Abstract According to the surface reflection characteristics of carbon fiber reinforced plastics and geometric aircraft panel parts, a robot automatic measurement system based on line laser scanning is designed. The selection criteria pose pre-calibration method tracker are given. A 3D reconstruction global stitching large-scale parts proposed, Finally, correctness effectiveness proposed verifi...

OBJECTIVE Sub-standard quality in X-ray image acquisition and interpretation is common in low-resource countries, and can ultimately result in higher patient morbidity and mortality. This study aimed at evaluating; 1) feasibility of implementing a digital X-ray device in a second level hospital in Angola; 2) quality of digital X-ray images, when digital radiology was in the hands of local techn...

This paper introduces a method of image recognition based on the gradual generating and analysis of data structure consisting of the 2D space using the difference from the row and column vectors’ sums as an application of the linear algebra. The result of the data processing is a graphical interpretation of the measure of the similarity of the generated results of overlapping of 2 images. Maxim...

Transmission electron microscopy (TEM) provides extremely detailed high-resolution images of biological structures ranging from subcellular organelles to whole tissues. An advantage of this approach is that TEM allows simultaneous visualization of many different cellular components, providing a holistic view of a cell or tissue, in contrast to fluorescence microscopy which provides spatial info...

background: a method to track liver tumor motion signals from fluoroscopic images without any implanted gold fiducial markers was proposed in this study to overcome the adverse effects on precise tumor irradiation caused by respiratory movement. materials and methods: the method was based on the following idea: (i) before treatment, a series of fluoroscopic images corresponding to different bre...

A dual-band infrared camera system based on a dual-band quantum well infrared photodetector (QWIP) has been developed for acquiring images from both the mid-wavelength (MWIR) and long-wavelength (LWIR) infrared spectral band. The system delivers exactly pixel-registered simultaneously acquired images. It has the advantage that appropriate signal and image processing permit to exploit difference...

introduction: in this study, a computer analysis method based on a block matching algorithm is presented to extract the longitudinal movement of the carotid artery wall using consecutive ultrasonic images. a window (block) is selected as the reference block in the first frame and the most similar block to the reference one is found in the subsequent frames. material and methods: the program was...

We present an integrated system for the automatic analysis of MRI-breast images for the early detection of breast cancer. MAM-MALYZER II is developed in cooperation with Dr. Buddenbrock, Dr Blasinger, Dr. Benz hospital for Radiology and Nuclear Medicine, Mainz. The system operates on taken images using the method of dynamic contrast-enhanced MRI. Suspicious lesions in the breast are automatical...
