This document describes a study that used deep semantic networks to segment nucleus and cytoplasm from Pap smear images. The researchers used neural network architectures like ResNet and FC-Densenet for semantic segmentation. They preprocessed the Pap smear images, which were assigned different colors for nucleus, cytoplasm and background. The images were padded to a uniform size of 128x128 pixels. Data augmentation was also performed by flipping images. The neural networks were then trained on this dataset to perform pixel-wise segmentation of nucleus and cytoplasm, with the goal of improving automated Pap smear analysis.
3D Segmentation of Brain Tumor ImagingIJAEMSJORNAL
A brain tumor is a collection of anomalous cells that grow in or around the brain. Brain tumors affect the humans badly, it can disrupt proper brain function and be life-threatening. In this project, we have proposed a system to detect, segment, and classify the tumors present in the brain. Once the brain tumor is identified at the very beginning, proper treatments can be done and it may be cured.
The document discusses using a U-Net convolutional neural network to automatically segment brain tumors in MRI images. It aims to eliminate the need for domain expertise by using deep learning to extract hierarchical features. The U-Net model is trained on the BRATS 2017 dataset and is able to segment tumors with 5% higher accuracy than previous methods, as measured by the Dice similarity coefficient. The system could be expanded to analyze additional MRI modalities and further improve automated tumor detection.
A New Algorithm for Fully Automatic Brain Tumor Segmentation with 3-D Convolu...Christopher Mehdi Elamri
This document describes a new algorithm for fully automatic brain tumor segmentation using 3D convolutional neural networks. The algorithm uses 3D convolutional filters to preserve spatial information, and a high-bias CNN architecture to increase effective data size and reduce model variance. On a dataset of 274 brain MR images, the algorithm achieved a median Dice score of 89% for whole tumor segmentation, significantly outperforming past methods. This demonstrates the effectiveness of generalizing low-bias high-variance methods like CNNs to learn from medium-sized datasets.

Brain Image Fusion using DWT and Laplacian Pyramid Approach and Tumor Detecti...INFOGAIN PUBLICATION
Image fusion is the process of combining important information from two or more images into a single image. The resulting image will be more enhanced than any of the input pictures. The idea of combining multiple image modalities to furnish a single, more enhanced image is well established, special fusion methods have been proposed in literature. This paper is based on image fusion using laplacian pyramid and Discreet Wavelet Transform (DWT) methods. This system uses an easy and effective algorithm for multi-focus image fusion which uses fusion rules to create fused image. Subsequently, the fused image is obtained by applying inverse discreet wavelet transform. After fused image is obtained, watershed segmentation algorithm is applied to detect the tumor part in fused image.

BRAIN TUMOR MRI IMAGE SEGMENTATION AND DETECTION IN IMAGE PROCESSINGDharshika Shreeganesh
Image processing is an active research area in which medical image processing is a highly challenging field. Medical imaging
techniques are used to image the inner portions of the human body for medical diagnosis. Brain tumor is a serious life altering
disease condition. Image segmentation plays a significant role in image processing as it helps in the extraction of suspicious regions
from the medical images. In this paper we have proposed segmentation of brain MRI image using K-means clustering algorithm

ELM-LRF has advantages over other methods like reduced training time, fast results, no getting stuck in local minima, and finding the best weights in one iteration due to local connections between input and output. The research concludes that ELM-LRF is well-suited for face recognition systems.
Comparitive study of brain tumor detection using morphological operatorseSAT Journals
Abstract
Segmentation divides an image into foreground object and the background object. In our case foreground object is brain tumor and background is CSF, white matter, and grey matter. Aim of our study is to detect the tumor and remove the background completely and compare the morphological operations that can be used for this purpose. Segmentation remains a challenging area for researchers since many segmentation methods results in over segmentation or under segmentation and hence, leads to the false interpretation of the results. The proposed work is the comparative study of the morphological segmentation methods for segmenting brain tumor from MRI images. Before segmentation, filtration process is carried out using two method, Non Local mean filter and median filter and their results are compared using MSE and PSNR. NL mean filter preserves sharp edges and fine details in an image hence, preferred over median filter. Also tumor location is identified, to get an approximate idea about the position of the tumor in the brain i.e. in which part the brain tumor is located. The tumor is identified by using different algorithms which are based on morphology such as watershed segmentation, morphological erosion, and hole filling algorithm and comparison between them is carried out based on parameters like accuracy, sensitivity and elapsed time. Each of the segmentation results are compared with the tumor obtained using interactive tool present in MATLAB R2013b.

A Survey on Segmentation Techniques Used For Brain Tumor DetectionEditor IJMTER
In recent years Brain tumor is one of the most commonly found causes for death among
children and adults. Early detection of tumor is a must in order to reduce the death rate. For tumor
detection various image techniques can be used. In this paper we mainly concentrate on the images
obtained from MRI scans. In MRI images, the tumor may appear clearly, but for further treatment
the physician need to be a qualified and well experienced person. In order to help the radiologist in
detection computer-aided diagnosis was developed. The generation of a CAD system consists of
several processes and among them segmentation is considered to the most important process. Image
Segmentation is a process of partitioning an image into multiple segments. The main objective of
segmentation is to represent the image into a simplified form so as to increase the efficiency and
accuracy of the system. Therefore the segmentation of brain tumor can be considered as an important
role in the medical image process. Hence in this paper we concentrate on the recently used
segmentation techniques for the detection of tumor using MRI images.

New foreground markers for Drosophila cell segmentation using marker-controll...IJECEIAES
Image segmentation consists of partitioning the image into different objects of interest. For a biological image, the segmentation step is important to understand the biological process. However, it is a challenging task due to the presence of different dimensions for cells, intensity inhomogeneity, and clustered cells. The marker-controlled watershed (MCW) is proposed for segmentation, outperforming the classical watershed. Besides, the choice of markers for this algorithm is important and impacts the results. For this work, two foreground markers are proposed: kernels, constructed with the software Fiji and Obj.MPP markers, constructed with the framework Obj.MPP. The new proposed algorithms are compared to the basic MCW. Furthermore, we prove that Obj.MPP markers are better than kernels. Indeed, the Obj.MPP framework takes into account cell properties such as shape, radiometry, and local contrast. Segmentation results, using new markers and illustrated on real Drosophila dataset, confirm the good performance quality in terms of quantitative and qualitative evaluation.

Finally, the probabilistic neural network classifier determines if the tumor is benign or malignant based on the fused image features.
