  • عنوان البحث : Integrating the Kernel Method to Autonomous Learning Multi-Model Systems for Online Data

    ملخص البحث :

    We present a novel and simple approach to incorporate the kernel function method to a recently proposed autonomous learning system (ALS). An ALS can learn online from data streams without any need to offline batch training and it is both memory and computational power efficient. We have codenamed our approach: KALMMo for Kernelized Autonomous Learning Multi Model system. Using the Radial Basis Function (RBF) kernel, we have tested the performance of KALMMo using four well-known and challenging datasets and compared the results to other well established algorithms. Our results have shown that KALMMo performed at least as good as other competitive approaches or even better. Its training time is linearly proportional to the number of instances of a dataset and that the training time is better by an order of magnitude to the nearest competitor. KALMMo shows interesting feature to several applications including big data and machine learning classification. The performance of the proposed systems should be tested with other types of kernel functions.

  • عنوان البحث : Histogram Features Extraction for Edge Detection Approach

    ملخص البحث :

    An edge is where an image’s intensity values rapidly change from low to high-intensity values or vice versa. The edge itself is at the midpoint of this change. Edge detection remains a challenge in computer vision despite recent advances. It cannot be applied to an image with excessive brightness and contrast. This paper produces a new method based on the standard deviation histogram feature to reduce the onerousness. The proposed method aims to prepare the input image for the edge detection approaches by performing a histogram feature extraction. The main characteristics of the proposed approach are simplicity and functionality. The authors utilize twenty MATLAB standard images as well as ADNI brain images. The authors use the Canny edge detection method to defect edges from the proposed method. The authors use edge detection evaluation metrics such as Figure of Merit (FOM), Structural Similarity Index Metric (SSIM), Peak Signal to Noise Ratio (PSNR), and Mean Square Error (MSE) measures for evaluating and justifying edge quality. The experimental results show that the proposed method performs better in visual and statistical edge quality than both classical and fractional-order edge detection methods.

  • عنوان البحث : Soft Edge Detection by Mamdani Fuzzy Inference of Color Image

    ملخص البحث :

    One of the most common image operation analyses is the edge detection technique. Edge detection is used for shaping the edge of an image. Also, it is used for enhancing images. This paper presents a new approach to detecting the edge of color image using the Mamdani fuzzy inference classifier based on the Fuzzy Set Membership Function (FSMF). Here, Gaussian Curve Membership Function (GCMF) is used as a FSMF. GCMF is used for each class to assign that class to each pixel. In this approach, two windows/filters are used in size (1x2) and (2x1). Several standard color images are used to test our proposed algorithm (City, Jelly_cc11, Baboon, Lena, and Peppers). In order to parametric evaluation of selected images, Peak Signal Noise Ratio (PSNR) and Mean Square Error (MSE) are considered. However, the performance of our proposed algorithm compared with other well-known approaches (Canny, Prewitt, and Sobel) is somehow very similar but significantly faster.

  • عنوان البحث : Acute lymphoblastic leukemia image segmentation based on modified HSV model

    ملخص البحث :

    Image segmentation is a critical step in computer-aided diagnosis that could speed up Leukemia detection. Leukemia is a cancer of the blood that has a reputation for being particularly lethal. Based on the immunohistochemical method, the leukocytes can be manually counted in a stained peripheral blood smear image to detect Acute Lymphoblastic Leukemia (ALL). Regrettably, the manual diagnosis process takes about 3 to 24 hours to complete, which is insufficient. This paper introduced a new and straightforward ALL image segmentation approach based on color image transformation. First, Leukemia, ALL-IDB1, ALL-IDB2, and ALL image datasets were used in this paper. The Leukemia dataset includes 208 ALL-IDB1 and ALL-IDB2 images, while The ALL dataset has 3256 images. Next, we use the HSV model to transform ALL images. In addition, we modified the HSV model by pre-processing the saturation channel for better results. Then, the pre-processed images were segmented based on a fixed threshold. After that, various metrics are utilized to measure the output of the proposed method. Finally, the proposed methodology is compared to currently used benchmarks. The proposed method outperforms previous approaches regarding accuracy, specificity, sensitivity, and time. In addition, results show that the proposed technique improves performance measures significantly.

