Segmentation of Ultrasound Images by Using an Incremental Self-organized Map
نویسندگان
چکیده
This paper presents a new segmentation method for ultrasound images. A new incremental self–organized map is proposed for the segmentation of the ultrasound images. Elements of the feature vectors are formed by the fast Fourier transform (FFT) of image intensities in 4×4 square blocks. In this study, two neural networks for segmentation are comparatively examined: Kohonen map, and incremental self– organized map (ISOM). It is observed that ISOM gives the best classification performance with less number of nodes after a short training time.

A Method for Body Fat Composition Analysis in Abdominal Magnetic Resonance Images Via Self-Organizing Map Neural Network
Introduction: The present study aimed to suggest an unsupervised method for the segmentation of visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) in axial magnetic resonance (MR) images of the abdomen. Materials and Methods: A self-organizing map (SOM) neural network was designed to segment the adipose tissue from other tissues in the MR images. The segmentation of SAT and VA...

This paper presents an improved incremental self-organizing map (I2SOM) network that uses automatic threshold (AT) value for the segmentation of ultrasound (US) images. In order to show the validity of proposed scheme, it has been compared with Kohonen’s SOM. Two-dimensional (2D) fast Fourier transform (FFT) and 2D continuous wavelet transform (CWT) were computed in order to form the feature ve...

Reducing the number of colors in an image while preserving its quality, is of importance in many applications such as image analysis and compression. It also decreases memory and transmission bandwidth requirements. Moreover, classification of image colors is applicable in image segmentation and object detection and separation, as well as producing pseudo-color images. In this paper, the Kohene...
متن کاملSegmentation of Multispectral MR Images Using a Hierarchical Self-Organizing Map
The application of a hierarchical self{organizing map (HSOM) to the problem of segmentation of multispectral magnetic resonance (MR) images is investigated. The HSOM is composed of several layers of the self{organizing map (SOM) organized in a pyramidal fashion. The SOM has been used for the segmentation of multispectral MR images but the results often su er from undersegmentation and oversegme...
متن کاملFully automated biomedical image segmentation by self-organized model adaptation
In this paper, we present a fully automated image segmentation method based on an algorithm that provides adaptive plasticity in function approximation problems: the deformable (feature) map (DM) algorithm. The DM approach reduces a class of similar function approximation problems to the explicit supervised one-shot training of a single data set. This is followed by a subsequent, appropriate si...
