Full textError correcting codes are tools whose initial function is to correct errors caused by imperfect communication channels. In a non-cooperative context, there is the problem of identifying unknown codes based solely on knowledge of noisy codewords. This problem can be difficult for certain code families, in particular LDPC codes which are very common in modern telecommunication systems. In this thesis, we propose new techniques to more easily recognize these codes. At the end of the 1970s, McEliece had the idea of redirecting the original function of codes to use in ciphers; thus initiating a family of cryptographic solutions which is an alternative to those based on number theory problems. One of the advantages of code-based cryptography is that it seems to withstand the quantum computing paradigm; notably thanks to the robustness of the generic decoding problem. The latter has been thoroughly studied for more than 60 years. The latest improvements all rely on using algorithms for finding pairs of points that are close to each other in a list. This is the so called near-collisions search problem. In this thesis, we improve the generic decoding by asking in particular for a new way to find close pairs. To do this, we use list decoding of Arikan's polar codes to build new fuzzy hashing functions. In this manuscript, we also deal with the search for pairs of far points. Our solution can be used to improve decoding over long distances. This new type of decoding finds very recent applications in certain signature models

Full textThe increasing of image databases requires the use of a content-based image retrieval system (CBIR). A such system consist first to describe automatically the images, visual properties of each image are represented as multidimensional vectors called descriptors. Next, finding similar images to the query image is achieved by searching for the nearest neighbors of each descriptor of the query image. In this thesis, we propose a new method for indexing multidimensional bases with the search algorithm of nearest neighbors adapted. The originality of our multidimensional index is the disposition of the bounding forms avoiding overlapping. Indeed, the overlapping is one of the main drawbacks that slow the search of nearest neighbors search. Our index with its search algorithm speeds the nearest neighbors search while doing an exact search. Our method has been integrated and tested within a real content-based image system. The results of tests carried out show the robustness of our method in terms of accuracy and speed in search time

Full textIn the first part of this thesis, we are concerned by the nearest neighbour problem, applied on local image descriptors. We restricted ourselves to the SIFT descriptors because of its efficiency. The application of this work is the retrieval of similar images in large databases. First, we compare performances of linear search, on CPU and on GPU (graphic processors), and also when using partial distances. Then, we propose new hash functions t solve the approximate nearest neighbours problem. The hash functions we propose are based on a selection of a few distinctive dimensions per point. For the application of near duplicate retrieval, our algorithm is more efficient than state-of-the-art algorithms. Tested on a database containing 500. 000 images, it finds similar images in less than 300ms. Eventually, we show that it fits very simply within a Bag-Of-Features approach, and it retrieves mor images than kmeans based vocabularies. In a second part, we propose several results on the problem of multi-view 3D reconstruction. We first propose a robust method to obtain the 3D reconstruction of a car from a video sequence. Our system uses the hypothesis that the car is in linear translation in order to fit a point cloud with polynomial surfaces. Then, we propose an algorithm, not dedicated to cars, that uses SIFT descriptors to obtain the 3D surface from images of an object. The descriptors correspondences are searched between input images and virtual images of the temporary object. With this method, the reconstructed surface converges to the true surface object

Full textThe present work focuses on the technical feasibility study of i-GUIDE system which is a real time indoor navigation system dedicated to assist persons inside hypermarkets. We detailed its functional analysis. Then, we studied the impact of integrating the system inside hypermarkets. We opted for an UML design to describe its main functionalities and objects required. We presented architecture of i-GUIDE system based on RFID technology with an Android application. Furthermore, we introduced optimization approaches based on tabu search to compute the route visiting items existing in a shopping list for two problems. The first one treats the shortest path to pick up items and the second one adds a time constraint for promotional items. Before computing the shortest path, we introduced a method to determine distance between each two items existing in the hypermarket

Full textThe ease of publishing content on social media sites brings to the Web an ever increasing amount of user generated content captured during, and associated with, real life events. Social media documents shared by users often reflect their personal experience of the event. Hence, an event can be seen as a set of personal and local views, recorded by different users. These event records are likely to exhibit similar facets of the event but also specific aspects. By linking different records of the same event occurrence we can enable rich search and browsing of social media events content. Specifically, linking all the occurrences of the same event would provide a general overview of the event. In this dissertation we present a content-based approach for leveraging the wealth of social media documents available on the Web for event identification and characterization. To match event occurrences in social media, we develop a new visual-based method for retrieving events in huge photocollections, typically in the context of User Generated Content. The main contributions of the thesis are the following : (1) a new visual-based method for retrieving events in photo collections, (2) a scalable and distributed framework for Nearest Neighbors Graph construction for high dimensional data, (3) a collaborative content-based filtering technique for selecting relevant social media documents for a given event
