A depth enhancement strategy for kinect depth image
MIPPR 2017: Pattern Recognition and Computer Vision, 2018Kinect is a motion sensing input device which is widely used in computer vision and other related fields. However, there are many inaccurate depth data in Kinect depth images even Kinect v2. In this paper, an algorithm is proposed to enhance Kinect v2 depth images. According to the principle of its depth measuring, the foreground and the background are

Image-based localization with depth-enhanced image map
2003 IEEE International Conference on Robotics and Automation (Cat. No.03CH37422), 2004In this paper, we present an image-based robot incremental localization algorithm which uses a panoramic image-based map enhanced with depth from a laser range finder. The image-based map (model) contains both intensity information as well as sparse 3D geometric features. By assuming motion continuity, a robot can use the depth information in the image-

Learning Dynamic Guidance for Depth Image Enhancement
2017 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2017The depth images acquired by consumer depth sensors (e.g., Kinect and ToF) usually are of low resolution and insufficient quality. One natural solution is to incorporate with high resolution RGB camera for exploiting their statistical correlation.

Localized image enhancement using depth map
2014 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT), 2014The main objective of this paper is to propose a method for localized image enhancement. This method can be highly beneficial in medical purposes, like Laminography, or in enhancing images captured under non-uniform illumination. Along with a depth map, a spatial queue-based data structure is used to properly locate the area to be enhanced in the ...

Pattern image enhancement by extended depth of field
Microelectronics Reliability, 2014Abstract Most optical defect localization techniques such as dynamic laser stimulation or photon emission microscopy require a pattern image of the device to be taken. The main purpose is for device navigation, but it also enables the analyst to identify the location of the monitored activity by superimposing it onto the pattern image.

Depth Image Enhancement Algorithm Based on RGB Image Fusion
2018 11th International Symposium on Computational Intelligence and Design (ISCID), 2018Considering the problem that large amount of structural defects in the depth image captured by Kinect2 decreased the accuracy of object detection and recognition. This paper proposed a depth image enhancement algorithm that fused RGB image information. Firstly, a synchronized RGB image was introduced and aligned with the depth image. Secondly, based on

Enhancing perceived depth in images via artistic matting
Proceedings of the 1st Symposium on Applied perception in graphics and visualization, 2004We present a simple tutorial for the addition of artistic mattes to digital images for the purpose of enhancing the three-dimensional effect of the image. We show that artistic mattes add visual cues to an image enhancing the sense of depth in the image.

Robust enhancement of depth images from Kinect sensor
2015 IEEE Virtual Reality (VR), 2015We propose a new method to fill missing or invalid values in depth images generated from the Kinect depth sensor. To fill the missing depth values, we use a robust least median of squares (LMedS) approach. We apply our method for telepresence environments, where Kinects are used very often for reconstructing the captured scene in 3D.

Resolution enhancement in single depth map and aligned image
2016 IEEE Winter Conference on Applications of Computer Vision (WACV), 2016Depth resolution enhancement aims to recover a high quality depth map from one or multiple low-resolution depth input(s) with missing pixels. While a registered high-resolution intensity image is often utilized to assist, little attention has been paid to the circumstances when there is only one pair of low-resolution depth map and aligned intensity ...

Depth Image Enhancement and Detection on NSCT and Fractional Differential
Wireless Personal Communications, 2018For enhancing the low contrast and detecting the noise in depth image from Kinect sensor, the Non-Subsampled Contourlet Transform (NSCT) and non-linear fractional differential are studied in this paper. Firstly, on the basis of the NSCT’s advantages, the depth image is decomposed into low frequency and high frequency.
