Dry Fish Image dataset: Data-driven analysis and deep learning-based classification

This article presents a dry fish image dataset framework to support data-driven research in computer vision, machine learning and Deep Learning. This dataset collected from a multiple market of dry fish in Dhaka, which shows that how different they look, how they are handled, and how they are presented in real world. Images were acquired using consumer-grade mobile cameras under natural lighting conditions to reflect practical deployment scenarios. The collection process purposefully incorporated variations in lighting, background clutter, camera angles, distances, and obstructions to augment data diversity. We got permission to take all the pictures and put them in a consistent naming and folder structure. The dataset has high-quality RGB images of twelve different types of dry fish, such as Bashpata, Chanda, Chapila, Chewa, Churi, Loitta, Shukna Feuwa, Shundori, Chingri, Kachki, Narkeli, and Puti Chepa. Each class includes dry fish species that are commonly traded and shows natural differences in size, texture, color, and drying patterns within the class. We looked at in the data and put them in groups by hand to make sure they were all in the same class by taking help of expert. We did some simple preprocessing, such as getting rid of duplicates and making sure that the formats were the same, all while keeping the data's original visual features.You can use this dry fish dataset again for things like classifying images, extracting features, analyzing data imbalance, benchmarking data augmentation, and visualizing explainable artificial intelligence. It could also help with research on how to recognize food with few resources, automate markets, digitize supply chains, and use mobile devices for inspections. The way the dataset is set up makes it easy to work with well-known deep learning frameworks. It can also be added to with more classes or metadata, making it useful for both academic research and practical development in smart food systems and fisheries informatics.
