Mid-Level Vision and Recognition of Non-Rigid Objects

Subirana-Vilanova, J. Brian 01 April 1995 (has links)
We address mid-level vision for the recognition of non-rigid objects. We align model and image using frame curves - which are object or "figure/ground" skeletons. Frame curves are computed, without discontinuities, using Curved Inertia Frames, a provably global scheme implemented on the Connection Machine, based on: non-cartisean networks; a definition of curved axis of inertia; and a ridge detector. I present evidence against frame alignment in human perception. This suggests: frame curves have a role in figure/ground segregation and in fuzzy boundaries; their outside/near/top/ incoming regions are more salient; and that perception begins by setting a reference frame (prior to early vision), and proceeds by processing convex structures.

Visionen & Entreprenören : Framtiden för det framgångsrika entreprenörsföretaget

Morell, Christer, Karlsson, Daniel January 2012 (has links)
Leaders have many tools in their toolbox when it comes to managing their firms, assuring that they are moving in the right direction. One of these tools is vision. Vision can be a powerful tool for steering a company. But to be able to use it fully, you must also understand how vision is best conveyed to employees and followers. If you understand the vision as a tool, you can fully utilize it. Vision is, according to entrepreneurial theory, strongly connected to growth in companies. As more established firms often tend to have highly evolved plans when it comes to the company’s values, we wanted to study the smaller business. And from this our research question evolved. We ask ourselves in this thesis, what effect vision has as a managerial tool in small companies with high growth rates? In the search of our answer we studied Kronfönster, a small, fast growing window manufacturer in the south of Sweden.

Health Related Quality of Life for Children with Cleft Lip and/or Palate

Sinclair, Sandra January 2011 (has links)
A child's health-related quality of life (HRQOL) is a multidimensional, subjective construct that is perceived as a result of the impact that a condition has on the child's physical, emotional, social, and cognitive functioning (WHO, 1995). This study measured HRQOL for a culturally diverse sample of children with cleft lip and/or palate to include parent proxy reports and child self reports. A descriptive quantitative design was utilized. One hundred subjects participated in the study, including 62 parents and 38 children who completed the PedsQL instrument. Results revealed that parents of children with an oral cleft rated their children's Physical Health higher than a normative sample of parents of healthy children which was an unexpected finding. Otherwise, parents of children with an oral cleft and the children themselves rated their Emotional Functioning, Social Functioning, School Functioning, overall Psychosocial Functioning, and Total HRQOL lower than healthy children and higher than children with a chronic condition. Parent-child concordance was quite low in all domains with the highest correlation being only .20 on the Emotional Functioning scale. Demographic variables, speech impairment, and hearing severity did not affect HRQOL scores. Wearing a hearing aid had a significant affect on School Functioning according to the parent's perspective. Overall, the PedsQL was found to be an effective and quick measure of HRQOL for children with an oral cleft that could be utilized during the multidisciplinary cleft clinic to identify children who are at-risk for impaired HRQOL. Since parent-child agreement was low, children should be given every opportunity to rate their own HRQOL. Once individual concerns have been identified, health care providers can then implement care and treatment to maximize the child's satisfaction with health and well-being.
