3-D body mapping with computer vision
… to map an entire human body in a highly automatic manner. The system consisted of nine CCD cameras arranged in three stereo triples, a 486-based personal computer equipped with two frame grabbers, and three slide projectors for projecting dot patterns on the body. A movable control field …

Pilvinės aortos aneurizmos automatinės detekcijos nauda matuojant aneurizmos tūrį. Literatūros apžvalga ir modelio sukūrimas /
… Despite its widespread use, diameter measurement has some relevant limitations. Therefore, aortic aneurysm volume measurement has recently been reported as a superior and more accurate method than diameter. Although volume measurement excels in detecting aneurysm sac changes …

Detection and description of pulmonary nodules through 2D and 3D clustering
… shape and textures features, classification and automatic measurement of nodule characteristics. This work is tested on standard CT lung image data and shows promising results, matching or close to experts’ diagnosis in the nodules number and their features (size/volume, location) and in terms …

Can non-contact SIAscopy be used in the diagnosis and quantification of pigmentary skin changes associated with photodamage?
… no truly objective method exists which enables automatic measurement of these characteristics without expert evaluation. Methods and results 1140 images of skin of various ages and levels of damage were acquired using standard digital colour photography obtained through crossed polarising …

Video indexing and summarization using motion activity
… psychophysical and analytical framework for automatic measurement of motion activity in compliance with its subjective perception is developed. A psychophysically sound subjective ground truth for motion activity and a test-set of video clips is constructed for this purpose. A number of …

Methodologies for integrating traffic flow theory, ITS and evolving surveillance technologies
… technologies. This integration of theory, measurement and application has been overlooked since the advent of ITS because of the number of disciplines involved. In this context, the following illustrative methodologies are selected, developed and presented in this study: - a methodology for …

An automated tool for measuring human limb bones
… jobs for forensic anthropologists. Multiple measurements must be taken from each bone by hand. 3D scanners are an unfeasible alternative because they are expensive and difficult to transport. This thesis presents a software tool that automatically takes multiple measurements on bones using 2D …
