fragmentation, or breaking apart of habitats, is one of the major causes of decline in biological diversity. mature ecosystems, especially dense forests are very sensitive to this phenomenon and roads are one of the major causes of fragmentation in forest landscapes. present investigation aims to trace landscape fragmentation in dense forests of golestan national park in northeast of iran betw...

This paper presents a structure-from-motion system which delivers dense structure information from a sequence of dense optical ows. Most traditional feature-based approaches cannot be extended to compute dense structure due to impractical computational complexity. We demonstrate that by decomposing uncertainty information into independent and correlated parts we can decrease these complexities ...

Realistic 3D face model is desired in various applications such as face recognition, games, avatars, animations, and etc. Construction of 3D face model is composed of 1) building a face shape model and 2) rendering the face shape model. Thus, building a realistic 3D face shape model is an essential step for realistic 3D face model. Recently, 3D morphable model is successfully introduced to deal...

Modern deep neural networks have a large number of parameters, making them very hard to train. We propose DSD, a dense-sparse-dense training flow, for regularizing deep neural networks and achieving better optimization performance. In the first D (Dense) step, we train a dense network to learn connection weights and importance. In the S (Sparse) step, we regularize the network by pruning the un...

during the study of powdery mildew related to erysiphaceae family from abardeh region in mashhad (khorasan-e-razavi province), one species of rose (rosa persica michx.ex juss, summer 2006) with symptoms of powdery mildew was collected. the symptoms observed with the naked eye including the dense cottony shape mycelia infected the leaf surfaces as well as some parts of the stem. mycelia were den...

The dynamical system (f,R) is introduced and some of its properties are investigated. It is proven that there is an invariant set Λ on which the periodic points of f are dense.

Let t be any abstract measure of computational complexity, and let L denote the specific measure of memory resource (tape) on one tape Turing machines. De~ote by R:() the class of all total functions whose t-complexity is bounded by the function t() almost everywhere. Call such classes t-complexity classes. We are interested in relationships among these classes, under proper set inclusion (C). ...

Motivated by structural decompositions and other asymptotic properties of graphs we define the notions in the title and show the wide spectrum of examples of nowhere dense graphs. This has several algorithmic consequences and it generalizes and improves earlier results.

This paper presents a technique for estimating the threedimensional velocity vector field that describes the motion of each visible scene point (scene flow). The technique presented uses two consecutive image pairs from a stereo sequence. The main contribution is to decouple the position and velocity estimation steps, and to estimate dense velocities using a variational approach. We enforce the...
