Special Issue Information

Dear Colleagues,

This Special Issue focuses on exploring the diverse realm of multimedia signal processing, covering the various theories, methods, and applications in this dynamic field. With a primary emphasis on addressing existing challenges, this collection of research papers spans multiple topics, including acoustic signal processing, image processing, IoT, and machine learning.

In the domain of acoustic signal processing, the Special Issue showcases advancements in areas such as audio coding, speech recognition, and music analysis. It presents innovative techniques for audio quality enhancement, feature extraction from sound, and efficient audio compression algorithms.

Within image processing, the Special Issue highlights breakthroughs in image and video coding, content analysis, and computer vision. Researchers contribute novel approaches for tasks such as image denoising, object detection and recognition, and image segmentation, pushing the boundaries of visual data processing.

Furthermore, this Special Issue acknowledges the growing influence of the Internet of Things (IoT) and machine learning in multimedia signal processing. It accepts studies on IoT-based multimedia systems, sensor data fusion, and intelligent multimedia analytics. Contributions related to machine learning algorithms for multimedia analysis, classification, and retrieval are also featured, illustrating the impact of AI techniques on multimedia signal processing.

By gathering state-of-the-art research in these areas, this Special Issue aims to foster collaboration, inspire innovation, and pave the way for future advancements in multimedia signal processing.

The following paper presents a solution to the problem of offline recognition of Japanese characters. Minutiae and other features extractable from handwriting images have been used to recognize individual characters. The solution presented by the authors uses minutiae to recognise single Japanese characters. Due to the complexity of this typeface, the solution presented can be used to recognise archaic characters, from old documents or also works of art. Neural Networks and hybrid classifiers based on five basic types of classifiers, i.e., k-nearest neighbour method, decision trees, support vector machine, logistic regression and Gaussian Naive Bayes classifier have been developed for classification. The study was conducted on Hiragana, Katakana and Kanji characters (ETL9G Database). The accuracy value obtained was 99.934%. The authors present what is probably the first algorithm using minutiae to recognize Japanese handwriting. Full article
