A novel approach to background/foreground segmentation using an online EM algorithm is presented. The method models each layer as a Gaussian mixture, with local, per pixel, parameters for the background layer and global parameters for the foreground layer, utilising information from the entire scene when estimating the foreground. Additionally, the online EM algorithm uses a progressive learning r

Popular Abstract in Swedish Signaler om smärta och känsel löper från receptorer ute i kroppen genom olika typer av nervfibrer in till ryggmärgens bakhorn och till trigeminuskärnorna i hjärnstammen. Där kopplas signalerna via synapser vidare till nervceller som leder signalerna upp till hjärnan, så att vi blir medvetna om vad som händer i kroppen. På sin väg till hjärnbarken kopplas signalerna om yThe amino acid glutamate is today regarded as the main fast excitatory neurotransmitter in the central nervous system and a large body of evidence support that glutamate serves as a neurotransmitter in primary afferent terminals in the spinal cord. Previous evidence also suggests that the closely related amino acid aspartate may serve a similar role in some primary afferent terminals. However, the

In a small perception study, our ability to estimate speaker age from speech samples was investigated with respect to stimulus duration, stimulus type and speaker gender. Four separate listening tests were carried out with four different sets of stimuli: 10 and 3 seconds of spontaneous speech, one isolated word, and 6 concatenated isolated words, all produced by the same 24 speakers. The results s

Popular Abstract in Swedish Höftfraktur är ett av de vanligaste benbrotten hos äldre. Var tredje säng på en ortopedklinik upptas av en patient med denna skada. Under de senaste decennierna har antalet höftfrakturer i Sverige fördubblats. Denna ökning beror dels på en större andel äldre i befolkningen och dels på en ökad risk för den enskilde åldringen att få en höftfraktur. Idag beräknas antalet hIn stabilising extracapsular hip fractures, the Medoff sliding plate (MSP) differs from other screw-plates by its compression capacity along the femoral shaft (uniaxial dynamization). Additional compression along the neck of femur can be achieved by primary release of the lag screw (biaxial dynamization). 244 consecutive inter- and subtrochanteric fractures in 243 elderly patients were fixed with
