• Title: Registration Techniques for Deformable Objects
• Authors: Alireza Ahmadi
• Abstract summary: In general, the problem of non-rigid registration is about matching two different scans of a dynamic object taken at two different points in time. Since new parts of the model may come into view and other parts get occluded in between two scans, the region of overlap is a subset of both scans. This thesis is addressing is mapping deforming objects and localizing cameras in the environment at the same time.

• Abstract: In general, the problem of non-rigid registration is about matching two different scans of a dynamic object taken at two different points in time. These scans can undergo both rigid motions and non-rigid deformations. Since new parts of the model may come into view and other parts get occluded in between two scans, the region of overlap is a subset of both scans. In the most general setting, no prior template shape is given and no markers or explicit feature point correspondences are available. So, this case is a partial matching problem that takes into account the assumption that consequent scans undergo small deformations while having a significant amount of overlapping area [28]. The problem which this thesis is addressing is mapping deforming objects and localizing cameras in the environment at the same time.

• Accelerated Sub-Image Search For Variable-Size Patches Identification Based On Virtual Time Series Transformation And Segmentation [0.0]
  This paper addresses two tasks: (i) fixed-size objects such as hay bales to be identified in an aerial image for a given reference image of the object, and (ii) variable-size patches such as areas on fields requiring spot spraying or other handling are to be identified in an image for a given small-scale reference image. The exact number of similar sub-images is not known a priori.

• Neural Implicit Representation for Building Digital Twins of Unknown Articulated Objects [42.32306418464438]
  We address the problem of building digital twins of unknown articulated objects from two RGBD scans of the object at different articulation states. Our method first reconstructs object-level shape at each state, then recovers the underlying articulation model. It also handles more than one movable part and does not rely on any object shape or structure priors.

  We formulate the task of temporal action detection in a novel perspective of semantic segmentation. Owing to the 1-dimensional property of TAD, we are able to convert the coarse-grained detection annotations to fine-grained semantic segmentation annotations for free. We propose an end-to-end framework SegTAD composed of a 1D semantic segmentation network (1D-SSN) and a proposal detection network (PDN)

• Reference-based Defect Detection Network [57.89399576743665]
  The first issue is the texture shift which means a trained defect detector model will be easily affected by unseen texture. The second issue is partial visual confusion which indicates that a partial defect box is visually similar with a complete box. We propose a Reference-based Defect Detection Network (RDDN) to tackle these two problems.

• Object-centered image stitching [15.850092529468004]
  Image stitching is typically decomposed into three phases: registration, seam finding, and blending. Here, we observe that the most problematic failures of this approach occur when objects are cropped, omitted, or duplicated. We take an object-centered approach to the problem, leveraging recent advances in object detection.
