Snake Segmentation and U-Net Classification for Enhanced Brain Tumor Detection

Problem Definition

After conducting a thorough literature review, it is evident that the current methods for detecting and identifying brain tumors using machine learning and deep learning models face several limitations and challenges. One key issue is the imbalance in brain imaging data, where tumors are small in proportion to the overall size of the brain, leading to biased segmentation results. This imbalance often results in classifiers being trained on data that is skewed towards a particular class, resulting in low true positive rates. Additionally, existing deep learning algorithms used for brain tumor segmentation are time-consuming due to their complex frameworks, making them less practical for real-time applications. The filters employed in traditional models for denoising images and reducing errors have also been found to be ineffective, further impacting the overall performance of these models.

Therefore, there is a critical need for a new and improved brain tumor segmentation model that can address these limitations and provide more accurate and efficient results for early detection and treatment of brain tumors.

Objective

The objective is to develop a new and improved brain tumor segmentation model that addresses the limitations of current methods by focusing on pre-processing, segmentation, and classification phases. The goal is to reduce Mean Square Error (MSE) and execution time of the detection model. By incorporating advanced techniques such as Snake segmentation, PNLM filter, and U-Net architecture, the proposed approach aims to enhance the accuracy and efficiency of tumor segmentation and classification for early detection and treatment of brain tumors.

Proposed Work

To address the limitations of current brain tumor detection models, a new approach is proposed in this paper focusing on pre-processing, segmentation, and classification phases. The main goal is to reduce Mean Square Error (MSE) and execution time of the detection model. Initially, MR images from the BRATS dataset are pre-processed using a Gaussian Filter to remove noise and retain important data. Subsequently, the images are segmented using the Snake segmentation technique to effectively isolate the tumor region. However, there may still be visual noise in the segmented images, which is addressed by applying the Parallel non-Local mean (PNLM) filter to enhance image quality.

The use of the U-Net architecture, a modern DL convolutional Neural Network, further enhances the performance of the proposed brain tumor segmentation model due to its effectiveness in segmenting and classifying tumors in biomedical images. Overall, the proposed work aims to overcome the challenges faced by existing brain tumor detection models by integrating advanced techniques such as Snake segmentation, PNLM filter, and U-Net architecture. By combining these methods, the new approach seeks to improve the accuracy and efficiency of tumor segmentation and classification, ultimately leading to better outcomes in early detection and treatment of brain tumors. The rationale behind choosing these specific techniques lies in their proven effectiveness in addressing the issues of noise reduction, image segmentation, and classification accuracy, thus providing a comprehensive solution to the limitations observed in current models.

The Gaussian filter is utilized in the pre-processing phase to eliminate noise from MR images, retaining only important data. The PNLM filter is then applied to further enhance image quality by reducing visual noise in segmented images. The Active Contour algorithm, specifically the Snake segmentation technique, is employed for accurately separating tumor regions from the rest of the image. The U-Net architecture, a modern DL convolutional Neural Network based classifier, is integrated into the system to improve the performance of brain tumor segmentation by effectively segmenting and classifying tumors in biomedical images. Overall, these algorithms work together to reduce Mean Square Error (MSE) values and improve the efficiency of the brain tumor detection model.
