Methods from the theory of surfaces in differential geometry are applied to the gray tone
intensity and absorbance surfaces defined by a digital image. In particular, the first …

Introduces adaptive scale filtering, a general method for deriving shape from texture under
perspective projection without recourse to prior segmentation of the image into geometric …

We introduce a class of nonlinear differential equations that are solved using morphological
operations. The erosion and dilation act as morphological propagators propagating the …

An algorithm is presented for the characterization of the corner points in an image by means
of three parameters of easily understandable physical meaning, namely the amplitude …

This chapter reviews and discusses various aspects of texture analysis. The concentration is
on the various methods of extracting textural features from images. The geometric, random …

Publisher Summary This chapter discusses the problem of detecting edges in cellular
textures. Detecting edges is an important first step in the solution of many image analysis …

TEXTURAL PROPERTIES AS STATISTICS OF LOCAL PROPERTIES The usual definitions
of visual texture suggest that a texture is composed of large numbers of similar “basic …

Presents a non-feature-based solution to the problem of computing the shape of curved
surfaces from texture information. First, the use of local spatial-frequency spectra and their …

The aim of this work is a study and a comparison of certain global shape measures: squared
perimeter/area, mean vector radius divided by its standard deviation, bending energy of the …

An algorithm for the detection of edges between regions that differ in average gray level is
applied to the detection of other types of''texture edges,''involving abrupt changes in …
