OBJECTIVE To evaluate the reproducibility of the calculation of breast density with DM-Scan software, which is based on the semiautomatic segmentation of fibroglandular tissue, and to compare it with the reproducibility of estimation by visual inspection. MATERIAL AND METHODS The study included 655 direct digital mammograms acquired using craniocaudal projections. Three experienced radiologis...

OBJECTIVE To assess the sensitivity and specificity of visual inspection of cervix for detection of precancerous and early cancerous lesions of cervix. METHODS In a Maternal and Child Health Care setting of New Delhi women underwent a detailed pelvic examination, visual inspection of cervix after 5% acetic acid application, cytology (pap smear), detailed colposcopic examination and colposcopi...

This study was carried out to evaluate in situ the influence of microleakage, surface roughness and biofilm control on caries formation around composite resin restorations. During 28 days, 12 volunteers wore palatal devices containing bovine enamel slabs restored with composite resin. Restorations were made without leakage, when the adhesive system was applied, or with leakage, when adhesive sy...

In this paper we present a novelty detection mechanism in which a mobile robot learns a model for its environment through visual exploration. Once the learning process is finished, the robot can be used to inspect the environment and highlight stimuli that do not fit the acquired model of normality. Experimental results from a visual inspection task involving the detection of arbitrary objects ...

Mobile robot applications that involve automated exploration and inspection of environments are often dependant on novelty detection, the ability to differentiate between common and uncommon perceptions. Because novelty can be anything that deviates from the normal context, we argue that in order to implement a novelty filter it is necessary to exploit the robot’s sensory data from the ground u...
