BREAST ULTRASOUND IMAGE SEGMENTATION BASED ON PARTICLE SWARM OPTIMIZATION AND THE CHARACTERISTICS OF BREAST TISSUE

GUO, YANHUI; CHENG, H. D.; ZHANG, YINGTAO - In: New Mathematics and Natural Computation (NMNC) 07 (2011) 01, pp. 135-154

Breast cancer occurs in over 8% of women during their lifetime, and is the leading cause of death among women. Sonography is superior to mammography because it has the ability to detect focal abnormalities in the dense breasts and has no side-effect. In this paper, we propose a novel automatic...

Adaptation of multifractal analysis to segmentation of microcalcifications in digital mammograms

Stojić, Tomislav; Reljin, Irini; Reljin, Branimir - In: Physica A: Statistical Mechanics and its Applications 367 (2006) C, pp. 494-508

A method for detecting microcalcifications in digital mammograms is proposed. After recognizing basic features of microcalcifications we introduced several modifications in multifractal analysis, obtaining an efficient method adapted to enhance only small light parts not belonging to surrounding...

Techniques for image enhancement and segmentation of tomographic images of porous materials

Sheppard, Adrian P.; Sok, Robert M.; Averdunk, Holger - In: Physica A: Statistical Mechanics and its Applications 339 (2004) 1, pp. 145-151

This article presents a three-stage approach, combining novel and traditional algorithms, for the segmentation of images of porous and composite materials obtained from X-ray tomography. The first stage is an anisotropic diffusion filter which removes noise while preserving significant features....
