IN APPAREhT MOTION
نویسنده
چکیده
A region in an alternated pair of random-dot patterns was uniiormty displaced. It U:E perceiled ‘1s a segregated. coherently moving shape only if the displacement was smdii. The hmit on the displacement was Its absolute size (maximum about 15’) rather than the number of elements’ widths. Segregation due to apparent motion did not occur if the two patterns were exposed to diKerent eyes. These conditions for segregation differ from those classically found for apparent motion. Perceptual segreqtion ma> be due to the activity oflow-levei motion detectors of limited spatial range, while classicsi apparent motion with largx displacements involves a different process. The problem of selection among alternative possible interactions of stimulus elements in apparent motion is discussed.

Advanced Motion Correction Methods in PET
With the arrival of increasingly higher resolution PET systems, small amounts of motion can cause significant blurring in the images, compared to the intrinsic resolutions of the scanners. In this work, we have reviewed advanced correction methods for the three cases of (i) unwanted patient motion, as well as motions due to (ii) cardiac and (iii) respiratory cycles. For the first type of ...
متن کاملComparison between linear and nonlinear models for surge motion of TLP
Tension-Leg Platform (TLP) is a vertically moored floating structure. The platform is permanently mooredby tendons. Surge equation of motion of TLP is highly nonlinear because of large displacement and it should be solved with perturbation parameter in time domain. This paper compare the dynamic motion responses of a TLP in regular sea waves obtained by applying three method in time domain usin...

متن کاملEffect of Step Length and Step Period on Walking Speed and Energy Consumption: a Parameter Study
Stability and performance are two main issues in motion of bipeds. To ensure stability of motion, a biped needs to follow specific pattern to comply with a stability criterion such as zero moment point. However, there are infinity many patterns of motion which ensure stability, so one might think of achieving better performance by choosing proper parameters of motion. Step length and step perio...

A direct method called fixation is introduced for solving the general motion vision problem, arbitrary motion relative to an arbitrary environment. This method results in a linear constraint equation which explicitly expresses the rotational velocity in terms of the translational velocity. The combination of this constraint equation with the Brightness-Change Constraint Equation solves the gene...
