Textural analysis might give new insights into the quantitative characterization of metabolically active tumors. More than thirty textural parameters have been investigated in former F18-FDG studies already. The purpose of the paper is to declare basic requirements as a selection strategy to identify the most appropriate heterogeneity parameters to measure textural features. Our predefined requ...
This paper suggests a new image compression scheme, using the discrete wavelet transformation (DWT), which is based on attempting to preserve the texturally important image characteristics. The main point of the proposed methodology lies on that, the image is divided into regions of textural significance employing textural descriptors as criteria and fuzzy clustering methodologies. These textur...
In this work, a multisource features set for classification of landscape and, more specifically, forestry environments, is proposed and evaluated. Spectral features are obtained from Landsat-TM images; textural features are extracted from panchromatic high resolution aerial images, and digital elevation models are used to generate insolation maps. The data were georreferenced and resampled main...
Light Field (LF) imaging is a plenoptic data collection method enabling wide variety of image post-processing such as 3D extraction, viewpoint change and digital refocusing. Moreover, LF provides the capability to capture rich information about scene, e.g., texture, geometric information, etc. Therefore, quality assessment model for images needed poses significant challenges. Many Image Quality...
