Special Issue Texture and Color in Image Analysis

Special Issue on Image Processing and Analysis

Conceptualizing away the sketch processing details in a user interface will enable general users and domain experts to create more complex sketches. There are many domains for which sketch recognition systems are being developed. But, they entail image-processing skill if they are to handle the details of each domain, and also they are lengthy to build. The implemented system’s goal is to enabl...

Local quaternion Fourier transform and color image texture analysis

Color images can be treated as two-dimensional quaternion functions. For analysis of quaternion images, a joint space-wavenumber localized quaternion S transform (QS) is presented in this study for a simultaneous determination of the local color image spectra. The QS transform uses a two-dimensional Gaussian localizing window that scales with wavenumbers. Rotation invariance, invertibility and ...

Special issue on 3-D image analysis and modeling

I N RECENT DAYS, three-dimensional (3-D) images are widely used for many applications, and recent advances in computer performances have extremely extended the range of applicability. This vitality is witnessed by the increasing number of papers presented in past conferences and by the number of research projects related to 3-D images. Three-dimensional data are inherently more informative, in ...

Special issue on Shape Modeling in Medical Image Analysis

Exploring and using anatomical shape properties plays an increasingly important role in many medical imaging and image processing applications, including structural analysis and modeling, medical image segmentation, image registration, computer aided diagnosis, tracking and longitudinal analysis, and medical navigation. For example, prior knowledge on the shape of interest has been used to achi...
