In this paper, we propose a method to extract depth from motion, texture and intensity. We first analyze the depth map to extract a set of depth cues. Then, based on these depth cues, we process the colored reference video, using texture, motion, luminance and chrominance content, to extract the depth map. The processing of each channel in the Y CRCB−color space is conducted separately. We test...

With the introduction of the original Radeon the general rendering performance landscape changed significantly due to the revolutionary technology that is HyperZ. Today this technology has been upgraded, fine-tuned and improved in several generations and is now a general commodity that everyone expects to have. Yet it is sometimes not well understood or taken proper advantage of. Developing 3D ...

Orifice-weir structures are being used to reduce peak drainage rates and to store water during the growing season in poorly drained pine plantations. Earlier studies have demonstrated their effectiveness in reducing drainage outflows while conserving water during the growing season. This study reports on criteria and preliminary guidelines for designing such structures. The guidelines were deve...

[1] Wave-generated shear stresses are the main mechanism responsible for sediment erosion on tidal flats and regulate both sediment concentrations in the water column and, together with tidal currents, sediment export to salt marshes and to the ocean. We present herein a simple method to estimate sediment erosion potential in shallow tidal basins caused by wind wave events. The method determine...

Anionic reactive dyes used to dye nylon suffer from failures due to the poor efficiency caused by low degree of exhaustion and fixation. From the previous work , the dyeing efficiency of Procion Rubine XL on modified nylon was particularly week and hence offers the widest scope for an in depth investigation in to variables that effect the dyeing process. The variables dyeing studies for this pr...

Recently, a variety of stereoscopic contents have been provided to academic and industrial fields for broadcasting, movies and mobile materials. However, few works have been interested in the adjustment of 3D contents for diverse displays. For instance, movie contents suited to large screen frequently do not deliver the same 3D perception to small-size screen such as mobile phone, tabular PCs, ...

This study investigated the vault settlement characteristics of an unsymmetrically loaded tunnel which was excavated by annular excavation via core rock support method. Response surface methodology (RSM) was employed to design the experiments, evaluate the results with the purpose of optimizing the value of design parameters for reducing the vault settlement. The parameters such as horizontal d...

The relationship between color and perceived depth for realistic, colored objects with varying shading was explored. Background: Studies have shown that warm-colored stimuli tend to appear nearer in depth than cool-colored stimuli. The majority of these studies asked human observers to view physically equidistant, colored stimuli and compare them for relative depth. However, in most cases, the ...
