Abstract - A fl exible multiscale and directional representation for images is proposed. The scheme combines directional fi lter banks with the Laplacian pyramid to provides a sparse representation for two- dimensional piecewise smooth signals resembling images. The underlying expansion is a frame and can be designed to be a tight frame. Pyramidal directional fi lter banks provide an effective method to implement the digital curvelet transform. The regularity issue of the iterated fi lters in the directional fi lter bank is examined.

This is a book about a revolution that quietly began a few years ago. It is about change in a function that you may not have given much thought to: your payment function. It may not be very different today from what it was 5 or 10 years ago. But here’s a guarantee: It will be very different 5 or 10 years from now. And best of all, it will cost less!

The software and hardware development fields evolved along separate paths through the end of the 20th century. We seem to have come full circle, however. The previously rigid hardware on which our programs run is softening in many ways. Embedded systems are largely responsible for this softening. These hidden computing systems drive the electronic products around us, including consumer products like digital cameras and personal digital assistants, office automation equipment like copy machines and printers, medical devices like heart monitors and ventilators, and automotive electronics like cruise controls and antilock brakes. Embedded systems force designers to work under incredibly tight time-tomarket, power consumption, size, performance, flexibility, and cost constraints. Many technologies introduced over the past two decades have sought to help satisfy these constraints. To understand these technologies, it is important to first distinguish the underlying embedded systems elements.

Supplemental information for a high-speed serial bus that integrates well with most IEEE standard 32-bit and 64-bit parallel buses is specified. It is intended to extend the usefulness of a low-cost interconnect between external peripherals, IEEE Std 1394-1995. This standard follows the ISO/IEC 13213:1994 Command and Status Register (CSR) architecture.

在图形中若于个边(edge)上加上一些值,此数值称为比重( weight ) 。而此图形称为比重图形(Weight Graph ) ,若weight是成本( cost )或距离( distance ) ,则称此图形为网路( Network )。根据Spanning Tree的定义,知一个图形可有许多不同spanning tree ,在network中找出一个具有最小成本( Cost )的Spanning tree ,则此Spanning tree称为最小成本生成树。

The object detector described below has been initially proposed by P.F. Felzenszwalb in [Felzenszwalb2010]. It is based on a Dalal-Triggs detector that uses a single filter on histogram of oriented gradients (HOG) features to represent an object category. This detector uses a sliding window approach, where a filter is applied at all positions and scales of an image. The first innovation is enriching the Dalal-Triggs model using a star-structured part-based model defined by a “root” filter (analogous to the Dalal-Triggs filter) plus a set of parts filters and associated deformation models. The score of one of star models at a particular position and scale within an image is the score of the root filter at the given location plus the sum over parts of the maximum, over placements of that part, of the part filter score on its location minus a deformation cost easuring the deviation of the part from its ideal location relative to the root. Both root and part filter scores are defined by the dot product between a filter (a set of weights) and a subwindow of a feature pyramid computed from the input image. Another improvement is a representation of the class of models by a mixture of star models. The score of a mixture model at a particular position and scale is the maximum over components, of the score of that component model at the given location.
