In this paper we present an algorithm for depth estimation from a monocular video sequence containing moving and deformable objects. The method is based on a coded aperture system (i.e., a conventional camera with a mask placed on the main lens) and it takes a coded video as input to provide a sequence of dense depth maps as output. To deal with nonrigid deformations, our work builds on the sta...

Consider a definition of depth of a logic as the supremum of ordinal types of wellordered descending chains. This extends the usual definition of codimension to infinite depths. Logics may either have no depth, or have countable depth in case a maximal well-ordered chain exists, or be of depth !1. We shall exhibit logics of all three types. We show in particular that many well-known systems, am...

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, ...

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 ...

The problem of bottom hole effusion is an important reason for the reduction and even shutdown natural gas wells. Downward velocity string drainage recovery process, which can improve flow rate discharge more liquid from wellhead. However, depth timing a technical that has been difficult to solve by field engineers. To this problem, paper designs method select in case highly deviated wells appl...
