  1. Vector Distance Transform Maps for Autonomous Mobile Robot Navigation

    Arukgoda, Janindu Sithumini2020

    … environments can be represented using the vector distance transform for mobile robot localization, and show that it is a superior representation compared to alternatives such as occupancy grid maps and other distance transform variants such as the unsigned distance transform and the signed …

  2. Localizing, modeling, and drifting an autonomous RACECAR

    Walsh, Corey HMassachusetts Institute of Technology2018

    … grid maps, called the Compressed Directional Distance Transform (CDDT). Here, I will discuss the theory and characteristics of the CDDT algorithm, which has been implemented in RangeLibc, my open-source software library.

  3. Algorithms for design and interrogation of functionally graded material solids

    Liu, Hongye, 1970-Massachusetts Institute of Technology2000

    … based 3D model, the design tool based on the distance function from the surface of the part and the design tool allowing the user to design within a .STL file require enhanced efficiency and so does the interrogation of the part. The approach for improving efficiency includes preprocessing the …

  4. Comparing visual features for morphing based recognition

    Wu, Jia JaneMassachusetts Institute of Technology2005

    … morph. A scoring metric, using both LMEDS and distance transform, is used to classify test images based on a nearest neighbor algorithm. We perform the experiments on the Caltech 101 dataset [5]. To ease computation, for each test image, a shortlist is created containing 10 of the most likely …

  5. Feature-based design of solids with local composition control

    Liu, Hongye, 1970-Massachusetts Institute of Technology2004

    … include functions parametrized with respect to distance or distances to user-defined geometric features; and functions that use Laplace's equation to blend smoothly various boundary conditions including values and gradients of the material composition on the boundaries. The Euclidean digital …

  6. Digital twin volume registration for Voxel-based closed-loop machining systems

    Collins, James S.Georgia Institute of Technology2018

    … Through the implementation of a Euclidean distance transform and variance calculation, an intensity-based similarity metric is demonstrated over a discrete voxel domain driven by a metaheuristic registration algorithm. Simulation tests conducted over a uniform grid structure show that the …

  7. Real-Time Forward Urban Environment Perception for an Autonomous Ground Vehicle Using Computer Vision and LIDAR

    Greco, Christopher Richard2008

    … lane of the vehicle is detected using a minimum distance transform and tracked between frames. The stop lines and obstacles are detected from the non-road information in the mask. Stop lines are detected using a variation of vertical profiling, and obstacles are detected using shape descriptors. …

    Wu, Yi-Ta

    … method is first presented to obtaining Euclidean distance transformation (EDT) in just two scans of image. The shortest path can be extracted based on distance maps by tracking minimum values. In order to record the motion path, a new chain-code representation is developed to allow forward and …
