| This paper presents an overview of feature extraction methods for oo-line recognition of segmented (isolated) characters. Selection of a feature extraction method is probably the single most important factor in achieving high recognition performance in character recognition systems. Diierent feature extraction methods are designed for diierent… (More)
The size of motor units has been measured in adult rat muscles reinnervated by active and inactive motor axons. The results suggest that active nerve terminals have a competitive advantage over inactive terminals during neuromuscular synapse elimination. The experiments were done using the fourth deep lumbrical muscle in the rat hind foot, which receives… (More)
1. Polyneuronal innervation of normal and reinnervated fourth deep lumbrical muscle fibres was studied with tension measurements and intracellular recordings. From the tenth day after a complete crush of the muscle nerve, some of the reinnervated muscles were completely paralysed for up to 15 days by local application of tetrodotoxin (TTX) to the sciatic… (More)
The fourth deep lumbrical muscle in the hind foot of adult rats was partially denervated by crushing the sural nerve (s.n.). The denervated muscle fibres became completely reinnervated by sprouts from lateral plantar nerve (l.p.n.) motor axons. By about 20 days after the nerve crush, s.n. motor axons started to reinnervate the muscle. In control muscles, a… (More)
Absfracf-Several methods for segmentation of document images are explored. We pose the segmentation operation as a statistical classification task with two pattern classes: print and background. A number of classification strategies are available. All require some prior information about the distribution of gray levels for the two classes. Training (either… (More)
In this paper, White and Rohrer's \Integrated Function Algorithm" (1983) for binarization of gray level document images is improved. This is achieved by smoothing, a new print pixel identiication strategy, and a postprocessing step removing false print objects.
Multipass dynamic MRI and pharmacokinetic modeling are used to estimate perfusion parameters of leaky capillaries. Curve fitting and nonblind deconvolution are the established methods to derive the perfusion estimates from the observed arterial input function (AIF) and tissue tracer concentration function. These nonblind methods are sensitive to errors in… (More)
