Algorithm Engineer- I received my B.E in Mechanical Engineering from Yangtze University, China in 2013, and M.Sc. in Mechanical Engineering from Guangxi University of Science and Technology, China in 2016. After graduation, I have been working in Shenzhen, a city in the south of China. I mainly engaged in working with algorithm development,and my main interests are image processing algorithms,computer vision,machine learning,automated driving simulation,3D vision algorithms,deep learning,C/C++ code generation,graph theory,human activity recognition,scientific graphics/computing, etc. Additionally,I usually use some git,cmake,docker,linux(ubuntu),shell,RoadRunner and Matlab/Simulink, Python, C/C++ language tools. Note:13+ years of continuous experience using MATLAB.