  • عنوان البحث : A novel medical image enhancement technique based on hybrid method

    ملخص البحث :

    Medical images are a specific type of image that can be used to diagnose disease in patients. Critical uses for medical images can be found in many different areas of medicine and healthcare technology. Generally, the medical images produced by these imaging methods have low contrast. As a result, such types of images need immediate and fast enhancement. This paper introduced a novel image enhancement methodology based on the Laplacian filter, contrast limited adaptive histogram equalization, and an adjustment algorithm. Two image datasets were used to test the proposed method: The DRIVE dataset, forty images from the COVID-19 Radiography Database, endometrioma-11, normal-brain-MRI-6, and simple-breast-cyst-2. In addition, we used the robust MATLAB package to evaluate our proposed algorithm's efficacy. The results are compared quantitatively, and their efficacy is assessed using four metrics: Peak Signal to Noise Ratio (PSNR), Mean Squared Error (MSE), Contrast to Noise Ratio (CNR), and Entropy (Ent). The experiments show that the proposed method yields improved images of higher quality than those obtained from state-of-the-art techniques regarding MSE, CNR, PSNR, and Ent metrics.

  • عنوان البحث : Melanoma Skin Cancer Classification based on CNN Deep Learning Algorithms

    ملخص البحث :

    Melanoma, the deadliest form of skin cancer, is on the rise. The goal of this study is to present a deep learning system implementation for the detection of melanoma lesions on a server equipped with a graphics processing unit (GPU). When applied by a dermatologist, the recommended method might aid in the early detection of this kind of skin cancer. Evidence shows that deep learning may be used in a variety of settings to successfully extract patterns from data such as signals and images. This research presents a convolution neural network–based strategy for identifying early-stage melanoma skin cancer. Images are input into a deep learning model known as a convolutional neural network (CNN) that has already been pre-trained. The CNN classifier, which is trained with large amounts of data, can discriminate between malignant and nonmalignant melanoma. The method's success in the lab bodes well for its potential to aid dermatologists in the early detection of melanoma. However, the experimental results show that the proposed technique excels beyond the state-of-the-art methods in terms of diagnostic accuracy.

  • عنوان البحث : Design a Crime Detection System based Fog Computing and IoT

    ملخص البحث :

    The Internet of Things (IoT) is a cutting-edge innovation that facilitates the cost-effective development of smart system architectures. Although current regulations necessitate installing an analog fire alarm system, such a system lacks the intelligence to instantly notify the appropriate parties in a timely fashion. In addition, since people are not always present, an analog fire alarm will not be able to prevent immediate danger or damage in the event of a fire. Therefore, the incident must be reported as soon as possible to the appropriate party in order to lessen the impact of a fire. In this study, we suggest a smart fire-alarm system made of a fire sensor and a sound sensor that can both detect fire and noise as well as the status of the analog fire alarm system to ascertain whether the analog fire alarm system is operational. We first tested our proposed smart fire alarm system to determine its effectiveness before putting it into use. From there, we ran experiments to determine how well it worked. The outcomes show that the system is trustworthy in a range of scenarios.

  • عنوان البحث : Retinal blood vessel segmentation based on the gabor filter and optimized top-hat morphology

    ملخص البحث :

    Retinal fundus images, specifically the morphology of blood vessels, are valuable diagnostic tools for diseases such as hypertension, diabetic retinopathy, and glaucoma. Modern ophthalmic diagnostic methods rely on the results of analyses of retinal images, and the quality of these analyses depends on the precision with which blood vessels in the retina are segmented. Retinal blood vessel segmentation methods all rely on a process known as contrast enhancement. Having uniform contrast throughout the image is crucial to the accuracy of the segmentation. An essential step in Computer-Aided Diagnosis (CAD) for many eye conditions is the automatic segmentation of retinal blood vessels. Medical analysis and disease diagnosis rely on segmenting thin and thick retinal vessels. This article proposes a new method for accurate vessel segmentation to overcome the difficulties already described in the literature. However, the proposed method is based on the Gabor filter and optimized top-hat morphology techniques. The proposed method is divided into three main stages, image pre-processing, segmentation, and post-processing. A common and public dataset, DRIVE, is employed to evaluate our proposed method. In addition, three metrics are utilized to evaluate the proposed method: accuracy, sensitivity, and specificity. As a result, compared to the state-of-the-art method, the proposed method resulted in significantly improved segmentation accuracy, achieving an accuracy of 96.55%, a sensitivity of 79.36%, and a specificity of 98.20% for the training set. Also, the final results of the proposed method achieved 95.95%, 74.24%, and 98.05% for the testing set’s accuracy, sensitivity, and specificity, respectively.
