Shape detection in point clouds
free download

ABSTRACT In this work we present an automatic algorithm to detect basic shapes in unorganized point clouds. The algorithm decomposes the point cloud into a concise, hybrid structure of inherent shapes and a set of remaining points. Each detected shape serves as 

Example based non-rigid shape detection

Since it is hard to handcraft the prior knowledge in a shape detection framework, machine learning methods are preferred to exploit the expert annotation of the target shape in a database. In the previous approaches [1, 2], an optimal similarity transformation is 

Geometric shape detection with soundview
free download

ABSTRACT We present the results of user studies that were performed on sighted people to test their ability to detect simple shapes with SoundView. SoundView is an experimental vision substitution system for the blind. Visual images are mapped onto a virtual surface

If a robot shall learn from visual data the task is greatly simplified if visual data isAbstracted from pixel data into basic shapes or Gestalts. This paper introduces a method of processing images toABSTRACT basic features into higher level Gestalts. Grouping is formulated as 

Continuation schemes for shape detection in inverse acoustic scattering problems
free download

ABSTRACT We discuss simple numerical schemes, termed continuation schemes, for detecting the location and shape of a scatterer embedded in a host acoustic medium, when considering scant measurements of the scattered acoustic pressure in the vicinity (near-or 

Fruit shape detection by level set
free download

ABSTRACT A novel approach for fruit shape detection in RGB space was proposed, which was based on fast level set and Chan-Vese model named as Modified Chan-Vese model (MCV). This new algorithm is fast and suitable for fruit sorting because it does not need re- 

An MRF model based algorithm of triangular shape object detection in color images

 Roth et al [3] proved that the shape detection problem can be formulated in term of an optimization problem, so the genetic algorithm is proposed to solve this prob- lem [4]. However it is only applied to binary image and its optimization process is Page 2. 

Advancement in automatic monitoring and detection of archaeological sites using a hybrid process of Remote Sensing, GIS techniques and a shape detection 
free download

ABSTRACT The method developed in the frame of the project HORUS (Heritage Observation and Retrieval Under Sand funded by European Space Agency) for the automatic monitoring and identification of lost or undiscovered archaeological sites in Egypt has been improved 

Combining plane estimation with shape detection for holistic scene understanding
free download

Structural scene understanding is an interconnected process wherein modules for object detection and supporting structure detection need to co-operate in order to extract cross- correlated information, thereby utilizing the maximum possible information rendered by
