Towards Low-Cost Classification for Novel Fine-Grained Datasets

Fine-grained categorization is an essential field in classification, a subfield of object recognition that aims to differentiate subordinate classes. image classification concentrates on distinguishing between similar, hard-to-differentiate types or species, for example, flowers, birds, specific animals such as dogs cats, and identifying airplane makes models. An important step towards fine-grained the acquisition datasets baselines; hence, we propose holistic system two novel datasets, including reef fish butterflies, classification. The butterflies can be imaged at various locations plane; thus, causing variations due translation, rotation, deformation multiple directions induce variations, depending device’s position, scales different. We evaluate traditional algorithms based quantized rotation scale-invariant local features convolutional neural networks (CNN) using their pre-trained models extract features. comprehensive evaluation shows CNN calculated outperform rest representations. proposed prove instrumental purposes, education, conservation, scientific research. codes, models, dataset are publicly available.
