We investigate Generative Adversarial Networks (GANs) to model one particular kind of image: frames from TV cartoons. Cartoons are particularly interesting because their visual appearance emphasizes the important semantic information about a scene while abstracting out the less important details, but each cartoon series has a distinctive artistic style that performs this abstraction in differen...

The growth evolution of hexagonal GaN pyramids are investigated under various growth conditions. The hexagonal GaN pyramids were grown by hot-wall metal organic chemical vapor deposition – process (hot-wall MOCVD) on a (0001) oriented GaN template. We concluded the growth of the hexagonal GaN pyramids can be divided into two different regimes defined by the adsorption kinetics of the {1101} sur...

A motion estimation algorithm using wavelet approximation as an optical ow model has been developed to estimate accurate dense optical ow from an image sequence. This wavelet motion model is particularly useful in estimating optical ows with large displacement. Traditional pyramid methods which use the coarse-tone image pyramid by image burring in estimating optical ow often produce incorrect r...

Crowd counting is one of the most challenging issues in computer vision community for safety and security through surveillance systems. It has extensive range applications, such as disaster management, event detection, intelligence gathering analysis, public control, traffic monitoring, design spaces, anomaly detection military. Early approaches still encounter many like non-uniform density dis...

Pyramid annotation makes it possible to evaluate quantitatively and qualitatively the content of machine-generated (or human) summaries. Evaluation methods must prove themselves against the same measuring stick – evaluation – as other research methods. First, a formal assessment of pyramid data from the 2003 Document Understanding Conference (DUC) is presented; this addresses whether the form o...

A given (overcomplete) discrete oriented pyramid may be converted into a steerable pyramid by interpolation. We present a technique for deriving the optimal interpolation functions (otherwise called steering coefficients). The proposed scheme is demonstrated on a computationally efficient oriented pyramid, which is a variation on the Burt and Adelson pyramid. We apply the generated steerable py...

-The stochastic pyramid is introduced in landscape ecology in order to propose a spatial organization model of ecological units in river floodplains. It consists in articulating this parallel generator of random patterns with ecological processes. The stochastic pyramid, based on a hierarchy of seed structures, is used to make regions grow in order to obtain random patterns relating to an a pri...

Rendering of textured terrain models has become a widely used technique in the field of GIS applications and virtual reality. In this paper, we propose a framework based on tile-pyramid model and linear quadtree tile-index, which enable the real-time rendering of out-of-core terrain data sets while guaranteeing geometric and texture accuracy. The digital elevation model tile pyramid and the ort...

A temporal image sequence increases the dimension of the data by simply stacking images above each other. This further raises the computational complexity of the processes. The typical content of a pixel or a voxel is its grey or color value. With some processing, features and fitted model parameters are added. In a pyramid these values are repeatedly summarized in the stack of images or image ...
