In our contribution, we improve image segmentation by integrating depth information from multi-view analysis. We assume the object surface in each region can be represented by a low order polynomial, and estimate the best fitting parameters of a plane using those points of the point cloud, which are mapped to the specific region. We can merge adjacent image regions, which cannot be distinguishe...

Full-waveform lidar system records the received signals continuously for analysis. As it provides more information than the conventional pulsed lidar, the waveform lidar plays an important role in land cover classification as well as object reconstruction. The objective of this research is to analyze the features of grouped full-waveform lidar point clouds. The two major works are segmentation ...

| In this paper some new results for multidimensional m-band bi-orthogonal lter banks are presented. In the rst part of the paper we introduce the ladder structure as a method for the design and implementation of aforementioned lter banks. The theory of ladders and the relation to lter banks is presented. The second part of the paper focuses upon linear phase conditions for bi-orthogonal lter b...

In this paper we would like to present our application for editing and visualizing huge point clouds. We also show how we used our application to build a model of the Domitilla Catacomb in Rome, which is the largest catacomb in Rome. It is an Early-Christian necropolis spanning 15 km of subterranean galleries. The catacomb contains tombs and community burials, where some of the tombs are painte...

Bingheng Wang Dept. of Computer Science Florida Institute of Technology Melbourne FL 32904 [email protected] ABSTRACT Given a list of elements, we rearrange the list with ascending or descending order. So far the existing approaches involve Bubble Sort, Insertion Sort, Selection Sort ( respectively in worst case) performing slow. Now we introduce a new algorithm Merge Sort to solve the problem ...

In this paper we analyze the implementation of socially optimal mergers when the regulator is not informed about all parameters that determine social and private gains from potential mergers. We show that implementation requires a certain degree of agreement between social and private incentives. The most important example where this congruence is present is when the uncertainty refers to cost ...

Merging two sorted arrays is a prominent building block for sorting and other functions. Its efficient parallelization requires balancing the load among compute cores, minimizing the extra work brought about by parallelization, and minimizing inter-thread synchronization requirements. Due to the extremely low compute to memoryaccess ratio, it is also critically important to efficiently utilize ...
