The classification of garbage types is an important issue in today's world, and its proper implementation can contribute to environmental conservation and improved efficiency of recycling processes. Unfortunately, the classification of garbage types is currently predominantly performed through human supervision, which leads to high errors and environmental risks. It is crucial to automate this procedure utilizing machine vision methods as a result. This research proposes a revolutionary deep learning-based strategy for classifying domestic waste. The suggested method uses deep learning methods to extract information from images. The Capuchin Search Algorithm (CapSA) is used to improve the hyperparameters of the convolutional neural network (CNN) used as the feature extraction model. Furthermore, for categorizing the retrieved features from the CNN model, a hybrid learning model based on Error-Correcting Output Codes (ECOC) and Artificial Neural Networks (ANN) is used. The classification accuracy may be successfully increased by using this hybrid model, and the benefit becomes more pronounced as the number of target categories rises. The TrashNet and HGCD databases were used to assess the suggested method's effectiveness, and its results in waste type detection were contrasted with those of earlier techniques. Based on the study findings, the suggested approach can identify trash types with an accuracy of 98.81 % and 99.01 % on the TrashNet and HGCD databases, respectively. This is at least a 1.46 % improvement over earlier approaches. The study's conclusions validate that the suggested strategy may be used in real-world scenarios and show how successful the approaches used in it are.
垃圾类型分类是当今世界的一个重要问题,其正确实施有助于环境保护和提高回收过程的效率。不幸的是,目前垃圾类型分类主要通过人工监督进行,这导致了高误差和环境风险。因此,利用机器视觉方法实现这一过程的自动化至关重要。本研究提出了一种基于深度学习的革命性策略来对生活垃圾进行分类。所建议的方法使用深度学习方法从图像中提取信息。卷尾猴搜索算法(CapSA)用于优化作为特征提取模型的卷积神经网络(CNN)的超参数。此外,为了对从CNN模型检索到的特征进行分类,使用了一种基于纠错输出码(ECOC)和人工神经网络(ANN)的混合学习模型。使用这种混合模型可以成功提高分类准确率,并且随着目标类别数量的增加,这种优势会更加明显。使用TrashNet和HGCD数据库评估所建议方法的有效性,并将其在垃圾类型检测方面的结果与早期技术的结果进行对比。根据研究结果,所建议的方法在TrashNet和HGCD数据库上分别能够以98.81%和99.01%的准确率识别垃圾类型。这比早期方法至少提高了1.46%。该研究的结论验证了所建议的策略可以应用于实际场景,并展示了其中所使用方法的成功之处。
