Lokesh Kumar Boran · International Journal for Research in Applied Science and Engineering Technology · 2024
Image classification, a fundamental task in computer vision, has undergone significant evolution over the years, driven by advancements in deep learning and machine learning techniques. This paper presents a comprehensive survey of image classification techniques, covering its journey from early methods to state-of-the-art approaches and future directions. We delve into the fundamentals of image classification, including traditional methods and the pivotal role of Convolutional Neural Networks (CNNs). The survey explores advanced techniques such as transfer learning, attention mechanisms, and multimodal learning, along with their applications across various domains including healthcare, autonomous vehicles, social media, and more. Additionally, future trends and directions in image classification are discussed, focusing on weakly supervised learning, multimodal learning, continual learning, and ethical considerations. Through this survey, we aim to provide insights into the past, present, and future of image classification, highlighting its significance, challenges, and promising avenues of research and application.
