Ciresan et al. [121] designed a CNN segmentation algorithm for brain images where a postprocessing step removed artifacts that were smaller than a predefined threshold; the CNN kernel sizes were chosen to reduce overfitting to a small training set size. Although there are many computer vision techniques for image segmentation, some have been adapted specifically for medical image computing. Because segmentation partitions the image into coherent regions, clustering procedures can be applied for segmentation by extracting the global characteristics of the image to professionally separate the ROI from the background. Recently, convolutional neural networks (CNNs) have achieved tremendous success in this task, however, it performs poorly at recognizing precise object boundary due to the information loss in the successive downsampling layers. Convenient methods should be developed. The classification process has been carried out using SVM with different kernel functions and optimization procedures. Medical Image Segmentation is the process of identifying organs or lesions from CT scans or MRI images and can deliver essential information about the shapes and volumes of these organs. Fuzzy clustering has been used with optimization of three objective functions, namely, symmetry distance-based cluster validity index, global fuzzy clusters compactness, and fuzzy separation. Moreover, due to the irregular and fuzzy borders in most of the medical images, fuzzy set and neutrosophic set theories become important in the segmentation process to handle uncertainty in the medical images. Uncertainty, which can be considered as noise in image processing, is challenging in medical image segmentation. The basic structure of a U-net architecture … Our techniques show new insights by using methods such as histogram decomposition in conjunction with new techniques, such as fusion. Normalized cuts and image segmentation. Section 2 reports several related studies to the neutrosophic set, neutrosophic c-means, clustering-based unsupervised segmentation, graph cut, and the kernel graph cut in medical image segmentation and specifically for skin lesion segmentation. The semisupervised approach is applicable in domains such as image segmentation, where users may have a small set of manually derived labeled data, and can use it to supervise classification of the remaining pixels in a single image. The optimal solution has been determined using the metaclustering procedure. EJNMMI Res. When ni = Xtr, i, the ni need not be equal, nor is it necessary that the columns of Utr be crisp. Many techniques and methods have been i mprovised to developed to such challenges. Techniques of this kind in the context of c-means clustering were first discussed by Pedrycz [44]. Medical image classification is an important research arena in the developing attention of the research community and the medical industry [6]. Roughly speaking, semisupervision exchanges the generalization capability of a classifier trained with (Xtr, Utr) for access to the structural information possessed by the points in both Xtr and Xte while searching for clusters Ute of Xte. Image segmentation is vital to medical image analysis and clinical diagnosis. In a followup work, Xu et al. Consequently, this chapter proposes a hybrid skin lesion segmentation system combining NS-based clustering and kernel graph cut segmentation using the NCM and KGC methods to realize an efficient and unsupervised skin lesion segmentation solution. The fuzzy membership functions can be considered to construct truth, falsity, and indeterminacy memberships. In this application, crisply labeled training pixels are chosen by a set of rules that identify tissue types with a high degree of confidence. Would you like email updates of new search results? R.

Accordingly, the fuzzy c-means algorithm (FCM) (Kang, Min, Luan, Li, & Liu, 2009) and neutrosophic c-means (NCM) clustering can be applied to improve different segmentation techniques. Multiple FCNs were cascaded in a hierarchical structure such that the early-stage FCNs learnt the coarse appearance and localization information while the late-stage FCNs learnt the subtle characteristics of the ROI boundaries. The expectation–maximization algorithm is utilized to iteratively estimate the a posterior probabilities and distributions of labeling when no training data is available and no estimate of segmentation model can be formed. In satellite imagery, image segmentation can be used to detect roads, bridges while in medical imaging analysis, it can be used to detect cancer. [40] proposed an algorithm for segmenting the liver portal veins from an arterial stage. Deformable models for medical image segmentation are often enhanced by their use of prior shape information. Various segmentation approaches can be used, including those based on boundaries such as the deformable model, while other approaches are region-based methods such as region merging, region growing, and active contour (Al-azawi, Abdulhameed, & Ahmed, 2017; Baldevbhai & Anand, 2012; Sharma & Aggarwal, 2010). Corresponding multimodal image analysis and ensemble learning schemes have seen rapid growth and bring unique value to medical applications.
