Image Retrieval and Annotation Using Maximum Entropy
In this work, we present and discuss our participation in the four tasks of the ImageCLEF 2006 Evaluation. In particular, we present a novel approach to learn feature weights in our content-based image retrieval system FIRE. Given a set of training images with known relevance among each other, the retrieval task is reformulated as a classification task and then the weights to combine a set of f...
متن کاملContent-based Image Retrieval Using Entropy and Fractal Coding
Describing and extracting image’s feature is a key question in content-based image retrieval system, and this paper puts forward a novel image retrieval method using image information entropy and fractal coding. First, compared with a given threshold computed from the inquired image, each image in the database is classified by computing its image entropy. Second, the inquired image’s fractal co...
متن کاملUsing Statistical Moment Invariants and Entropy in Image Retrieval
Although content-based image retrieval (CBIR) is not a new subject, it keeps attracting more and more attention, as the amount of images grow tremendously due to internet, inexpensive hardware and automation of image acquisition. One of the applications of CBIR is fetching images from a database. This paper presents a new method for automatic image retrieval using moment invariants and image en...
متن کاملImage Indexing and Retrieval using Cross-Entropy Measures
| In content-based image indexing and retrieval, images are indexed based on the image attributes like, color, texture, shape. These attributes are used in enabling image retrieval based on query images. A user provides a sample image and the images in the database that are similar to the sample image are retrieved. Image content is represented in the form of feature vectors or histograms. In t...
متن کاملSemiautomatic Image Retrieval Using the High Level Semantic Labels
Content-based image retrieval and text-based image retrieval are two fundamental approaches in the field of image retrieval. The challenges related to each of these approaches, guide the researchers to use combining approaches and semi-automatic retrieval using the user interaction in the retrieval cycle. Hence, in this paper, an image retrieval system is introduced that provided two kind of qu...
