Texte intégralThe exponential growth of the Internet requires regular monitoring of network metrics. This thesis focuses on round-trip delays and the possibility of addressing the problems of missing data and multivariate segmentation. The first contribution includes the orchestration of delay measurement campaigns, as well as the development of a simulator that generates end-to-end delay traces. The second contribution of this thesis is the introduction of two missing data completion methods. The first is based on non-negative matrix factorization, while the second uses collaborative neural filtering. Tested on synthetic and real data, these methods demonstrate their efficiency and accuracy. The third contribution of this thesis involves multivariate delay segmentation. This approach is based on hierarchical clustering and is implemented in two stages. Firstly, the delay time series are grouped to obtain, within the same group, series with similar and synchronous variations and trends. Next, the multivariate segmentation step collectively and jointly segments the series within each group. This step uses hierarchical clustering followed by post-processing using the Viterbi algorithm to smooth the segmentation result. This method was tested on real delay traces from two major events affecting two Internet Exchange Points (IXPs). The results show that this method approximates the state-of-the-art in segmentation, while significantly reducing computing speed and costs

Texte intégralThe topic of this thesis is data-analysis on images from two-dimensional electrophoretic gels. Because of the complexity of these images, there are numerous steps and approaches to such an analysis, and no “golden standard” has yet been established on how to produce the desired output. In this thesis focus is put on two essential fields concerning 2D-gel analysis; registration of images by segregation and protein spot identification, and data-analysis on the output of such a registration by multivariate methods. Image segmentation is mainly concerned with the task of identifying individual protein spots in a gel-image. This has generally been the natural starting point of all methods and procedures developed since the introduction of 2D-gels in the mid-seventies, simply because this best reproduces the results created by a human analyst, who manually identify protein-spot entities. The amount of data produced in a 2D-gel experiment can be quite large, especially in multiple gels where the human analyst is dependent on additional statistical data-analytical tools to produce results. Because of the correlated nature of most gel-data, analysis by multivariate methods is natural choice, and are therefore adopted in this thesis. The goal of this thesis is to introduce the above mentioned procedures at different stages in the analysis pipeline where they are not yet fully exploited, rather than to improve already existing algorithms. In this way new insight and ideas on how to handle data from 2D-gel experiments are achieved. The thesis starts with a review of segmentation methodology, and introduces a selected procedure used to identify protein spots throughout. Output from the segmentation is then used to create a multivariate spot-filtering model, which aims to separate protein spots from noise and artefacts often creating problems in 2D-gel analysis. Lately the use of common spot boundaries in multiple gels have been the method of choice when gels are analysed. How such boundaries should be defined is an important subject of discussion, and thus a new method for defining common boundaries based on the individual segmentation of each gel is introduced. Segmentation may be a natural starting point when gels are analysed, but it is not necessarily the most correct. Often the introduction of fixed spot entities introduces restrictions to the data which cause problems at later stages in the analysis. Analysing pixels from multiple gels directly has no such restrictions, and it is shown in this thesis that the output of such an analysis based on multivariate methods can produce very useful results. It can also give insight to the data problematic to achieve with the spot boundary approach. At last in the thesis an improved pixel-based approach is introduced, where a less restricted segmentation is used to reduce and concentrate the amount of data analysed, improving the final output.

Texte intégralHierarchical image representations are widely used in image processing to model the content of an image in the multi-scale structure. A well-known hierarchical representation is the tree of shapes (ToS) which encodes the inclusion relationship between connected components from different thresholded levels. This kind of tree is self-dual, contrast-change invariant and popular in computer vision community. Typically, in our work, we use this representation to compute the new distance which belongs to the mathematical morphology domain. Distance transforms and the saliency maps they induce are generally used in image processing, computer vision, and pattern recognition. One of the most commonly used distance transforms is the geodesic one. Unfortunately, this distance does not always achieve satisfying results on noisy or blurred images. Recently, a new pseudo-distance, called the minimum barrier distance (MBD), more robust to pixel fluctuation, has been introduced. Some years after, Géraud et al. have proposed a good and fast-to-compute approximation of this distance: the Dahu pseudodistance. Since this distance was initially developed for grayscale images, we propose here an extension of this transform to multivariate images; we call it vectorial Dahu pseudo-distance. This new distance is easily and efficiently computed thanks to the multivariate tree of shapes (MToS). We propose an efficient way to compute this distance and its deduced saliency map in this thesis. We also investigate the properties of this distance in dealing with noise and blur in the image. This distance has been proved to be robust for pixel invariant. To validate this new distance, we provide benchmarks demonstrating how the vectorial Dahu pseudo-distance is more robust and competitive compared to other MB-based distances. This distance is promising for salient object detection, shortest path finding, and object segmentation. Moreover, we apply this distance to detect the document in videos. Our method is a region-based approach which relies on visual saliency deduced from the Dahu pseudo-distance. We show that the performance of our method is competitive with state-of-the-art methods on the ICDAR Smartdoc 2015 Competition dataset
