Measles Rash Identification Using Residual Deep Convolutional Neural Network
Measles is extremely contagious and is one of the leading causes of
vaccine-preventable illness and death in developing countries, claiming more
than 100,000 lives each year. Measles was declared eliminated in the US in 2000
due to decades of successful vaccination for the measles. As a result, an
increasing number of US healthcare professionals and the public have never seen
the disease. Unfortunately, the Measles resurged in the US in 2019 with 1,282
confirmed cases. To assist in diagnosing measles, we collected more than 1300
images of a variety of skin conditions, with which we employed residual deep
convolutional neural network to distinguish measles rash from other skin
conditions, in an aim to create a phone application in the future. On our image
dataset, our model reaches a classification accuracy of 95.2%, sensitivity of
81.7%, and specificity of 97.1%, indicating the model is effective in
facilitating an accurate detection of measles to help contain measles
outbreaks
Scaled conjugate gradient based decision support system for automated diagnosis of skin cancer
Melanoma is the most deathful form of skin cancer but early diagnosis can ensure a high rate of survival. Early diagnosis is one of the greatest challenges due to lack of experience of general practitioners (GPs). This paper presents a clinical decision support system designed for the use of general practitioners, aiming to save time and resources in the diagnostic process. Segmentation, pattern recognition, and lesion detection are the important steps in the proposed decision support system. The system analyses the images to extract the affected area using a novel proposed segmentation method. It determinates the underlying features which indicate the difference between melanoma and benign images and makes a decision. Considering the efficiency of neural networks in classification of complex data, scaled conjugate gradient based neural network is used for classification. The presented work also considers analyzed performance of other efficient neural network training algorithms on the specific skin lesion diagnostic problem and discussed the corresponding findings. The best diagnostic rates obtainedthrough the proposed decision support system are around 92%
Artificial Intelligence in Skin Cancer: A Literature Review from Diagnosis to Prevention and Beyond
Artificial Intelligence (AI) in medicine is quickly expanding, offering significant potential benefits in diagnosis and prognostication. While concerns may exist regarding its implementation, it is important for dermatologists and dermatopathologists to collaborate with technical specialists to embrace AI as a tool for enhancing medical decision-making and improving healthcare accessibility. This is particularly relevant in melanocytic neoplasms, which continue to present challenges despite years of experience. Dermatology, with its extensive medical data and images, provides an ideal field for training AI algorithms to enhance patient care. Collaborative efforts between medical professionals and technical specialists are crucial in harnessing the power of AI while ensuring it complements and enhances the existing healthcare framework. By staying informed about AI concepts and ongoing research, dermatologists can remain at the forefront of this emerging field and leverage its potential to improve patient outcomes. In conclusion, AI holds great promise in dermatology, especially in the management and analysis of Skin cancer (SC).
In this review we strive to introduce the concepts of AI and its association with dermatology, providing an overview of recent studies in the field, such as existing applications and future potential in dermatology
Skin Cancer Recognition by Using a Neuro-Fuzzy System
Skin cancer is the most prevalent cancer in the light-skinned population and it is generally caused by exposure to ultraviolet light. Early detection of skin cancer has the potential to reduce mortality and morbidity. There are many diagnostic technologies and tests to diagnose skin cancer. However many of these tests are extremely complex and subjective and depend heavily on the experience of the clinician. To obviate these problems, image processing techniques, a neural network system (NN) and a fuzzy inference system were used in this study as promising modalities for detection of different types of skin cancer. The accuracy rate of the diagnosis of skin cancer by using the hierarchal neural network was 90.67% while using neuro-fuzzy system yielded a slightly higher rate of accuracy of 91.26% in diagnosis skin cancer type. The sensitivity of NN in diagnosing skin cancer was 95%, while the specificity was 88%. Skin cancer diagnosis by neuro-fuzzy system achieved sensitivity of 98% and a specificity of 89%
Machine learning methods for histopathological image analysis
Abundant accumulation of digital histopathological images has led to the
increased demand for their analysis, such as computer-aided diagnosis using
machine learning techniques. However, digital pathological images and related
tasks have some issues to be considered. In this mini-review, we introduce the
application of digital pathological image analysis using machine learning
algorithms, address some problems specific to such analysis, and propose
possible solutions.Comment: 23 pages, 4 figure
Recent advancement in Disease Diagnostic using machine learning: Systematic survey of decades, comparisons, and challenges
Computer-aided diagnosis (CAD), a vibrant medical imaging research field, is
expanding quickly. Because errors in medical diagnostic systems might lead to
seriously misleading medical treatments, major efforts have been made in recent
years to improve computer-aided diagnostics applications. The use of machine
learning in computer-aided diagnosis is crucial. A simple equation may result
in a false indication of items like organs. Therefore, learning from examples
is a vital component of pattern recognition. Pattern recognition and machine
learning in the biomedical area promise to increase the precision of disease
detection and diagnosis. They also support the decision-making process's
objectivity. Machine learning provides a practical method for creating elegant
and autonomous algorithms to analyze high-dimensional and multimodal
bio-medical data. This review article examines machine-learning algorithms for
detecting diseases, including hepatitis, diabetes, liver disease, dengue fever,
and heart disease. It draws attention to the collection of machine learning
techniques and algorithms employed in studying conditions and the ensuing
decision-making process
Neural Network Diagnosis of Malignant Melanoma from Color Images
Malignant melanoma is the deadliest form of all skin cancers. Approximately 32,000 new cases of malignant melanoma were diagnosed in 1991 in the United States, with approximately 80% of patients expected to survive 5 years. Fortunately, if detected early, even malignant melanoma may be treated successfully, Thus, in recent years, there has been rising interest in the automated detection and diagnosis of skin cancer, particularly malignant melanoma. Here, the authors present a novel neural network approach for the automated separation of melanoma from 3 benign categories of tumors which exhibit melanoma-like characteristics. The approach uses discriminant features, based on tumor shape and relative tumor color, that are supplied to an artificial neural network for classification of tumor images as malignant or benign. With this approach, for reasonably balanced training/testing sets, the authors are able to obtain above 80% correct classification of the malignant and benign tumors on real skin tumor images
