Rapidly generate high-precision True Digital Orthophoto (TDOM) and Digital Surface Model (DSM) from photos. The algorithm is optimized according to the different scenarios to significantly improve processing efficiency, effectively avoid image warping and deformation, and obtain detailed and accurate measur...
The properties of the initial schedule make it possible to take the optimal exchange at each iteration, leading to a linear-time algorithm. This algorithm can find thus valid schedules for several thousands of teams in less than 1 min. It is still an open question whether the SLSP can be ...
Guided by gut sensory cues, humans and animals prefer nutritive sugars over non-caloric sweeteners, but how the gut steers such preferences remains unknown. In the intestine, neuropod cells synapse with vagal neurons to convey sugar stimuli to the brain
There is no way to avoid this problem without somehow changing the algorithm in a fundamental way. Even if our GPU supports dynamic parallelism (as NVIDIA Tesla K20 does), we cannot avoid the fact that every node is dependent on the results of its parent. We have to finish processing the...
一种最坏情况线性运行时间的选择算法 - The missing worst-case linear-time Select algorithm in CLRS. 选择算法也就是求一个无序数组中第K大(小)的元素的值的算法,同通常的Top K等算法密切相关。 在CLRS中提到了一种最坏情况线性运行时间的选择算法,在书中给出了如下的文字描述(没有直接给出伪代码)。
Because we are interested in watching the evolution of the flow over time, an incremental numerical solution suits our needs.As with any algorithm, we must divide the solution of the Navier-Stokes equations into simple steps. The method we use is based on the stable fluids technique d...
The first is that the input to the feedforward network is more accurate. The second is that the resulting network has a purely feedforward architecture, and therefore a more efficient algorithm can be used for training. This network is discussed in more detail in Design Time Series ...
To do so, the sample image area was divided into two parts using the spatial k-means algorithm; one of the clusters corresponding to the tissue sample and the other – to the sample-free matrix-covered surface of the glass slide. The mapping of the clusters to the sample and the ...
► The longest path problem is a well-known NP-hard problem and so far it has been solved polynomially only for a few classes of graphs. ► We give a linear-time algorithm for finding a longest path between any two given vertices in a rectangular grid graph. ► It is shown that ...
In the following sections, we describe how the GS unit can be used for algorithms with variable-length output, making the GPU a more viable compute target for computer vision. 41.4.3 The Hough Transform The Hough transform, a classical computer vision algorithm for detecting str...
