Matlab a hybrid multiview stereo algorithm for modeling urban scenes
0 likes32 views
Ecway Technologies provides software development and IEEE projects from offices located in multiple cities across India. Their hybrid multiview stereo algorithm allows for 3D modeling of urban scenes using a combination of meshes and geometric primitives. It first segments an initial mesh-based surface using a multilabel Markov Random Field model. It then simultaneously samples primitive and mesh components on the obtained partition using a Jump-Diffusion process. The algorithm refines the hybrid representation through an iterative procedure and provides more accurate reconstructions of complex urban structures compared to other multiview stereo meshing algorithms.

Mobile mapping systems can produce displaced point clouds from multiple scans of the same area. Point cloud and picture matching is required to register the data and produce an accurate combined point cloud. Structural features are then extracted from the point cloud, including road edges and lines, curbs, and other spatial elements like traffic signs and trees to create a 3D model. Terrestrial laser scanning can also efficiently digitize building facades by generating dense point clouds for further processing and engineering analysis.Buildings Recognition and Camera Localization Using Image Texture Description 
Buildings Recognition and Camera Localization Using Image Texture Description Wassim Suleiman

3D GIS model/2D image registration called much attention in the recent years because of its vast range of potential applications in real and virtual navigation. However, automatic registration remains until now a challenge. This paper presents a methodology for enhancing and complementing a GIS database of buildings with a descriptor of their texture by using information extracted from a reference images. This descriptor is used to locate any other image by searching similar texture in the image. Then the absolute position and orientation of the camera of the new image can be computed if the camera parameters (like focal length) are known. The paper proposes a technique that can be used for achieving the identification of the facade in the photograph, calibrated camera geolocation and discusses the quality of the results. 3D Visibility with Vector GIS Data

The visibility estimation has an important impact in many economical and aesthetic fields, a mixed environment which contains madman objects like buildings with relief sol make a challenge for the visibility calculation. This paper presents a new method to solve this problem based on vector GIS data. The use of vector data gives the possibility to calculate the intervisibility, viewshed for mixed environment. The new method could identify the obstacles (relief, buildings identification) which block the visibility for a 3D environment points from observator, the intervisibility impact of a specific building could be calculatedSimpleware and Abaqus

Ecway Technologies provides IEEE projects and software developments with offices across multiple cities in India. They specialize in image size invariant visual cryptography for general access structures subject to display quality constraints. Their approach uses column vectors to encrypt secret pixels rather than conventional VC methods. They developed a mathematical model and simulated annealing algorithm to find optimal column vectors for construction without pixel expansion or uncontrollable display quality issues in recovered images. Experimental results showed superior recovered image quality over previous studies.

This document describes a method for detecting vehicles in dense urban areas using aerial images. The method uses Histogram of Oriented Gradients (HoG) features and disparity maps from at least two subsequent images along with exterior orientation data, a digital elevation model, and a road database. Road segments from the database are projected onto the images using height data. Disparity maps are used to exclude elevated objects like buildings and vegetation. Region growing excludes homogeneous areas, and remaining areas are classified using HoG features. The approach was tested on images of Munich, achieving up to 70% accuracy in vehicle detection.

1. The document introduces an approach to enable query-adaptive ranking of images returned from image search based on hash codes.
2. It achieves this by first learning offline bitwise weights of hash codes for predefined semantic concept classes, and formulating the weight learning as a quadratic programming problem.
3. Query-adaptive weights are then computed online by evaluating the proximity between a query and semantic concept classes. This allows ordering returned images by a finer-grained weighted Hamming distance.Matlab estimating information from image colors an application to digital ca...

This document discusses estimating information from image colors and its application to digital cameras and natural scenes. It aims to derive estimators of the information available and retrieved from color values in images under different illuminations. The estimators were applied to simulations of images from five digital camera sensor sets and human eye cone photoreceptors using 50 hyperspectral natural scene images under daylight illuminants of varying color temperatures. Depending on the sensor set, the estimated mean information available across illuminations ranged from 15.5 to 18.0 bits, while the estimated mean information retrieved after processing ranged from 13.2 to 15.5 bits, representing about 85% of the available information.

This document summarizes a method for detecting buildings from satellite images. It begins with edge detection using Canny edge detection to extract lines from the image. These lines are then input into the Hough Transform to generate line segments. Hypothesis generation searches for rectangular structures using these line segments. Hypothesis verification is performed using color segmentation of the HSV image space and shadow detection. The final output is the extracted buildings from the urban areas of the satellite image.3-Phase Recognition Approach to Pseudo 3D Building Generation from 2D Floor P...

The document describes a method for intrinsic image decomposition of outdoor scenes from multiple views. Intrinsic images aim to separate an image into reflectance and illumination components to facilitate analysis or manipulation. Previous successful methods rely on user input or precise geometry. The proposed method estimates intrinsic images from multiple views of an outdoor scene without precise geometry, using a few manual calibration steps. A 3D point cloud is automatically reconstructed from multiview stereo, and is used to compute plausible sky and indirect illumination at each point, despite being sparse.

This document analyzes distance-based location management schemes (DBLMS) in wireless communication networks. A Markov chain mobility model is developed to describe a mobile terminal's movement in a 2D cellular structure. Classical renewal theory is used to analyze the expected number of paging area boundary crossings and cost of the distance-based location update method for two different call handling models. The analysis makes it possible to find the optimal distance threshold that minimizes the total cost of location management in a DBLMS.Analysis of distance based location management in wireless communication netw...

The method provides a compact model while preserving details: Irregular elements such as statues and ornaments are described by meshes, whereas regular structures such as columns and walls are described by primitives (planes, spheres, cylinders, cones, and tori). We adopt a two-step strategy consisting first in segmenting the initial meshbased surface using a multilabel Markov Random Field-based model and second in sampling primitive and mesh components simultaneously on the obtained partition by a Jump-Diffusion process. The quality of a reconstruction is measured by a multi-object energy model which takes into account both photo-consistency and semantic considerations (i.e., geometry and shape layout). The segmentation and sampling steps are embedded into an iterative refinement procedure which provides an increasingly accurate hybrid representation. Experimental results on complex urban structures and large scenes are presented and compared to state-of-the-art multiview stereo meshing algorithms.
