Conventional active sonar processing systems typically reduce the sensor data from an intensity map to a pointmeasurement form via a detection thresholding process. This approach is often sufficient for detecting and tracking high signal-to-noise-ratio (SNR) targets but becomes more challenging for low SNR targets. Track-Before-Detect (TkBD) is an alternative tracking technique that supplies ra...

When sensory receptors are stimulated, a series of negative and positive deflections time-locked to stimulus onset may be evoked in the electroencephalogram (EEG). Since these potentials are evoked by sensory stimulation, they are called sensory-evoked potentials (EPs). Because of the small magnitude of the EP in relation to ongoing background noise, many stimulus trials must be averaged to obt...

Line following robots are applied in numerous application areas. High reliability of the line estimation could be obtained by the application of Track–Before–Detect algorithms, like Viterbi algorithm. The hardware and software of the robot are shown in the paper. Real–time constraint are discussed in this paper, related to the constructed robot. The obtained results shows the possibilities of t...

An effective algorithm for the detection of dim-small moving target in the infrared (IR) image sequence is described in this paper, which is based on the idea of Track-Before-Detect (TBD). To deal with the low signal to noise ratio (SNR) and high false alarm rate of the IR target detection in the sky scene, two of the Track-Before-Detect (TBD) methods are introduced: dynamic programming (DP) fo...

In many remote sensing applications, the area of a scene sensed by a single pixel can often be measured in square meters. This means that many objects of interest in a scene are smaller than a single pixel in the resulting image. Current tracking methods rely on robust object detection using multi-pixel features. A subpixel object does not provide enough information for these methods to work. T...

The track-before-detect (TBD) methodologies jointly process more consecutive scans and show superior detection performance for the low signal-to-noise ratio (SNR) targets over the conventional methods. A TBD algorithm based on improved Randomized Hough Transform for dim target detection is proposed in this paper. This algorithm uses the sequence numbers of scans to make sure that the point pair...

Although, most of the abnormal structures of human brain do not alter the shape of outer envelope of brain (surface), some abnormalities can deform the surface extensively. However, this may be a major problem in a surface-based registration technique, since two nearly identical surfaces are required for surface fitting process. A type of verification known as the circularity check for th...
