The brain tumor detection is usually done in Magnetic Resonance Imaging (MRI) of the human brain. An automated model is framed to identify tumor pixels in method for detecting and image. This proposed method contains the following\u0000 modules as enhancement, transformation, feature extraction, classifications and segmentation. The Oriented Local Histogram Equalization (OLHE) method is applied on the brain MRI images in order to enhance the pixel intensity in boundary regions. This enhanced brain image is transformed to\u0000 multi orientation image using Gabor transform with respect to various scale and orientation of pixels. Then, set of features (Higher Order Spectra (HOS), Gradient, Grey Level Co-occurrence Matrix (GLCM), Local Binary Pattern (LBP) and Curvelet) are extracted from this Gabor transformed image\u0000 and these features are further trained and classified into benign or malignant using Adaptive Neuro Fuzzy Inference (ANFIS) classification approach. Finally, morphological algorithm is used for segmenting the tumor regions in the classified responses. MATLAB R2018 version is used in this paper\u0000 to simulate the proposed algorithm for brain tumor detection. This proposed system achieves 98.6% of sensitivity, 99.5% of specificity and 99.4% of segmentation accuracy.","PeriodicalId":393031,"journal":{"name":"J.

CBT combined with virtual reality (VR) is a new and beneficial psychotherapeutic intervention\u0000 for patients and violent offenders with impulse-anger control problems and alcohol dependence. This clinical study evaluated the effects of the “anger management virtual reality cognitive behavior therapy (AM-VR-CBT)” and motivational interviewing (MI) intervention program on quantitative\u0000 electroencephalography (QEEG) mapping patterns among violent offenders with alcohol dependence (N = 29) in the National Probation Service. A clinical sample of twenty-nine violent offenders with alcohol dependence, who were evaluated and diagnosed with destructive and impulse-control\u0000 disorders (DICD), underwent AM-VR-CBT combined with MI. The sessions lasted 150 minutes (AM-VR-CBT: 90 min; MI: 60 min) and were conducted twice a week for three weeks (six sessions). The intervention outcomes were measured using advanced QEEG brain mapping and standardized neurocognitive,\u0000 emotional, and behavioral inventories, including the Alcohol Dependence Scale (ADS), the Obsessive Compulsive Drinking Scale (OCDS), the Readiness to Change Questionnaire (RTCQ), the Barratt Impulsiveness Scale-II (BIS-II), the Beck Anxiety Inventory (BAI), the Beck Depression Inventory-Second\u0000 Edition (BDI-2), and the State-Trait Anger Expression Inventory-2 (STAXI-2), to identify neuro-psycho-physiological changes in violent offenders with alcohol dependence. The Wilcoxon signed-rank test was used at p < 0.05. The intervention showed significant improvements and healthy\u0000 behavioral changes related to obsessive drinking thoughts, compulsive drinking behaviors, attentional control, intrinsic motivation, worry, anxiety, depression, impulse-anger control issues, aggressive behaviors, over-control, interpersonal relationships, self-efficacy, self-reflection, self-inhibition,\u0000 creativity, mental navigation/imagery, and episodic memory retrieval among violent offenders with alcohol dependence. Therefore, the results demonstrate the efficacy of the novel and promising clinical evidence-based implementation of the AM-VR-CBT + MI program intervention for non-invasive\u0000 neuromodulation and related neuro-psycho-physiological, neurocognitive, emotional, and behavioral changes among violent offenders demonstrating alcohol dependence, impulse-anger control, and aggressive behaviors.","PeriodicalId":393031,"journal":{"name":"J.

To share this multimedia content across internet, storage and transmission become a challenge because of its huge volume. New compression techniques\u0000 are being continuously introduced to circumvent this issue. Compressive sensing (CS) is a new paradigm in signal compression. Block based compressive sensing (BCS) is a standard and commonly used technique in color image compression. However, BCS suffers from block artifacts and during transmission,\u0000 mistakes can be introduced to affect the BCS coefficients, degrading the reconstructed image’s quality. The performance of BCS at low compression ratios is also poor. To overcome these limitations, without dividing the image into blocks, the image matrix is considered as a whole and\u0000 compressively sensed by segment based compressive sensing (SBCS). This is a novel strategy that is offered in this article, for efficient compression of digital color images at low compression ratios. Metrics of performance The peak signal to noise ratio (PSNR), the mean structural similarity\u0000 index (MSSIM), and the colour perception metric delta E are computed and compared to those obtained using block-based compressive sensing (BBCS). The results show that SBCS performs better than BBCS.","PeriodicalId":393031,"journal":{"name":"J.

The early diagnosis of DR is essential to avoid painless blindness. The conventional DR diagnosis is manual and requires skilled Ophthalmologists. The Ophthalmologist’s analyses are subjective\u0000 to inconsistency and record maintenance issues. Hence, there is a need for other DR diagnosis methods. In this paper, we proposed an AdaBoost algorithm-based ensemble classification approach to classify DR grades. The major objective of the proposed approach is an enhancement of DR classification\u0000 performance by using optimized features and ensemble machine learning techniques. The proposed method classifies different grades of DR using the Meyer wavelet and retinal vessel-based features extracted from multiple regions of interest of the retina. To improve the predictive accuracy, we\u0000 used a Bayesian algorithm to optimize the hyper-parameters of the proposed ensemble classifier. The proposed DR grading model was constructed and evaluated by using the MESSIDOR fundus image dataset. In evaluation experiment, the classification outcome of the proposed approach was evaluated\u0000 by the confusion matrix and receiver operating characteristic (ROC) based metrics. The evaluation experiments show that the proposed approach attained 99.2% precision, 98.2% recall, 99% accuracy, and 0.99 AUC. The experimental findings also indicate that the proposed approach’s classification\u0000 outcome is significantly better than that of state of art DR classification methods.","PeriodicalId":393031,"journal":{"name":"J.
