extremal region detection guided by maxima of gradient magnitude
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Validity of electrical stimulus magnitude matching in chronic pain.
OBJECTIVE To examine the validity of the PainMatcher in chronic pain. DESIGN Comparison of parallel pain estimates from visual analogue scales with electrical stimulus magnitude matching. PATIENTS Thirty-one patients with chronic musculoskeletal pain. METHODS Twice a day ongoing pain was rated on a standard 100-mm visual analogue scale, and thereafter magnitude matching was performed usin...
متن کاملIdentification of Hammerstein and Wiener Models Using Spectral Magnitude Matching
The problem of the identification of Hammerstein and Wiener models is considered in this paper. The suggested approach in this paper utilizes the spectral magnitude matching method that minimizes the sum squared error between the spectral magnitudes evaluated for a number of short-time frames of the measured output signal of the nonlinear system and the output signal of the nonlinear model. The...
متن کاملComparing spontaneous cross-modal magnitude matching in infants and adults
It has been proposed that young infants, in contrast to adults, base similarities in stimuli across modalities on quantitative aspects rather than on qualitative aspects. To investigate the spontaneous quantitative matching across modalities in adults and infants, 12 adults and 32 infants watched film sequences while their looking behavior was recorded using an eye-tracker. The film sequences d...
متن کاملImproving Integrity and Reliability of Map Matching Techniques
Map-matching (MM) is a technique that attempts to locate an estimated vehicle position on road network. Many map-matching algorithms have been developed and widely incorporated into GPS/DR vehicle navigation systems for both commercial and experimental ITS applications. However, the reliability of these systems is still a problem because vehicle position may be located to an incorrect road sect...
