چکیده
Abstract The aim of this work is to develop an automated procedure based on machine learning capabilities for the identification pearlite islands within two-phase pearlitic–ferritic steel. input parameters custom implementation a braided neural network are provided as data set scanning electron microscopy images metallographic specimens. procedures related processing and optimization affecting final architecture effectiveness stage examined. objective find best solution problem ferritic–pearlitic microstructure segmentation, allowing further during, e.g., 3D reconstruction from serial sectioning. examines various quality different U-Net architectures one that can identify with highest precision. Two types acquired secondary (SE) backscattered diffraction (EBSD) detectors used during investigation. revealed developed approach offers improvements in investigations by removing requirement expert knowledge interpretation image prior characterization. It has also been proven artificial networks deep process using extensible nonlinear tools microstructure, while overtraining level remains low. Convolutional do not require manual feature extraction able automatically appropriate search functions recognize structure areas training without human intervention. was shown recognizes analyzed steel satisfactory precision 79% EBSD 87% SE images.

Recurrent Residual Convolutional Neural Network based on U-Net (R2U-Net) for Medical Image Segmentation
Deep learning (DL) based semantic segmentation methods have been providing state-of-the-art performance in the last few years. More specifically, these techniques have been successfully applied to medical image classification, segmentation, and detection tasks. One deep learning technique, U-Net, has become one of the most popular for these applications. In this paper, we propose a Recurrent Co...
متن کاملU-Net: Convolutional Networks for Biomedical Image Segmentation
There is large consent that successful training of deep networks requires many thousand annotated training samples. In this paper, we present a network and training strategy that relies on the strong use of data augmentation to use the available annotated samples more efficiently. The architecture consists of a contracting path to capture context and a symmetric expanding path that enables prec...
متن کاملAutomatic segmentation of glioma tumors from BraTS 2018 challenge dataset using a 2D U-Net network
Background: Glioma is the most common primary brain tumor, and early detection of tumors is important in the treatment planning for the patient. The precise segmentation of the tumor and intratumoral areas on the MRI by a radiologist is the first step in the diagnosis, which, in addition to the consuming time, can also receive different diagnoses from different physicians. The aim of this study...
