pelvic inflammatory disease (pid) is a rare complication of transvaginal oocyte retrieval. it may result in failure of assisted reproductive techniques (art). during a 7 years period, 5958 transvaginal ultrasound-guided oocyte retrievals resulted in 10 cases of acute pid. eight out of 10 patients were diagnosed infertile because of endometriosis. two patients had mild ovarian, 3 had stage iii, ...

In this article, a fabulous method for database retrieval is proposed.  The multi-resolution modified wavelet transform for each of image is computed and the standard deviation and average are utilized as the textural features. Then, the proposed modified bit-based color histogram and edge detectors were utilized to define the high level features. A feedback-based dynamic weighting of shap...
