To investigate the uniformity of copper particles in formulation design of copper-coated graphite, a quadrat-based method was presented with the image processing. Firstly, the particles were located by the foreground and background clustering algorithm. Then, an improved uniformity quantification model was established using the size and position of the particles. The findings based on the exper...

Size uniformity is one of the main criteria of superpixel methods. But size uniformity rarely conforms to the varying content of an image. The chosen size of the superpixels therefore represents a compromise how to obtain the fewest superpixels without losing too much important detail. We propose that a more appropriate criterion for creating image segments is information uniformity. We introdu...

background: brain tissue segmentation for delineation of 3d anatomical structures from magnetic resonance (mr) images can be used for neuro-degenerative disorders, characterizing morphological differences between subjects based on volumetric analysis of gray matter (gm), white matter (wm) and cerebrospinal fluid (csf), but only if the obtained segmentation results are correct. due to image arti...

The segmentation in medical images especially in the field of MR image is a challenging task in the presence of intensity inhomogenity. So many techniques have been devised to correct this artifact. The intensity inhomogenity also known as intensity non uniformity refers to the slow, non atomic intensity variations of the same tissue over the image domain. This paper attempts to review some of ...
