Segmentation of petrographical images of marbles

Segmentation of Petrographical Images of Marbles

Microscope images of marble thin sections can be used to determine their geographical origin by means of the shapes, sizes, and spatial distribution of their grains. In this paper, we present a method that is the first step towards an automatic origin determination, namely, the segmentation of grains in digital images of thin marble sections. Each grain has a preferred direction, different from...

Performance Analysis of Segmentation of Hyperspectral Images Based on Color Image Segmentation

Image segmentation is a fundamental approach in the field of image processing and based on user’s application .This paper propose an original and simple segmentation strategy based on the EM approach that resolves many informatics problems about hyperspectral images which are observed by airborne sensors. In a first step, to simplify the input color textured image into a color image without tex...

Evaluation of methods of co-segmentation on PET/CT images of lung tumor: simulation study

Introduction: Lung cancer is one of the most common causes of cancer-related deaths worldwide. Nowadays PET/CT plays an essential role in radiotherapy planning specially for lung tumors as it provides anatomical and functional information simultaneously that is effective in accurate tumor delineation. The optimal segmentation method has not been introduced yet, however several ...
