In this paper, we use a advanced method called Faster R-CNN to detect traffic signs. This new method represents the highest level in object recognition, which don't need to extract image feature manually anymore and can segment image to get candidate region proposals automatically. Our experiment is based on a traffic sign detection competition in 2016 by CCF and UISEE company. The mAP(mean average...
Over the past years, automatic traffic accident detection (ATAD) based on video has become one of the most promising applications in intelligent transportation and is playing a more and more important role in ensuring travel safety. This paper proposes a classifier-based supervised method by viewing the last seconds before motor vehicle collisions as the detection target. In our method, we devise...
This paper mainly proposes a deep learning method-Stacked Denoising Auto Encoder (SDAE) to solve the problems of automatic feature extraction and dimension reduction in Braille recognition. In the construction of a network with deep architecture, a feature extractor was trained with unsupervised greedy layer-wise training algorithm to initialize the weights for extracting features from Braille images,...
A robotic scrub nurse (RSN) designed for safe human-robot collaboration in the operating room (OR) is presented. The RSN assists the surgical staff in the OR by delivering instruments to the surgeon and operates through a multimodal interface allowing instruments to be requested through verbal commands or touchless gestures. A machine vision algorithm was designed to recognize the hand gestures performed...
According to the current circumstances, the cultivating and training of the newest armored equipments maintenance support personnel is difficult to meet army's demand all the time, and can't meet the needs of equipments development either, we researched the maintenance training simulation system which is basic to half-practicality and virtual reality technology in chief. We made the overall design...
As the goal of development, teacher professionalization is not only an effective way to improve individual professional standards of teachers and qualities of education, but also a certain requirement of development of modern education. In china, teacher professional development is not ripe, needs to continually deepen and advance. The basic research starting point of teacher professional development...
In this paper, we focus on the human accumulation problems in China; In order to realize the rapid development of China's economic we must know the problems exist in China's human capital accumulation. On the basis of previous theories presented in Section 2, the human capital accumulation's effect to China's economic growth and its existing problems are discussed in Section 3 and Section 4. By using...
Disassembly is one of the important processes of complex equipments maintenance. On the basis of analyzing the maintenance characteristic of complexity equipments, a method to generate disassembly sequence is presented. Using the knowledge of graph theory, the method realizes to generate automatically the optimal disassembly sequence through establishing the constraint matrix. And the method is applied...
