We used Rapid Serial Visual Presentation (RSVP) to examine the tuning of macaque inferior temporal cortical (IT) neurons to 5 sets of 25 shapes each that varied systematically along pre-defined shape dimensions. A comparison of the RSVP technique using 100 ms presentations with that using a longer duration showed that shape preference can be determined with RSVP. Using relatively complex shapes...

The main goal in image analysis is to detect and recognize objects of interest present in the observed images. Imaged objects can be characterized in many ways: according to their colors, textures, shapes, movements, and locations. The past decade has seen large efforts in modeling and analysis of pixel values or textures in images to attain these goals albeit with limited success. An emerging ...

The Schur-positivity order on skew shapes is defined by B ≤ A if the difference sA − sB is Schur-positive. It is an open problem to determine those connected skew shapes that are maximal with respect to this ordering. A strong necessary condition for the Schur-positivity of sA−sB is that the support of B is contained in that of A, where the support of B is defined to be the set of partitions λ ...

an analytical model is proposed and an analysis is conducted for solid oxide fuel cells with goals of higher power densities. the analytical model is designed to help optimize the size, spacing, and geome-trical shapes of current collectors. the model fully considers the ohmic, species concentration, and activa-tion polarizations. from the analysis of several cases, it is recommended that 3d pi...

We present a novel interaction system, ‘‘Shape-It-Up’’, for creative expression of 3D shapes through the naturalistic integration of human hand gestures with a modeling scheme dubbed intelligent generalized cylinders (IGC). To achieve this naturalistic integration, we propose a novel paradigm of shape–gesture–context interplay (SGCI) wherein the interpretation of gestures in the spatial context...

Shapes are a concise way to describe temporal variable behaviors. Some commonly used shapes are spikes, sinks, rises, and drops. A spike describes a set of variable values that rapidly increase, then immediately rapidly decrease. The variable may be the value of a stock or a person’s blood sugar levels. Shapes are abstract. Details such as the height of spike or its rate increase, are lost in t...

The concept of elongation is generally well understood. However, there is no clear, precise, mathematical definition of elongation in any dictionary we could find. We propose that the definition of elongation should overlap with the definition of linearity since we will show that these two measures produce results that are highly correlated when applied to different types of 2D shapes. Our expe...
