Fast Depth Map Upsampling using Edge Information
نویسنده
چکیده
In this paper, we propose a new depth map upsampling method to increase the depth image resolution using edge information. Although the joint bilateral upsampling (JBU) method expands the resolution of the depth map using two weighting functions, the complexity of JBU is relatively high. In the proposed upsampling method, we reduce the complexity of depth map upsmapling operation using a color weighting function chosen by the guide information. We use the modified mean absolute difference value with the Gaussian weighting function to obtain the guide information. Experimental results show that the proposed upsampler outperforms JBU in terms of the computational complexity. Keywords—joint bilateral filter; depth map upsampling

Efficient Depth Map Upsampling Method Using Standard Deviation
In this paper, we present an adaptive multi-lateral filtering method to increase depth map resolution. Joint bilateral upsampling (JBU) increases the resolution of a depth image considering the photometric property of corresponding high-resolution color image. The JBU uses both a spatial weighting function and a color weighting function evaluated on the data values. However, JBU causes a textur...
متن کاملEdge-preserving down/upsampling for depth map compression in high- efficiency video coding
An efficient down/upsampling method to compress a depth map efficiently within the high-efficiency video coding (HEVC) framework is presented. A different edge-preserving depth upsampling method is proposed by using both the texture and depth information. We take into account the edge similarity between depth maps and their corresponding texture images as well as the structural similarity among...
متن کاملDepth Map Super-Resolution by Deep Multi-Scale Guidance
Depth boundaries often lose sharpness when upsampling from low-resolution (LR) depth maps especially at large upscaling factors. We present a new method to address the problem of depth map super resolution in which a high-resolution (HR) depth map is inferred from a LR depth map and an additional HR intensity image of the same scene. We propose a Multi-Scale Guided convolutional network (MSG-Ne...
متن کاملTemporal Upsampling of Depth Maps Using a Hybrid Camera
In recent years consumer-level depth sensors have been adopted in various applications. However, they often produce depth maps at a not very fast frame rate (around 30 frames per second), preventing them from being used for applications like digitizing human performance involving fast motion. On the other hand there are available low-cost faster-rate video cameras. This motivates us to develop ...
متن کاملRobust High Quality Image Guided Depth Upsampling
Time-of-Flight (ToF) depth sensing camera is able to obtain depth maps at a high frame rate. However, its low resolution and sensitivity to the noise are always a concern. A popular solution is upsampling the obtained noisy low resolution depth map with the guidance of the companion high resolution color image. However, due to the constrains in the existing upsampling models, the high resolutio...
