This paper proposes an efficient technique for human motion recognition based on motion history images and an eigenspace technique. In recent years, human motion recognition has become one of the most popular research fields. It is expected to be applied in a security system, man-machine communication, and so on. In the proposed technique, we use two feature images and the eigenspace technique ...

Objective: The aim of the study was to evaluate the clinical value of the video colposcopy in screening cervical intraepithelial neoplasia (CIN) in cytological negative and smooth cervices by optically gynecological examination. Methods: The 1050 women, whose cervices had been shown smooth and cytological negative by optical examine, were examined with electronic colposcopy in gynecological cli...

OBJECTIVE To compare the prevalence and type of human papillomavirus (HPV) infections in the genital tract of human-immunodeficiency-virus- (HIV) seropositive and -seronegative women matched for cytology and to examine prospectively the relationship of HPV DNA, colposcopic findings and cervical squamous intraepithelial lesions (SIL) in these matched seropositive and seronegative cohorts. METH...

INTRODUCTION Cervical cancer develops from well-defined precursor lesions in a varied period of time. Detected in early or pre-invasive stages, cervical cancer is preventable and curable, so detection of precancerous lesions is very important. Colposcopy with directed biopsy is used in the evaluation and management of patients with cervical lesions, and described as the 'gold standard' for the ...

Abnormal looking cervix, or suspicious cervix, is a common clinical condition seen in gynecological practice. Colposcopic examination of the cervix allows differentiation between physiologic changes that occur in response to normal cyclic variations in hormone secretion and a variety of structural and pathological conditions. This article addresses some of these common clinical problems and pro...

OBJECTIVE To determine if electrical impedance spectroscopy (EIS) improves the diagnostic accuracy of colposcopy when used as an adjunct. DESIGN Prospective, comparative, multi-centre clinical study. SETTING Three colposcopy clinics: two in England and one in Ireland. POPULATION Women referred with abnormal cytology. METHODS In phase 1, EIS was assessed against colposcopic impression an...

The laser is a new tool which can be a precise and accurate instrument for tissue removal under colposcopic direction in the areas of the cervix, vagina and vulva. Healing is rapid since the laser inflicts minimal tissue destruction. Postoperative pain is minimal and healing is without scar formation. The expense of the equipment and training of the operating surgeon are its only drawbacks.
