Enhancing view synthesis with image and depth map upsampling
2017 International Conference on Systems, Signals and Image Processing (IWSSIP), 2017In the paper we present a method for increasing the quality of views synthesized with typical Depth-Image-Based Rendering (DIBR) view synthesis algorithms. In the proposed idea the resolution of input real views and corresponding depth maps is doubled before the view synthesis.

Depth Enhancement and Optimization for Stereo Images Based on JNDD
2018 11th International Congress on Image and Signal Processing, BioMedical Engineering and Informatics (CISP-BMEI), 2018With rapid progress of three-dimensional television and 3D film industry, stereoscopic technology has become an increasingly important aspect of image technology in recent years. Therefore, in this paper, processing of stereo images is mainly focused on. Based on this new Just Noticeable Depth Difference (JNDD) model, a Modified Local Depth Enhancement

A CNN cascade for quality enhancement of compressed depth images
2017 IEEE Visual Communications and Image Processing (VCIP), 2017Transmitting depth images along with the corresponding textures enables a wide range of receiver-side 3D applications. Since each pixel on the depth images represents a corresponding 3D scene geometric information, when compressed during transmission the compression artifacts will lead to severe geometry distortions and visual perceptual degradation ...

Time-of-flight image enhancement for depth map generation
2016 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA), 2016Time-of-Flight (ToF) cameras are easily accessible in this era. They capture real distances of objects in a controlled environment. Yet, the ToF image may include disconnected boundaries between objects. In addition, certain objects are not capable of reflecting the infrared ray such as black hair. Such problems are caused by the physics of ToF.

Enhancing the Depth Resolution of Contactless Electrical Conductivity Imaging
Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006Contactless electrical conductivity imaging (CECI) collects magnetic field measurements of the induced currents from a biological subject. Because magnetic induction strength is highly dependent on the distance between the source and the measurements, information about the deeper conductivity variations are highly vulnerable to measurement noise.

Combining color and depth for enhanced image segmentation and retargeting
The Visual Computer, 2011As depth cameras become more popular, pixel depth information becomes easier to obtain. This information can clearly enhance many image processing applications. However, combining depth and color information is not straightforward as these two signals can have different noise characteristics, differences in resolution, and their boundaries do not ...

Depth image enhancement using perceptual texture priors
SPIE Proceedings, 2015A depth camera is widely used in various applications because it provides a depth image of the scene in real time. However, due to the limited power consumption, the depth camera presents severe noises, incapable of providing the high quality 3D data. Although the smoothness prior is often employed to subside the depth noise, it discards the geometric ...

Image Contrast Enhancement Using Color and Depth Histograms
IEEE Signal Processing Letters, 2014In this letter, we propose a new global contrast enhancement algorithm using the histograms of color and depth images. On the basis of the histogram-modification framework, the color and depth image histograms are first partitioned into sub-intervals using the Gaussian mixture model. The positions partitioning the color histogram are then adjusted such
