A tumor could be found in any area of the brain and could be of any size, shape, and
contrast. There may exist multiple tumors of different types in a human brain at the same …

The measurement of static vertical deflections on bridges continues to be a first-level
technological challenge. These data are of great interest, especially for the case of long-term …

The star tracker is one of the most promising attitude measurement devices used in
spacecraft due to its extremely high accuracy. However, high dynamic performance is still …

The precision of star point location is significant to identify the star map and to acquire the
aircraft attitude for star sensors. Under dynamic conditions, star images are not only …

The proton beam is an important population of the non-Maxwellian proton velocity
distribution in the solar wind, but its role in wave activity remains unclear. In particular, the …

Subpixel centroid estimation is the most important star image location method of star tracker.
This paper presents a theoretical analysis of the systematic error of subpixel centroid …

The high-precise star sensor calibration method requires high-accurate turntable, collimator,
star point plate or other high-precision devices that are very expensive. We present a simple …

The small imaging size of targets over long distances results in the loss of geometry and
spatial features. Current methods are subject to sampling limitations and cannot accurately …

Eye-in-hand robotic binocular sensor systems are indispensable equipment in the modern
manufacturing industry. However, because of the intrinsic deficiencies of the binocular …

We propose a unique dataset with star images, their centroids, and a new centroid algorithm
based on machine learning, that significantly improves star image centroid performance …
