Using more than three shading images gives more This paper proposes a new method to recover the sign of local Gaussian curvature from multiple shading images (more than three). The required information to recover the sign of Gaussian curvature is obtained by applying Principal Components Analysis (PCA) to the normalized irradiance measurements. The sign of the Gaussian curvature is recovered ba...

Intrinsic images represent the underlying properties of a scene such as illumination (shading) and surface reflectance. Extracting intrinsic images is a challenging, ill-posed problem. Human performance on tasks such as shadow detection and shape-from-shading is improved by adding colour and texture to surfaces. In particular, when a surface is painted with a textured pattern, correlations betw...

in this research, an iterative approach is employed to recognize and classify control chart patterns. to do this, by taking new observations on the quality characteristic under consideration, the maximum likelihood estimator of pattern parameters is first obtained and then the probability of each pattern is determined. then using bayes’ rule, probabilities are updated recursively. finally, when...

The perception of shading-defined form results from an interaction between shading cues and the frames of reference within which those cues are interpreted. In the absence of a clear source of illumination, the definition of 'up' becomes critical to deducing the perceived shape from a particular pattern of shading. In our experiments, twelve subjects adjusted the orientation of a planar disc pa...

this study aimed to determine the effects of different shading ratio and covers on “sultana seedless” table grape quality and storability. grapevines were covered at the veraison stage with 3 shading nets (0, 35, and 75% shading), which were then replaced with covering materials including polypropylene cross-stitch (pc), life pack (lp) and mogul (mg), just before harvest. harvested grapes in al...

Recently, many methods have been proposed for face reconstruction from multiple images, most of which involve fundamental principles of Shape from Shading and Structure from motion. However, a majority of the methods just generate discrete surface model of face. In this paper, Bspline Shape from Motion and Shading (BsSfMS) is proposed to reconstruct continuous B-spline surface for multiview fac...

Graphics hardware evolution in the past year has been highlighted by improved shading resources, the introduction of dynamic flow control and the emergence of multi-GPU system configurations. Executed program length increased substantially and register availability became more affordable. As a result, compiler support for segmenting a shading program to fit hardware constraints has diminished a...

ABSTRACT The study aimed to evaluate the growth of ornamental cherry tomato plants in different protected environments and reflective materials on cultivation benches. As there were no repetitions environments, each environment was considered an experiment. In environment, experimental design used completely randomized with five replications three per plot. From analysis individual variances ev...
