We propose an approach for improving the digitization of shape and color 3D artworks in a cluttered environment using laser scanning flash photography. To separate clutter from acquired material, semiautomated methods are employed to generate masks used segment range maps photographs. This allows removal unwanted data prior integration model. Sharp shadows generated by acquisition easily handled this masking process, deviations introduced light corrected at blending step taking into account...

Background: People bereaved by suicide often face isolation, complicated grief, and increased risk. Aims: We aimed to explore how live-chat can support survivors in their bereavement process. Method: A thematic analysis was carried out on 30 conversations through the software ATLAS.ti8. Transcripts were retrieved from a major Italian association providing online support. The users had different ages (18-60 years), degrees of kinship with deceased (blood-related not), time distance loss...
