Abstract

OBJECTIVES

In this paper, we look at how to design and build a system to find tumors using 2 Convolutional Neural Network (CNN) models. With the help of digital image processing and deep Learning, we can make a system that automatically diagnoses and finds different diseases and abnormalities. The tumor detection system may include image enhancement, segmentation, data enhancement, feature extraction, and classification. These options are set up so that the CNN model can give the best results.

METHODS

During the training phase, the learning rate is used to change the weights and bias. The learning rate also changes the weights. One Epoch is when all of the training images are shown to the model. As the training data may be very large, the data in each epoch are split into batches. Every epoch has a training session and a test session. After each epoch, the weights are changed based on how fast the CNN is learning. This is done with the help of optimization algorithms. The suggested technique uses the anticipated mean intersection over union value to identify failure instances in addition to forecasting the mean intersection over union.

RESULTS

This paper talks about how to separate brain tumors from magnetic resonance images of patients taken from "Brain web." Using basic ideas of digital image processing, magnetic resonance images are used to extract and find tumors using a hybrid method. In this paper, the proposed algorithm is applied with the help of MATLAB. In medical image processing, brain tumor segmentation is an important task. The goal of this paper is to look at different ways to divide brain tumors using magnetic resonance imaging. Recently, automatic segmentation using deep learning methods has become popular because these methods get the best results and are better at solving this problem than others. Deep learning methods can also be used to process and evaluate large amounts of magnetic resonance imaging image data quickly and objectively.

CONCLUSIONS

A classification method based on a convolution neural network is also added to the proposed scheme to make it more accurate and cut down on the amount of time it takes to do the calculations. Also, the results of the classification are given as images of a tumor or a healthy brain. The training is 98.5% correct. In the same way, both the validation accuracy and validation loss are high.

摘要

目的

本文探讨了如何设计和构建一个使用 2 个卷积神经网络(CNN)模型来发现肿瘤的系统。借助数字图像处理和深度学习,我们可以构建一个能够自动诊断和发现不同疾病和异常的系统。肿瘤检测系统可能包括图像增强、分割、数据增强、特征提取和分类。这些选项的设置是为了使 CNN 模型能够得出最佳结果。

方法

在训练阶段,学习率用于改变权重和偏差。学习率也会改变权重。一个 Epoch 是指所有训练图像都呈现给模型的时间。由于训练数据可能非常大,因此将数据在每个 Epoch 中划分为批处理。每个 Epoch 都有一个训练会话和一个测试会话。在每个 Epoch 之后,根据 CNN 的学习速度来改变权重。这是通过优化算法来实现的。所提出的技术除了预测平均交并比之外,还使用预期的平均交并比来识别故障实例。

结果

本文讨论了如何从“Brain web”中获取的患者磁共振图像中分离出脑肿瘤。使用数字图像处理的基本思想,通过混合方法提取和发现磁共振图像中的肿瘤。在本文中,借助 MATLAB 应用了所提出的算法。在医学图像处理中,脑肿瘤分割是一项重要任务。本文的目的是研究使用磁共振成像分割脑肿瘤的不同方法。最近,基于深度学习方法的自动分割变得流行起来,因为这些方法可以得到最佳结果,并且比其他方法更擅长解决这个问题。深度学习方法还可以快速、客观地处理和评估大量磁共振成像图像数据。

结论

还向提出的方案中添加了基于卷积神经网络的分类方法,以提高其准确性并减少计算时间。此外,分类结果以肿瘤或健康大脑的图像形式给出。训练的准确率为 98.5%。同样,验证精度和验证损失也很高。
