Many consumer digital cameras support dual shooting mode of both low-resolution (LR) video and high-resolution (HR) image. By periodically switching between the video and image modes, this type of cameras make it possible to super-resolve the LR video with the assistance of neighboring HR still images. We propose a model-based video super-resolution (VSR) technique for the above dual-mode cameras...
In this paper we propose a new approach for disocclusion removal in depth image-based rendering (DIBR) for 3D-TV. The new approach, Hierarchical Hole-Filling (HHF), eliminates the need for any preprocessing of the depth map. HHF uses a pyramid like approach to estimate the hole pixels from lower resolution estimates of the 3D wrapped image. The lower resolution estimates involves a pseudo zero canceling...
We envision a conference room of the future where depth sensing systems are able to capture the 3D position and pose of users, and enable users to interact with digital media and contents being shown on immersive displays. The key technical barrier is that current depth sensing systems are noisy, inaccurate, and unreliable. It is well understood that passive stereo fails in non-textured, featureless...
With the increase of the number of the blind, demand for visual prosthesis is increasing. Text reading is one of the most important visual functions to the blind. Therefore human trials and simulations of prosthetic vision have already been carried out for testing an improved system or studying rehabilitation of people who implant prosthesis. But although forms of electrode arrays used in those studies...
This work aims at investigating the influence of luminance information and environment illumination on skin classification. We explore Bayesian approaches to perform automatic classification of human skin pixels on digital images, using color features as input. Two probabilistic skin color models were built on different color spaces (RGB, normalized RG, HSI, HS, YCbCr and CbCr) and tested in a task...
