Introduction

The classification of fish species is a crucial task in the field of fisheries, as it plays a significant role in the management and conservation of fish populations. However, the traditional method of classification, which relies on eye observation and assumptions based on knowledge, has several limitations, including speed and accuracy. Therefore, a more sophisticated approach is needed to classify fish species effectively and efficiently. In this study, we propose the use of image processing and probabilistic neural networks (PNN) to classify three species of fish included in the Scombridae family, namely skipjack fish, tuna, and tuna that are in land (out of water).

Background

The Scombridae family is one of the largest families of fish, with over 50 species. However, the classification of fish species within this family is often difficult due to the similarities in their physical characteristics. The traditional method of classification, which relies on eye observation and assumptions based on knowledge, has several limitations, including speed and accuracy. Therefore, a more sophisticated approach is needed to classify fish species effectively and efficiently.

Proposed Approach

In this study, we propose the use of image processing and PNN to classify three species of fish included in the Scombridae family. The proposed approach utilizes ROI (region of interest), which focuses on the abdomen of fish. The feature extraction process is done by combining several methods, including GIM (Geometric Invariant Moment), GLCM (Gray Level Co-Octurrence Matrix), and HSV (Hue Saturation Value).

Feature Extraction

GIM serves to capture geometric information from fish image that can help in identifying fish shapes.
GLCM is used to analyze image texture, so that it can clarify the difference between fish species based on color distribution patterns.
HSV is used to identify fish colors that can be different among the species involved.

Probabilistic Neural Network (PNN)

After the feature is extracted, the data is entered into the PNN model. This method works by building the probability function of different classes based on training data and then classifying test data based on the probability. The advantage of PNN is its ability to provide estimated uncertainty, which is useful in classification decisions that involve many variables.

Research Methodology

In this study, we used a total of 141 images, consisting of 112 images as training data and 29 images as testing data. The images were collected from various sources, including online databases and field observations. The feature extraction process was done using the combination of GIM, GLCM, and HSV methods. The PNN model was trained using the training data, and the performance of the model was evaluated using the testing data.

Research Result

Based on the research involving 112 images as training data and 29 images as testing data, this classification model shows a fairly high level of accuracy, which is 89.65%. These results indicate that the combination of feature extraction methods selected and the use of PNN as a classification method can produce accurate fish species introduction.

Benefits and Implications

This approach not only increases efficiency in the classification of fish species, but can also help researchers, fishermen, and professionals in the field of fisheries in identifying fish species more quickly and accurately. With the adoption of image processing technology and neural networks, it is expected to improve the practice of managing fisheries resources and environmental preservation better.

Future Work

By continuing to develop this technology, we can hope that there will be further improvement in the accuracy of classification, as well as the potential implementation in the ecological study and conservation of other fish species in the future. Additionally, the use of this technology can be extended to other fields, such as medicine and agriculture, where accurate classification is crucial.

Conclusion

In conclusion, this study demonstrates the effectiveness of using image processing and PNN to classify fish species. The proposed approach utilizes ROI, GIM, GLCM, and HSV methods for feature extraction, and PNN for classification. The results show a high level of accuracy, indicating that this approach can be used to classify fish species effectively and efficiently. The benefits of this approach include increased efficiency in classification, improved accuracy, and potential implementation in ecological study and conservation of other fish species.
