Abstract:
This work contributes to the field of Content-based Image Retrieval (CBIR) particularly texture-based retrieval. The main goal of this work is to enable the user to navigate through a large image database without making any query in specific language. To achieve this goal, we divided the work into two main parts. The first part involves the extraction of a texture model made of relevant attributes. We proposed to study two models of texture: the co-occurrence matrices and Tamura's attributes. The selection and validation of the model features are based on several applications that we have proposed in this thesis after reducing the dimension of the representation's space. Then, navigation is achieved using Galois' lattices with a simple HTML interface while passing through a phase of interpretation of numerical model texture into a semantic model. The problem of the transcription from the numerical values to the semantics is regarded as a problem of discretisation of continuous attributes. Another problem occurs when the size of the database of images increases: the performance of the navigation system are deteriorating. To overcome this problem, we propose to use techniques of summarisation to create summaries that help users to navigate through target collections instead of the whole database.
