This guide is your key to unlocking the power of histograms, the most important tool in your kit for nailing exposure with every shot. I will not only teach you how to understand histograms but also show you practical techniques for using them in real-world photography. LATEST VIDEOS Additiona...
For example, in a video database the user might be asked to rate the quality of selection on a scale ranging from “high relevance” to “low relevance”. An example of a user-study interface for video retrieval is shown in Fig. 11. Sign in to download full-size image FIGURE 11. ...
In particular, maximum likelihood, inference function for margins, and canonical maximum likelihood estimation methods are proposed. A numerical study helps to ascertain which copulas are best to use in various cases, and thence to calculate the covariances. The results are applied to a real dataset...
For an example, see Compute the Histogram of Real and Complex Data. To track the frequency distribution of inputs over a period of time, select the Running histogram parameter. When the input is complex, the block sorts the elements by their magnitude....

We propose an efficient solution enabling interactive LOD selection on large, out-of-core volumes and show its efficacy on two real data sets from different problem domains. 展开 关键词: Time-varying volume visualization Level of detail selection Multivariate volume visualization ...

The same results are also presented for data described by continuous density functions (empiric or estimated). An application to real data is performed to illustrate the effects of the new distance using dynamic clustering. 展开 关键词: histogram data Wasserstein distance Mahalanobis distance inertia ...
The SSD algorithm with an acceleration strategy is used for the tracking step, whereas the re- identification stage is realized using two techniques: the intersection for temporal association and the histogram comparison. The global system was tested on a real data set collected by three cam- ...
