The imaging measurement system must be calibrated before application. In calibration procedure
sub-pixel center extraction is the crucial step for the final accuracy. In this paper
a new sub-pixel extraction method is proposed. Edge detection at pixel level is obtained using LOG operator
then sub-pixel edge detection is realized using the Facet model. Finally
the least squares ellipse fitting is operated on the sub-pixel edge to determine the sub-pixel center. Experiment on a series of simulated images indicates that this algorithm is able to realize the center location accuracy of 0.01-0.02 pixel
and meets the requirement of sub-pixel level. (2012) Trans Tech Publications

In range measurement
theodolite and radar constitute a real-time tracking system at different sites to track the same target in the air and get useful information exactly and timely. As the optical theodolite and radar have different sampling frequency and measurement system
the data is sent to the fusion center is asynchronous. This paper proposed a time registration method based on multi-sensor data using Wavelet neural network algorithm
which not only better solved the basic problems of theodolite fusion tracking but also improve the efficiency of data fusion. Simulation experiment and comparison with other time registration method have shown the advantage of this method. 2012 IEEE.

A set of ZnO films of different thickness have been deposited on sapphire substrates using molecular beam epitaxy (MBE) by varying the growth time and the effect of film thickness on the structural
electrical and optical properties have been investigated. The X-ray diffraction (XRD) results indicate that the full width at half maximum (FWHM) of the (002) diffraction peak is decreased as the film thickness increasing
and the stress along c-axis is stable. Scanning electron microscope (SEM) measurement shows that the grains become more uniform as the film grows thicker and the film surface present distinct hexagon shape as the film is grown up to a thickness of 500nm. The optical absorbance
Hall mobility and photoluminescence (PL) intensity are increased in accordance with the thickness of the film. (2011) Trans Tech Publications

In order to detect the corners of the teeth image
secondly
last we detected the corners of the image through the improved SUSAN corner detector algorithm. Through lots of experiments and comparing with other corner detector methods
which were acquired by oral cavity endoscope
we segmented the image by the threshold based on the gray value of the image
this method can detect the corners of the teeth image effectively
in this paper
which can offer some available parameters for the 3D reconstruction of the teeth. 2010 IEEE.
we used the improved SUSAN corner detector algorithm. In this method
firstly
we removed the noise of the image by the morphology open operation and median filtering

In order to meet requirement of real-time and high accuracy in image matching aided navigation
SSDA algorithm is used to match remote sensing image and template image coarsely
a fast and effective algorithm of remote sensing image matching based on corner detection is put forward. With the combination of rough and fine match
when the matching result is bigger than one to count absolute value sum of energy difference of characteristic point energy to realize fine match of remote sensing image and template image to locate the position of template image in remote sensing image accurately. Simulation experiment proves that the matching of a remote sensing image resolution of 1018*1530 and a template image resolution of 150*90 can be fulfilled within 2.392 second
wavelet transform is used to acquire low frequency component to realize image compression to decrease calculation work and increase matching speed. Harris corner detection algorithm is used to detect corner of remote sensing image and template image and energy of every corner is calculated
the algorithm is robust and effective
real time image navigation can be achieved. 2009 SPIE.
