“…The outcome indicates that the features learned are more capable of MR prostate segmentation. The study of Zawish, Siyal, Ahmed, Khalil, & Memon (2019) also seek to detect brain tumors by segmentation which is considered a challenging task due to the overlapping of tissues. The dataset used was MRI images from Brain Atlas research.…”

“…Although these integrated functions are incredibly robust for sophisticated medical images, they suffer in accuracy against the contour curve's initialization.. The Chan-Vese model as a variant of the region-based active contour models has gained considerable interest in various image segmentation techniques (Zawish, Siyal, Ahmed, Khalil, & Memon, 2019) despite the generally known problem. Extensive investigations has been made in recent years with their integration to Computer-Aided Detection (CAD) systems for tumor segmentation making it an interesting tool to further investigate their performance across selected tumour cells in this study.…”

This study aims to analyze the Chan-Vese model's performance using a variety of tumor images. The processes involve the tumors' segmentation, detecting the tumors, identifying the segmented tumor region, and extracting the features before classification occurs. In the findings, the Chan-Vese model performed well with brain and breast tumor segmentation. The model on the skin performed poorly. The brain recorded DSC 0.6949903, Jaccard 0.532558; the time elapsed 7.389940 with an iteration of 100. The breast recorded a DSC of 0.554107, Jaccard 0.383228; the time elapsed 9.577161 with an iteration of 100. According to this study, a higher DSC does not signify a well-segmented image, as the breast had a lower DSC than the skin. The skin recorded a DSC of 0.620420, Jaccard 0.449717; the time elapsed 17.566681 with an iteration of 200.

Accurate identification of tumor in brain is a challenging task in medical image processing and diagnosing the tumor with the use of Magnetic Resonance Image (MRI). So, identification tumor plays important role and there are many traditional segmentation methods which gives output, but it may or may not be accurate. So in this paper we compared two models which are segmentation with fusion and segmentation without fusion by comparing their performance metrics we can conclude which model gives more accurate performance metrics and is more preferable for Processing of image which helps to cure the tumor. The MRI grey scale image-based segmentation is a compound task because of unpredictability of brain tumors. In this clustering and segmentation methods are used. The main aim of this work is to compare two referable models, and which has better performance metrics where includes PSNR, MSE, SSIM, DC and gives the preferable model.

“…However, aforementioned deep learning based SR techniques have shown sub-optimal performance on medical images particularly for different types of modalities. Several medical imaging analysis tasks such as tumor segmentation [18] and lesion detection [19] are essentially hindered by the substandard HR output with blurred edges.…”

Multimodal medical images are widely used by clinicians and physicians to analyze and retrieve complementary information from high-resolution images in a non-invasive manner. The loss of corresponding image resolution degrades the overall performance of medical image diagnosis. Deep learning based single image super resolution (SISR) algorithms has revolutionized the overall diagnosis framework by continually improving the architectural components and training strategies associated with convolutional neural networks (CNN) on low-resolution images. However, existing work lacks in two ways: i) the SR output produced exhibits poor texture details, and often produce blurred edges, ii) most of the models have been developed for a single modality, hence, require modification to adapt to a new one. This work addresses (i) by proposing generative adversarial network (GAN) with deep multi-attention modules to learn high-frequency information from low-frequency data. Existing approaches based on the GAN have yielded good SR results; however, the texture details of their SR output have been experimentally confirmed to be deficient for medical images particularly. The integration of wavelet transform (WT) and GANs in our proposed SR model addresses the aforementioned limitation concerning textons. The WT divides the LR image into multiple frequency bands, while the transferred GAN utilizes multiple attention and upsample blocks to predict high-frequency components. Moreover, we present a learning technique for training a domain-specific classifier as a perceptual loss function. Combining multi-attention GAN loss with a perceptual loss function results in a reliable and efficient performance. Applying the same model for medical images from diverse modalities is challenging, our work addresses (ii) by training and performing on several modalities via transfer learning. In comparison to existing state-of-the-art approaches, we validate our proposed SR network on two medical datasets and achieve promising results in terms of SSIM and PSNR.
