A Hybrid Memetic Algorithm (Genetic Algorithm and Great Deluge Local Search) With Back-Propagation Classifier for Fish Recognition
The aim of this study is to establish a hybrid method to optimize the performance of back-propagation classifier for fish classification by using Memetic Algorithm (MA) (genetic algorithm and great deluge local search). This is to be performed by utilizing the ability of memetic algorithm to optimize the parameters (weight and bias) of the back-propagation classifier (PBC). Recognizing an isolated pattern of interest (fish) in the image is based on robust features extraction. These features are extracted based on color signature measurements that are extracted by Gray histogram technique and Level Co-Occurrence Matrix (GLCM) method. The typical Back Propagation Classifier (BPC) has the slow practice speed and easy for running into local minimum disadvantages. The new system prototype will help in resolving such disadvantages.
Results: The new system starts by acquiring an image containing pattern of fish, then the image features extraction is performed relying on color signature measurements. The system has been applied on 20 different fish families, each family has a different number of fish types and the used sample consists of 610 distinct fish images. These images are divided into two datasets: 410 training images and 200 testing images. The hybrid memetic algorithm(Genetic algorithm and Great Deluge Local Search) with back-propagation classifier (HGAGD-BPC) has outperformed the BPC method and previous methodologies by obtaining better quality results but with a high cost of computational time compared to the BPC method. The overall accuracy obtained using the traditional BPC was 84%, while the overall accuracy obtained by the HGAGD-BPC was 93.5% on the test dataset used.
Conclusion: A powerful classifier for fish images classification has been developed. The new hybrid classifier is successfully designed and implemented and has performed efficiently to make a decision without any problems. Eventually, the classifier is able to categorize the given fish into its cluster (poison or non-poison fish) and categorizes it into its family.
