1An improved CRNN for Vietnamese Identity Card Information Recognition显示文摘This paper proposes an enhancement of an automatic text recognition system for extracting information from the front side of the Vietnamese citizen identity(CID)card.First,we apply Mask-RCNN to segment and align the CID card from the background.Next,we present two approaches to detect the CID card’s text lines using traditional image processing techniques compared to the EAST detector.Finally,we introduce a new end-to-end Convolutional Recurrent Neural Network(CRNN)model based on a combination of Connectionist Temporal Classification(CTC)and attention mechanism for Vietnamese text recognition by jointly train the CTC and attention objective functions together.The length of the CTC’s output label sequence is applied to the attention-based decoder prediction to make the final label sequence.This process helps to decrease irregular alignments and speed up the label sequence estimation during training and inference,instead of only relying on a data-driven attention-based encoder-decoder to estimate the label sequence in long sentences.We may directly learn the proposed model from a sequence of words without detailed annotations.We evaluate the proposed system using a real collected Vietnamese CID card dataset and find that our method provides a 4.28%in WER and outperforms the common techniques.Trinh Tan Dat Le Tran Anh Dang Nguyen Nhat Truong Pham Cung Le Thien Vu Vu Ngoc Thanh Sang Pham Thi Vuong Pham The Bao 2022Computer Systems Science & Engineering2022,40,2:0
2Temperature-mediated tribological characteristics of 40CrNiMoA steel and Inconel 718 alloy during sliding against Si_(3)N_(4) counterparts显示文摘A comparative evaluation of the friction and wear behaviors of 40CrNiMoA steel and Inconel 718 alloy sliding against Si_(3)N_(4) counterparts was conducted over a large temperature range from room temperature(RT)to 800℃.The temperature‐dependent tribological properties associated with the resulting chemical mitigation and structural adaptation of the solid sliding surface were clarified by surface/interface characterizations.The results revealed desirable performance in reducing friction and wear at elevated temperatures,which was associated with the resulting oxide composite filmʹs adaptive lubricating capability,whereas severe abrasive wear occurred at room/ambient temperatures.The oxidative‐abrasive differentials for the two alloys were further discussed by considering the combined effect of temperature and stressed‐shearing conditions.Liuyang BAI Shanhong WAN Gewen YI Yu SHAN Sang The PHAM Anh Kiet TIEU Yan LI Rendong WANG 2021Friction2021,9,5:0
