This article presents a new real-time driver distraction detection system based on Fast R-CNN in real-time with the highest accuracy of 89%.

Our system also includes a temporal analysis module that uses long short-term memory to capture temporal relations in driver behavior. This approach provided a novel way of identifying drivers’ distractions autonomously, leading to a 30% reduction in accidents. This research enriches the knowledge base for intelligent driver assistance systems, leading to improved road safety levels worldwide.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"49 3","pages":"433 - 438"},"PeriodicalIF":1.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148380996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This model effectively addresses temporal variance, enhancing content retrieval and analysis accuracy.

This study reports the one-way programming of PCL-PLA-NFs under thermal, thermo-chemical, and hydro-thermal stimuli. In this study, inhouse prepared filaments of PCL- PLA-NFs (1/2/3% by Vol.) were exposed to thermal, thermal + H<sub>2</sub>O (hydro-thermal), and thermal + C<sub>3</sub>H<sub>6</sub>O (thermochemical) stimuli to ascertain the feasibility of the one-way programming. The study results suggest that better shape recovery was noticed in the case of PCL-3%PLA-NFs. The exposure to hydro-thermal stimulus resulted in maximum shape recovery, and the exposure to thermochemical exposure resulted in minimum shape recovery. Further, Fourier transform infrared (FTIR) spectroscopy analysis indicated that the absorbance spectrum of PCL is also affected by the concentration of PLA, as more uniform stretching and relaxation of carbonyl and C-C bond was observed in PCL-3%PLA-NFs.

The process is based on multi-scale decomposition (MSD) criteria in which filtering at multiple levels with focus detection is applied. The MSD tool used in this algorithm is Hilbert vibration decomposition (HVD), which decomposes an image into a set of instantaneous image amplitudes. These image amplitudes are passed through a mean filter to obtain filtered image amplitudes. Then, with the help of a fundamental difference operator, we get the high-frequency information, i.e., rough focus maps. These rough focus maps are further refined using guided filtering to obtain accurate focus maps. After this, weights are estimated on the choose max rule to generate the initial instantaneous fused image amplitudes. For spatial consistency verification, these fused image amplitudes are again filtered with the help of a guided filter. Then, the final weights are used to obtain the absolute instantaneous fused image amplitudes. These are recombined to generate the output fused image. In addition to this, we also apply a simplified image enhancement approach at the preliminary stage for better textures and contrast at the output.
