Many statistical shape analysis methods produce various types of data about the analyzed surfaces, such as p-value maps, distance maps, 3D difference vectors and local covariance matrices. This data is often too large and thus difficult to be properly evaluated on a qualitative basis. A visual representation of this data strongly simplifies qualitative evaluation by humans and thus greatly enha...

People readily perceive smooth luminance variations as being due to the shading produced by undulations of a 3-D surface (shape-from-shading). In doing so, the visual system must simultaneously estimate the shape of the surface and the nature of the illumination. Remarkably, shape-from-shading operates even when both these properties are unknown and neither can be estimated directly from the im...

Shape from shading uses a single light source, i.e., one image as input, to recover the shape information [4, 10, Traditional shape from shading techniques, using a single image, do not reconstruct accurate surfaces and have difficulty 17]. It has the advantage that it requires the least amount with shadow areas. Traditional shape from photometric stereo of input; however, this also introduces ...

Original scientific paper In present work, thermal transport considering heat radiation by oval heat source shape and heat transfer of molten moving electrode was presented. In present paper, an analytical solution was presented by aggregating temperature increments caused by applying liquid metal and heat radiation of moving electrode. The assumptions for the study were heat source of temperat...

In this research, a single-stage low-temperature hydrothermal synthesis route was successfully developed for preparation of Iron Disulfide. The prepared powder was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). These analyses showed that nanoparticles were well crystallized, pyrite was the main product and the shape of crystals was nanorod. Also, the influences...

A smooth object depicted in a photographwill often exhibit brightness variation, or shading. Various computational techniques have been developed that perform reasonably well in inferring shape from shading. However, these techniques typically require substantial prerequisite information if they are to evolve an estimate of surface shape. It is therefore interesting to consider how depth might ...

The Specialized Normal Form (SNF) is a unique (canonical) representation of Exclusive Sum-Of-Products (ESOP) expressions of a Boolean function. Hence this expansion of a Boolean function abstracts the form of the given ESOP expression and directs the focus to the properties of the function itself. This paper shows, how information about the given function can be detected from the shape of the S...

The apparent relief of monocularly viewed surfaces reversed when the order of light and shade was reversed relative to the position of a lamp observed the moment earlier. The pattern of shading was reversed either by illuminating from a direction opposite to that of the apparent direction of illumination or by inverting the illuminating image relative to the light source. The combination of bot...
