A new stereoscopic image quality assessment database rendered using the 2D-image-plus-depth source, called MCL-3D, is described and the performance benchmarking of several known 2D and 3D image quality metrics using the MCL-3D database is presented in this work. Nine image-plus-depth sources are first selected, and a depth image-based rendering (DIBR) technique is used to render stereoscopic im...

A quality scalable extension design is proposed for the upcoming 3D video on the emerging standard for High Efficiency Video Coding (HEVC). A novel interlayer simplified depth coding (SDC) prediction tool is added to reduce the amount of bits for depth maps representation by exploiting the correlation between coding layers. To further improve the coding performance, the coded prediction quadtre...

As an object approaches the eye, its retinal image size grows larger and its surface texture appears to grow coarser. We compare these two visual correlates of motion in their effectiveness as stimuli for motion in depth. In some experiments texture and object size both expanded or both contracted; in other experiments the two stimuli were pitted against each other. When texture and size change...

Global shape judgements were employed to examine the combination of stereopsis and shape-from-texture in the determination of three-dimensional shape. Adding textural variations to stereograms increased perceived depth. Thus, texture was not simply vetoed by the strong stereo cue. In experiments where the depth specified by texture was incongruent with that specified by stereo, the data were we...

hand shape, etc. Two dimensional (2D) palmprint recognition [1-4, 16-18] has been widely studied in the past decade and it has been proven that palmprint is a unique biometric identifier. 2D palmprint systems have merits of high accuracy and user friendliness, etc. Nonetheless, 2D palmprint can be easily counterfeited and much three dimensional (3D) palm structural information is lost. Inspired...

We propose a method for estimating face depth maps from color face images. The method is based on Canonical Correlation Analysis (CCA) which exploits the correlation between face color texture and surface depth. The results of experiments conducted on a database of 218 3D scans with corresponding color images show that only a small number of canonical factors are needed to describe the function...

Projected texture based 3D sensing modalities are being increasingly used for a variety of 3D computer vision applications. However, these sensing modalities, exemplified by the Microsoft Kinect Sensor, suffer from severe drawbacks that hamper the quality of the range estimate output from the sensor. It is well known that the quality of reconstruction of the 3D projected texture for range estim...

A fundamental problem in depth from defocus is the measurement of relative defocus between images. We propose a class of broadband operators tha t , when used together, provide invariance to scene texture and produce accurate and dense depth maps. Since the operators are broadband, a small number of them are sufficient for depth estimation of scenes with complex textural properties. Experiments...
