Tumors are formed in brain due to the uncontrolled development of cells. These tumors can be cured if it is timely detected and by proper medication. This article proposes a computer‐aided automatic detection and diagnosis of meningioma brain tumors in brain images using Adaptive Neuro Fuzzy Inference System (ANFIS) classifier. The proposed system consists of feature extraction, classification, and segmentation and diagnosis sections. In this article, Grey level Co‐occurrence Matric (GLCM) and Grid features are extracted from the brain image and these features are classified using ANFIS classifier into normal or abnormal. Then, morphological operations are used to segment the abnormal regions in brain image. Based on the location of these abnormal regions in brain tissues, the segmented tumor regions are diagnosed.

Abnormal growth of cells in brain leads to the formation of tumors in brain. The earlier detection of the tumors in brain will save the life of the patients. Hence, this article proposes a computer‐aided fully automatic methodology for brain tumor detection using Co‐Active Adaptive Neuro Fuzzy Inference System (CANFIS) classifier. The internal region of the brain image is enhanced using image normalization technique and further contourlet transform is applied on the enhanced brain image for the decomposition with different scales. The grey level and heuristic features are extracted from the decomposed coefficients and these features are trained and classified using CANFIS classifier. The performance of the proposed brain tumor detection is analyzed in terms of classification accuracy, sensitivity, specificity, and segmentation accuracy.

We propose a novel recurrent network-based HDR deghosting method for fusing arbitrary length dynamic sequences. The proposed method uses convolutional and recurrent architectures to generate visually pleasing, ghosting-free HDR images. We introduce a new recurrent cell architecture, namely Self-Gated Memory (SGM) cell, that outperforms the standard LSTM cell while containing fewer parameters and having faster running times. In the SGM cell, the information flow through a gate is controlled by multiplying the gate's output by a function of itself. Additionally, we use two SGM cells in a bidirectional setting to improve output quality. The proposed approach achieves state-of-the-art performance compared to existing HDR deghosting methods quantitatively across three publicly available datasets while simultaneously achieving scalability to fuse variable length input sequence without necessitating re-training. Through extensive ablations, we demonstrate the importance of individual components in our proposed approach. The code is available at https://val.cds.iisc.ac.in/ HDR/HDRRNN/index.html.

An advancing advancement in the condition ofworkmanship improvement AI envision an earnest leisure activity inside the picture dealing with bundles, for instance, biomedical, satellite television for pc photograph getting sorted out, manufactured Intelligence, as a case, question id and certification, etc. In around the world, diabetic retinopathy endured patients growing hugely. Similarly, the reality of the circumstance is most extreme all around planned level couldn't wreck right down to regular eye inventive and perceptive. Broadening need of final product a diabetic retinopathy seeing that soonest would perhaps stops inventive and farsighted disaster for delayed diabetes seeing regardless of the way that endured younger's'. Truth of the diabetic retinopathy disease depends absolutely upon a closeness of smaller scale aneurysms, exudates,neovascularization, Hemorrhages. Experts are coordinated the ones diabetic retinopathy in to five levels, as an example, typical, unstable, moderate, absurd Non-proliferative (NPDR) or Proliferative diabetic retinopathy tolerant (PDR). An organized gigantic becoming more acquainted with methodology, as an occasion, Deep Convolutional Neural people group (DCNN) convey high accuracy inside way of development of those ailments through spatial examination. A DCNN is secured puzzling shape incited further from human seen openings. Among extra regulated figurings secured, composed course of movement is to locate a superior and advanced procedure than depicting the fundus picture with little pre-getting readied systems. We predicted developing surpassed on through utilizing techniques for dropout layer approachs yield sort of 94-96 rate accuracy. In like manner, it attempted with substantive databases, for instance, STARE, power; kaggle fundus pictures datasets are open clearly
