We present an approach for recognizing human walking movements using low-level motion regularities and constraints. Biomechanical features for classification are automatically extracted from video sequences of walkers. A multiplicative classification rule using statistical distances is then used to determine whether an unknown motion is consistent with normal walking patterns. Recognition resul...
abstract the current study examined the role of emotional intelligence and motivation on language learning of efl learners in iranian context. the participants of this study were 162 female and 100 male junior high school students. these participants were selected by convenient sampling method. to carry out the study two questionnaires were administered to the participants. first, the adap...
during the process of reading, sometimes learners use ineffective and inefficient strategies and some factors may influence their use of strategies. perhaps critical thinking is one of these factors. this study aims to identify those categories of reading strategies that are mostly used by iranian efl learners and to see if there is any significant relationship between the critical thinking abi...
The left ventricle tracking in planar scintigraphic images is an important step to study the coronary state. However, it is not as simple as we thought, because of the bad quality of these images. The study of the related work showed that classic methods based on low level image characteristics failed to localize the ventricle. In this paper, we suggest using a method based on a priori knowledg...
Anatomical shape variations are typically difficult to model and parametric or hand-crafted models can lead to ill-fitting segmentations. This difficulty can be addressed with a framework like autocontext, that learns to jointly detect and regularize a segmentation. However, mis-segmentation can still occur when a desired structure, such as the spinal cord, has few locally distinct features. Hi...
Companies use Extract-Transform-Load (Etl) tools to save time and costs when developing and maintaining data migration tasks. Etl tools allow the definition of often complex processes to extract, transform, and load heterogeneous data into a data warehouse or to perform other data migration tasks. In larger organizations many Etl processes of different data integration and warehouse projects ac...
We propose a mid-level melody-based representation that incorporates melodic, rhythmic and structural aspects of a music signal and is useful for calculating audio similarity measures. Most current approaches to music similarity use either low-level signal features, such as MFCCs that mostly capture timbral characteristics of music and contain little semantic information, or require symbolic re...
The credibility of website is a sort of psychological feeling, in other words, a sense of trust and its intensity towards the enterprise’s website produced by the customers from individual or collective perspective. The credibility of website has become a decisive factor for the website’s survival and an important driving force of promotion and market expansion. Currently, the credibility of we...
