A Perceptual Approach for Image Representation and Retrieval: The Case of Textures
نویسنده
چکیده
Texture has been extensively studied and used in literature as it plays a very important role in human visual perception. Defining texture is not that easy; however some intuitive concepts can be defined about texture. Texture refers to the spatial distribution of grey-levels and can be defined as the repetition of one or several primitives in an image, in a deterministic or random way. Microtextures refer to textures with small primitives while macrotextures refer to textures with large primitives (Tomita & Tsuji, 1990; Tuceryan & Jain, 1993; Van Gool, Dewaele, & AbsTRACT

We present an approach based on multiple representations and multiple queries to tackle the problem of invariance in the framework of content-based image retrieval. We consider the case of textures. This approach, rather than to consider invariance at the representation level, considers it at the query level. We use two models to represent the visual content of textures, namely the autoregressi...
متن کاملImage Classification via Sparse Representation and Subspace Alignment
Image representation is a crucial problem in image processing where there exist many low-level representations of image, i.e., SIFT, HOG and so on. But there is a missing link across low-level and high-level semantic representations. In fact, traditional machine learning approaches, e.g., non-negative matrix factorization, sparse representation and principle component analysis are employed to d...
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...
متن کاملA Novel Method for Content Base Image Retrieval Using Combination of Local and Global Features
Content-based image retrieval (CBIR) has been an active research topic in the last decade. In this paper we proposed an image retrieval method using global and local features. Firstly, for local features extraction, SURF algorithm produces a set of interest points for each image and a set of 64-dimensional descriptors for each interest points and then to use Bag of Visual Words model, a cluster...
