    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer vision; low-level processing; scale-space; diffusion; Gaussian filtering; discrete smoothing; primal sketch; segmentation; descriptive elements; scale detection; image structure; focus-of-attention; tuning low-level processing; blob detection; edge detection; edge focusing; histogram analysis; junction classification; perceptual grouping; texture analysis; critical points; classification of blob events; bifurcations; drift velocity; density of local extrema; multi-scale representation; digital signal processing; Computer Science; Datalogi;

    Abstract : This thesis, within the subfield of computer science known as computer vision, deals with the use of scale-space analysis in early low-level processing of visual information. The main contributions comprise the following five subjects:The formulation of a scale-space theory for discrete signals. READ MORE

  4. 2. A first sketch of Computer Aided Ideation : Exploring CAD tools as externalization media in design ideation

    Author : Philip Ekströmer; Renee Wever; Johan Ölvander; Peter Törlind; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Even though Computer Aided Design (CAD) tools have changed the way designers work in most parts of the design process, designers still mostly use pen-and-paper sketching when generating design ideas. Previous studies exploring the use of CAD tools for design ideation have concluded that the tools available at the time did not support reflective conversation, serendipitous interpretation and creativity, making them unsuited for design ideation.

  5. 3. Helping robots help us : Using prior information for localization, navigation, and human-robot interaction

    Author : Malcolm Mielle; Martin Magnusson; Achim Lilienthal; Erik Schaffernicht; Marjorie Skubic; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; graph-based SLAM; prior map; sketch map; emergency map; map matching; graph matching; segmentation; search and rescue;

    Abstract : Maps are often used to provide information and guide people. Emergency maps or floor plans are often displayed on walls and sketch maps can easily be drawn to give directions. However, robots typically assume that no knowledge of the environment is available before exploration even though making use of prior maps could enhance robotic mapping. READ MORE

  7. 5. ”Sketch and Talk”, Drawing lines between incarcerated humans, the interior, and “stuff”. Design methodologies for (well)-being in prisons, youth homes and psychiatric hospitals

    Author : Franz James; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; Design methods; Design methodology; Field drawing; Ethnographic drawing; Carceral design; Prison design; Youth homes; Forensic psychiatric hospitals; Sketching;

    Abstract : With increasing global and local incarceration, the demand for prison beds is rapidly growing. The Swedish government’s plans for implementing youth prisons and amending laws regarding young people’s sentences risk increasing the already high numbers of mental health problems. READ MORE
