    Full text link
    From The late 90th, "Skin Detection" becomes one of the major problems in image processing. If "Skin Detection" will be done in high accuracy, it can be used in many cases as face recognition, Human Tracking and etc. Until now so many methods were presented for solving this problem. In most of these methods, color space was used to extract feature vector for classifying pixels, but the most of them have not good accuracy in detecting types of skin. The proposed approach in this paper is based on "Color based image retrieval" (CBIR) technique. In this method, first by means of CBIR method and image tiling and considering the relation between pixel and its neighbors, a feature vector would be defined and then with using a training step, detecting the skin in the test stage. The result shows that the presenting approach, in addition to its high accuracy in detecting type of skin, has no sensitivity to illumination intensity and moving face orientation.Comment: 9 Pages, 4 Figure

    Get PDF
    Classic papers are novel facilities of Google scholar. These papers were first developed by Google scholar in May 2017. Classic papers have been considered highly cited papers since last 10 years. Effective authors, institutions, universities, and countries on improving science can be identified by analyzing the papers. Therefore, this study aims to examine characteristics of classic papers of Library and Information Science (LIS). This study will use Scientometrics indicators. The study sample includes LIS classic papers. To gather the data, some databases such as Google scholar, Web of Science, and Scopus are applied. Excel and SPSS applications are used for descriptive and statistical analyses. The study data indicate that Scientometrics journal covers most classic papers on LIS (5 papers). 60% of the papers are written by more than one author. A paper of “Usage Pattern of Collaborating Tagging System” is highly cited paper of LIS with 3051 and 1308 citations on Google scholar and Scopus respectively. Analysis of authors’ affiliation shows that American universities and institutions play considerable role in LIS classic papers. The data of statistical tests indicate that there is a positive significant correlation between citations of classic papers of Google scholar, Scopus and Web of Science

    Get PDF
    Introduction: Bibliotherapy is a low-cost and safe way to treat mental health problems. Given that the success of bibliotherapy depends on the positive attitude and familiarity of those involved in this therapy method, this study aims to investigate the familiarity, attitude, and use of bibliotherapy by psychologists working in counseling centers and the barriers and limitations in using bibliotherapy. Methods: In this practical research, conducted using an analytic survey method in 2020, 101 psychologists working in counseling centers in Hamadan province, Iran, were selected by the census. The survey response rate was 100 %. All data for this study were collected using a researcher-made questionnaire. Its reliability (using the indicator of Cronbach's alpha) and validity (using two indicators of CVI and CVR) were confirmed. The data were analyzed using SPSS software version 25 using frequency distribution, Mann-Whitney, Chi-square, and Kruskal-Wallis tests. Results: The results showed that more than half of the participants (53.5%) were moderately familiar with the bibliotherapy, and their level of familiarity was less than average; more than half of the participants (55.4%) used moderate bibliotherapy to treat their patient's problems, and their use rate was low to medium levels. However, psychologists' attitudes toward bibliotherapy are positive and higher than average. Conclusion: Despite bibliotherapy's effectiveness and psychologists' favorable view of it, awareness and utilization remain low, highlighting the need for strategies to enhance the adoption of this therapeutic approach
