hyperspectral sensors provide a large number of spectral bands. this massive and complex data structure of hyperspectral images presents a challenge to traditional data processing techniques. therefore, reducing the dimensionality of hyperspectral images without losing important information is a very important issue for the remote sensing community. we propose to use overlap-based feature weigh...

Assessment of pavement distresses is one of the important parts of pavement management systems to adopt the most effective road maintenance strategy. In the last decade, extensive studies have been done to develop automated systems for pavement distress processing based on machine vision techniques. One of the most important structural components of computer vision is the feature extraction met...

Determining the structural class of a given protein can provide important information about its functionality and its general tertiary structure. In the last two decades, the protein structural class prediction problem has attracted tremendous attention and its prediction accuracy has been significantly improved. Features extracted from the Position Specific Scoring Matrix (PSSM) have played an...

We present a user-assisted approach to extracting and visualizing structural features from point clouds obtained by terrestrial and airborne laser scanning devices. We apply a multi-scale approach to express the membership of local point environments to corresponding geometric shape classes in terms of probability. The structural classes we are dealing with are surfaces, curves, and critical po...

We present depth-resolved spatial-domain low-coherence quantitative phase microscopy, a simple approach that utilizes coherence gating to construct a depth-resolved structural feature vector quantifying sub-resolution axial structural changes at different optical depths within the sample. We show that this feature vector is independent of sample thickness variation, and identifies nanoscale str...

Protein structural class’s knowledge plays an important role in understanding the folding mode of protein. The prediction of protein structural classes as a transitional stage of the secondary structure of the protein to the tertiary structure is considered to be an important and challenging task. In this paper, PSI-BLAST profile is used to extract the evolutionary information of protein, and t...

topicalization and focus movement have been discussed in literature with respect to a vriety of their properties. in persian, syntactic objects within tense phrase, including phrasal arguments, may freely be displaced to a higher position and the reordering of these elements is mainly considered to be the result of discourse functional elements such as topic and focus. the present study is an e...
