Content-Based Image Retrieval (CBIR) is one of the most active hot spots in the current research field of multimedia retrieval. According to the description and extraction of visual content (feature) of the image, CBIR aims to find images that contain specified content (feature) in the image database. In this paper, several key technologies of CBIR, e. g. the extraction of the color and texture...

In this paper we propose a sketch-based interface for drawing and generating a realistic 3D human face with texture. The free form sketch-based interface allows a user to intuitively draw a portrait as in traditional pencil sketching way. Then, the user’s drawing is automatically reshaped to an accurate natural human facial shape with the guidance of a statistical description model, and an arti...

Current content-based image retrieval techniques can typically perform efficient and effective searches on heterogeneous image databases. This contribution deals with an approach based on the integration of color and texture description which is applied to a very homogeneous database: a blood image bank. The content of images is very similar and therefore it becomes imperative to use very preci...

Unconstrained authentication is an important component for personal automated systems and human-computer interfaces. Existing solutions mostly use face as the primary object of analysis. The performance of face-based systems is largely determined by the extent of deformation caused in the facial region and amount of useful information available in occluded face images. Periocular region is a us...

We have developed a robust method for automatic image segmentation based on a local multiscale texture description. First, we apply a bank of Gabor filters to the input, producing a joint representation of the image in the spatial and spatial-frequency domains. Then we obtain local texture descriptors, by basically computing the modulus of the filters' complex output. These texture descriptors ...

The goal of this research is to study the anisotropic material behavior during forming processes, represented by both complex yield loci and kinematic-isotropic hardening models. A first part of this paper describes the main concepts of the ‘Stress-strain interpolation’ model that has been implemented in the non-linear finite element code Lagamine. This model consists of a local description of ...

The retinal nerve fiber layer (RNFL) is a vital part of human visual system, which can be directly observed by the fundus camera. This paper describes a method for glaucomatous retina detection based on Texture and Fractal description, followed by classification using support vector machine classifier. The color fundus images are used, in which the region of retinal nerve fibers are analyzed. I...

This paper describes a new approach to the characterization of texture properties at multiple scales using the wavelet transform. The analysis uses an overcomplete wavelet decomposition, which yields a description that is translation invariant. It is shown that this representation constitutes a tight frame of l(2) and that it has a fast iterative algorithm. A texture is characterized by a set o...

Thyroid is one of the endocrine Gland. Thyroid can be classified into normal, nodule and cancers thyroid. The characterization of the thyroid tissue in digital image processing techniques offer’s the texture description and using the ultrasound images. In this paper describe the various type of feature extraction techniques characterization and classification method. The texture characterizatio...

A shape based descriptor in image retrieval is proposed in this paper. It is focused on developing soft computing efficiency and novelty in image processing. The algorithm calculates a histogram based on the shape descriptor, representing texture feature of an image at high level (object oriented) effectively. By integrating the algorithms in key point detector with shape descriptor, the new me...
