey level histogram from such originals is examined, especially the shape of t...

this paper considers the application of the method of regularisation within the context of the restoration of degraded two-dimensional images. In particular, several recipes for choosing an appropriate degree of regul...

We report an attempt to derive simple low level features which may readily be extracted from an image. the features may be used to provide a classification of objects, so acting as a cue to aid further recognition. It...

this paper addresses the problem of performing global transforms of images on an SIMD machine proposed for imageprocessing [4]. In particular, parallel computation of two-dimensional fast Fourier transform (2-D FFT) ...

the development of an imageprocessing scheme for the analysis of cleavage cracks in minerals is described. the scheme is designed for use on digitised rock thin section micrographs. the cracks in a crystal image are ...
详细信息
the paper describes an integrated image segmentation/image analysis system. A segmentation algorithm which operates by tuning it's output to a pre-defined mathematical optimum is firstly outlined. Implementation o...
详细信息
the main result of this paper is that a projection of the classical Hough transform for line detection onto a subspace of the parameter space (accumulator) will yield a useless trivial result if the composite operator...
详细信息
In the coding of digital facsimile documents, a number of non-information-preserving codes have been proposed which make use of the repetition of binary patterns corresponding to printed or typewritten text characters...
