Abstract Prostate cancer is the one of most dominant among males. It represents leading death causes worldwide. Due to current evolution artificial intelligence in medical imaging, deep learning has been successfully applied diseases diagnosis. However, recent studies prostate classification suffers from either low accuracy or lack data. Therefore, present work introduces a hybrid framework for early and accurate segmentation using learning. The proposed consists two stages, namely stage stage. In stage, 8 pretrained convolutional neural networks were fine-tuned Aquila optimizer used classify patients normal ones. If patient diagnosed with cancer, segmenting cancerous spot overall image U-Net can help diagnosis, here comes importance trained on 3 different datasets order generalize framework. best reported accuracies are 88.91% MobileNet “ISUP Grade-wise Cancer” dataset 100% ResNet152 “Transverse Plane Dataset” precisions 89.22% 100%, respectively. model gives an average AUC 98.46% 0.9778, respectively, “PANDA: Resized Train Data (512 × 512)” dataset. results give indicator acceptable performance

Abstract More than 5% of the people around world are deaf and have severe difficulties in communicating with normal according to World Health Organization (WHO). They face a real challenge express anything without an interpreter for their signs. Nowadays, there lot studies related Sign Language Recognition (SLR) that aims reduce this gap between as it can replace need interpreter. However, challenges facing sign recognition systems such low accuracy, complicated gestures, high-level noise, ability operate under variant circumstances generalize or be locked limitations. Hence, many researchers proposed different solutions overcome these problems. Each language has its signs very challenging cover all languages’ The current study objectives: (i) presenting dataset 20 Arabic words, (ii) proposing deep learning (DL) architecture by combining convolutional neural network (CNN) recurrent (RNN). suggested reported 98% accuracy on presented dataset. It also 93.4% 98.8% top-1 top-5 accuracies UCF-101

Abstract The increase in eye disorders among older individuals has raised concerns, necessitating early detection through regular examinations. Age-related macular degeneration (AMD), a prevalent condition over 45, is leading cause of vision impairment the elderly. This paper presents comprehensive computer-aided diagnosis (CAD) framework to categorize fundus images into geographic atrophy (GA), intermediate AMD, normal, and wet AMD categories. crucial for precise age-related enabling timely intervention personalized treatment strategies. We have developed novel system that extracts both local global appearance markers from images. These are obtained entire retina iso-regions aligned with optical disc. Applying weighted majority voting on best classifiers improves performance, resulting an accuracy 96.85%, sensitivity 93.72%, specificity 97.89%, precision 93.86%, F1 ROC 95.85%, balanced 95.81%, sum 95.38%. not only achieves high but also provides detailed assessment severity each retinal region. approach ensures final aligns physician’s understanding aiding them ongoing follow-up patients.
