Existing vision-based methods, primarily leveraging Convolutional Neural Networks (CNNs), often achieve high performance but are hindered by high computational complexity, making real-time deployment on edge devices challenging. Moreover, the diversity and similarity among fruit varieties, along with imbalanced fruit datasets, pose significant obstacles to general-purpose deep learning algorithms. To address these challenges, we propose the Multi-Scale Attention Pyramid Vision Transformer (MSAPVT) alongside an enhanced version of the Fru92 dataset. Our MSAPVT introduces four innovative improvements: attention enhancement, dimension adjustment, multi-scale feature aggregation and loss function improvement. Firstly, the Hybrid Attention Module (HAM) is designed for better refining the multi-level features of the Pyramid Vision Transformer v2 (PVTv2). Secondly, the Dimension Adjustment Layer (DAL) is designed for increasing the weight of the high-level features. Thirdly, the multi-scale feature aggregation strategy is introduced to fuse multi-scale complementary features. Finally, the KL-divergence loss is added for enhancing the difference between multi-scale features. These innovations enable MSAPVT to capture fine-grained details in fruit images, generating highly discriminative representations with slight low model complexity. Our model achieves the best results on the Fru92 and Fru92s datasets, with Top-1 Acc. of 91.40% and 94.29%, and Top-5 Acc. of 98.95% and 99.55%, respectively. In the end, an approachable and efficient fruit classification system based on MSAPVT is devised for potential applications. The improved dataset is available at https://github.com/iamraoyao/MSAPVT-Inference-Demo.</p></div>","PeriodicalId":631,"journal":{"name":"Journal of Food Measurement and Characterization","volume":"18 11","pages":"9233 - 9251"},"PeriodicalIF":2.9,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142565888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results revealed similarities in mineral content and crystalline structures, while the higher fat content in SF presents potential advantages in mouthfeel and flavor. SF exhibits a notably shorter peak viscosity (506.6 m.Pa) compared to PF (616 m.Pa), indicative of its rapid gelatinization kinetics and making it advantageous in rapid thickening products such as instant sauces or soups. The irregular and agglomerated structure of SF, compared to the uniform oval shape of PF, was revealed by SEM. Similar functional groups were observed in both tubers, as revealed by FTIR. Amino acid profiles highlight distinctions in protein quality, with SF showing higher a glutamic acid content and limited sulfur-containing amino acids and aromatic amino acids. The results indicated that a combination of 60% SF and 40% Refined Wheat Flour (RWF) had the highest acceptability. As the proportion of PF increased, a progressive reduction in hardness was observed. The addition of SF (40%) exhibited increased hardness (2971.95 g) and adhesiveness (89.35 g.s), contributing to higher gumminess (544.36 g) and chewiness (398.22 g).
