The large interest in autonomous vehicles is a significant driver for computer vision research. Current deep learning approaches are capable of impressive feats, like dense full frame depth prediction from a single image. While impressive results have been achieved, it is not yet clear if they are sufficient for autonomous driving. The problem remains that existing evaluation benchmarks and metric...Show More
We propose a method for depth estimation from light field data, based on a fully convolutional neural network architecture. Our goal is to design a pipeline which achieves highly accurate results for small-and wide-baseline light fields. Since light field training data is scarce, all learning-based approaches use a small receptive field and operate on small disparity ranges. In order to work with ...Show More
We address the problem of depth estimation from light-field images. Our main contribution is a new way to handle occlusions which improves general accuracy and quality of object borders. In contrast to all prior work we work with a model which directly incorporates both depth and occlusion, using a local optimization scheme based on the PatchMatch algorithm. The key benefit of this joint approach ...Show More
Convolutional neural networks, or CNNs, raised the bar for most computer vision problems and have an increasing impact in remote sensing. However, since they usually contain multiple pooling layers, detection of exact borders of small objects at their original resolution remains yet a challenging topic. Additionally, efforts are being made to reduce the amount of training data. In this paper, we i...Show More
Specular highlights provide information about the shape of an object. Its characteristics are mostly unwanted in computer vision due to violation of the Lambertian assumption, which most algorithms require. Instead of neglecting this ubiquitous phenomenon we harvest it to extract surface normals with very high accuracy. Compared to photometric stereo our method works with multiple views and a fixe...Show More
This paper presents the results of the depth estimation challenge for dense light fields, which took place at the second workshop on Light Fields for Computer Vision (LF4CV) in conjunction with CVPR 2017. The challenge consisted of submission to a recent benchmark [7], which allows a thorough performance analysis. While individual results are readily available on the benchmark web page http://www....Show More
Detection of vehicles in remote sensing data represents a captivating and challenging task that has been studied during many years. The state-of-the-art detection tools can be subdivided into implicit and explicit methods; the latter ones provide detection results by means of some explicitly characterizing features. Mostly, these methods rely on optical aerial images in which vehicles appear disto...Show More
Context-based modeling of 3D urban terrain has become increasingly popular in the last two decades. Typically, orthophotos are used for texturing ground. In order to increase locational awareness, it is useful to eliminate from the orthophotos those object instances which frequently appear and disappear in the terrain. Vehicles are good examples of such instances. Assuming that vehicles were detec...Show More
Different methods for the detection for hydrocarbons in aerial hyperspectral images are analyzed in this study. The scope is to find a practical method for airborne oil spill mapping on land. Examined are Hydrocarbon index and Hydrocarbon detection index. As well as spectral reidentification algorithms, like Spectral angle mapper, in comparison to the indices. The influence of different ground cov...Show More
This paper suggests a method for automatic in-flight boresight calibration of pushbroom scanner images, using an on-line system with broadband data downlink and near realtime georeferencing of the pushbroom image data. Georeferencing accuracy may decrease during long image acquisition flights due to instable atmospheric conditions, which may lead to geometric changes in the flight platform. Orthor...Show More
Nonlinear effects in hyperspectral data complicate classification and other data analysis procedures. Transforming the data onto manifolds can help to improve the results while simultaneously reducing the dimensionality due to the high correlation among the spectral bands. Methods like ISOMAP or Locally Linear Embedding are not ideal when the data is degraded by noise. In this paper, a method is i...Show More
In the last few years, unmixing of hyperspectral data has become of major importance. The high spectral resolution results in a loss of spatial resolution. Thus, spectra of edges and small objects are composed of mixtures of their neighboring materials. Due to the fact that supervised unmixing is impossible for extensive data sets, the unsupervised Nonnegative Matrix Factorization (NMF) is used to...Show More
