Real-Time Motion Artifact Compensation for PMD-ToF Images
Time-of-Flight (ToF) cameras gained a lot of scientific attention and became a vivid field of research in the last years. A still remaining problem of ToF cameras are motion artifacts in dynamic scenes. This paper presents a new preprocessing method for a fast motion artifact compensation. We introduce a flow like algorithm that supports motion estimation, search field reduction and motion fiel...
متن کاملReal-time Planar Segmentation of Depth Images
Handling depth images as a point cloud in a 3D data framework and performing planar segmentation in real-time requires heavy computation and it is a major challenge. Available planar-segmentation algorithms are mostly based on surface normals and/or curvatures, and consequently, do not provide real-time performance. In this abstract paper, we introduce a real-time planar-segmentation method for...
متن کاملFrequency Domain TOF: Encoding Object Depth in Modulation Frequency
Time of flight cameras may emerge as the 3-D sensor of choice. Today, time of flight sensors use phase-based sampling, where the phase delay between emitted and received, high-frequency signals encodes distance. In this paper, we present a new time of flight architecture that relies only on frequency—we refer to this technique as frequencydomain time of flight (FD-TOF). Inspired by optical cohe...
متن کاملPlane Fitting and Depth Variance Based Upsampling for Noisy Depth Map from 3D-ToF Cameras in Real-time
Recent advances of ToF depth sensor devices enables us to easily retrieve scene depth data with high frame rates. However, the resolution of the depth map captured from these devices is much lower than that of color images and the depth data suffers from the optical noise effects. In this paper, we propose an efficient algorithm that upsamples depth map captured by ToF depth cameras and reduces...
متن کاملTime-Frequency Analysis of EEG Signal processing for Artifact Detection
EEG is widely used to record the electrical activity of the brain for detecting various kinds of diseases and disorders of the human brain. EEG signals are contaminated with several unwanted artifacts during EEG recording and these artifacts make the analysis of EEG signal difficult by hiding some valuable information. Time-frequency representation of electroencephalogram (EEG) signal provides ...
