Digital Image Analysis for the Determination of Size and Shape .

Digital Image Processing gives more reliable results because it not only generates the dimensional size of the grains, as in case of mechanical sieving, but also the shape parameters of soil grains oriented on its largest base area. Thus it can be used for more accurate determination of the size distribution of sand grains.

Use of digital image analysis combined with fractal theory to .

Along this line, analysis of the influence of geometrical aspects of soil grains is usually restricted to the particle size distribution measured by sieve tests. However, the accuracy of sieving will be better for spherically shaped grains and the test cannot determine the textural parameters, such as shape and roughness.

An Algorithm for the Pore Size Determination Using Digital Image .

Abstract. The study is concerned with putting forth a novel method of determination the pore size and its distribution for pores of different shapes. The identification of irregular and branched pores is associated with difficulties in their separation, as well as in the quantification of their size and shape characteristics. Recent.
