Luanzheng Guo/Anzheng Guolu
I am a fourth-year Ph.D. student in Computer Science at UC Merced where I am advised by Professor Dong Li. Currently my research interests lie in resilience problems on large-scale parallel systems. Previously I was working on Computer Vision topics with machine learning methods with Professor Jun Chu and Professor Chuhong Pan and Professor Shiming Xiang.

Projects
“Building the Detailed Dynamic Dependency Graph (DDDG) for Applications” Advisor: Prof. Dong Li, Ignacio Laguna. (On-going)
view detailsConstructing the DDDG graph for an entire application instead of only one function, one module, or one loop, in which the values for registers and memories, and the dynamic control flows are visible.
“Identification of the fault resilience logic for machine learning like algorithms on large scale system”, Mentor: Ignacio Laguna, Prof. Dong Li. (On-going)
view detailsThe target is to recognize the inner logic of some algorithms that why they can tolerate underneath faults of large scale system derived from device worn, cosmos radiation like neutrons, and temperature. And then
coming up with a methodology to automatically detect the fault resilience logic of the algorithms.
“Analysis on application-level fault tolerance on large scale system”, advisor: Prof. Dong Li. (On-going)
view detailssoft errors (transient faults) due to reasons like cosmic rays are already making an impact in industry, and so many internet companies suffer from it. Generally, the damage brought by soft errors can be rolled
back with great overhead, so what should we do to solve the problem? One feasible way is to protect the data and make the program more robust. Our goal is to propose a metric to evaluate the vulnerability of
data within specific program, which will be used as the criterion to estimate the degree of protection on each data.
“Target Tracking Based on Context-aware and Sparse Representation”, advisor: Prof. Lingfeng Wang.
view detailsprior research on classifying human beings on depth information.
1) read papers related to the specific research area and make a conclusion on existing methods; 2) try to propose a novel model to solve the problem from a new prospect.
“Gesture Recognition based on 2D and 3D Information” (course project)
view detailsIdentifying different gestures based on their 2D and 3D information.
1) fetching the 2D and 3D information of gestures with Kinect; 2) extracting the palm area out of the background based on depth discrimination; 3) smoothing the 3D mesh and extract the outline of gestures; 4) calculating
the convex-hull for gestures based on their outline; 5) using an Adaboost classifier to recognize different gestures.
“Urban building modeling by integrating 2D and 3D information”, advisor: Prof. Chunhong Pan.
view detailsReasoning the framework of Indoor Scenes from a single image.
1) conducted some researches into the most essential part of indoor scene recognition, known as indoor frame recovery; 2) address difficulties such as illumination variations, weak boundaries and partial occlusions;
3) proposed an approach based on line segment refinement and voting; 4) refined detected line segments by revising, connecting, and adding operations; 5) utilized an iterative voting mechanism to select from
refined line segments, where a cross ratio constraint is enforced to build the frame.
“Theories of Linear Reconstruction Natural Scenes Based on Spatial Invariants”, advisor: Prof. Jun Chu.
view detailscalibrating the panorama cameras stably under complex scenes. (Coding with Matlab)
1) considered approaches based on chessboard panel; 2) proposed two algorithms of chessboard corner detectors based on a round template and a circular template, respectively, under image physical coordinate; 3)
the physical coordinates allowed detected chessboard corners to reach the sub-pixel level in only one step; 4) experiment results prove that our algorithms can achieve better results in complex scenes.
“Key techniques for modeling the lunar surface for exploration and patrol”, advisor: Prof. Ouyang Ziyuan.
view detailsfinding a stable and efficient approach to calibrate the cameras fixed on the mobile robot. (Coding with C++)
1) there are four cameras, two panorama cameras and two navigation cameras. For the navigation cameras, I fixed their focal lengths. But for the panorama camera, the focal length could not be fixed; 2) discovered
a problem that the calibration parameters of the panorama cameras could vary, as the robot is moving; 3) to address that, each time before taking pictures in 360 degrees, I stopped the robot and calibrated the
panorama cameras with a fixed chessboard panel on the robot.
