Abstract. Differential methods belong to the most widely used techniques for optic flow computation in image sequences. They can be classified into local methods such as the Lucas–Kanade technique or Bigün’s structure tensor method, and into global methods such as the Horn/Schunck approach and its

t is very rewarding for us to receive a serious commentary on "When is Statistical Significance not Significant?". We are pleased with Silva and Guarnieri's (2014) remarks and we believe that they generally agree with us. However, their review makes it clear that some points were

structure-from-motion, then recon-structs object shapes by optimizing over visual hull propos-als guided by loose within-class shape similarity assump-tions. The visual hull sampling process attempts to inter-sect an object’s projection cone with the cones of minimal subsets of other similar objects among

To recover a version of Barro's (1979) `random walk' tax smoothing outcome, we modify Lucas and Stokey's (1983) economy to permit only risk-free debt. This imparts near unit root like behavior to government debt, independently of the government expenditure process, a realistic

flourished in recent decades (Diener, Suh, Lucas, & Smith, 1999; Kahneman, Diener, & Schwarz, 1999), with increasing recognition of the different streams of inquiry guiding this broad domain. Ryan and Deci’s (2001) integrative review organized the field of well-being into two broad traditions: one

A Lucas cube 3 ^ can be defined as the graph whose vertices are the binary strings of length n without either two consecutive l's or a 1 in the first and in the last position, and in which the vertices are adjacent when their Hamming distance is exactly 1. A Lucas cube 5E „ is very similar

of Phaseolus vulgaris e Vigna unguiculata, irrigated with different salinity levels. The treatments were distributed in a completely randomized design, in factorial arrangement 6 x 2 referring to electrical conductivity levels of water irrigation (ECw), as follows: 0.0; 1.5; 3.0; 4.5; 6.0 e 7.5 dS m-1 and two

I solve for asset prices, expected returns, and the term structure of interest rates in an endowment economy in which a representative agent with power utility consumes the dividends of multiple assets. The assets are Lucas trees; a collection of Lucas trees is a Lucas orchard. The model replicates
