Calibration of high-speed imaging by laser triangulation
Logopedics Phoniatrics Vocology, 2004A method was developed for absolute calibration of endoscopic vocal fold images using laser triangulation. The laser is attached to a rigid endoscope with 8-degrees angle in relation to the optical axis of the endoscope. A special software is used for calibration and measurements from high-speed images.

A high-speed image centroid computation sensor
2012 IEEE 55th International Midwest Symposium on Circuits and Systems (MWSCAS), 2012We present a fully-integrated analog CMOS image centroid computation sensor. A 40×40 pixel array is designed and fabricated in a 0.5-µm CMOS process. The proposed centroid computation circuit achieves 7 times improvement in bandwidth compared to similar circuits in the literature.

A high speed maximum entropy encoder for images
ICASSP '83. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005A simple nonlinear memory based coding system is presented which encodes and decodes images rapidly. The nonlinear nature of the coding system allows edges to be represented well. The coding system compares favorably to predictive coders in the one to two bits per pixel range.

Drop hammer with high-speed thermal imaging
Review of Scientific Instruments, 2018The drop hammer test is the easiest way to assess the sensitivity of explosive materials, but drop hammer results for low-velocity impacts have not been able to explain how explosives will react to other kinds of initiating stimuli. In order to do that, we have to understand the fundamental mechanisms of drop hammer initiation and how they differ from ...

High Speed Imaging of the Heart
1988Magnetic resonance (MR) imaging has thus far demonstrated enormous capability for visualization of the normal and pathologic heart (1 – 9). MR has accurately defined normal cardiac anatomy (1), congenital cardiac abnormalities (2), acute myocardial infarction (3), chronic myocardial infarction (4), myocardial ischemia (5), cardiac and paracardiac ...

High Speed Image Rotation in Embedded Systems
Computer Vision and Image Understanding, 1995Abstract The design of an enhanced SIMD processor, named the SIMDDE, is evaluated. The architecture has circular data paths, as well as row and column paths. The SIMDDE architecture is intended primarily for use in image recognition in embedded systems.

High speed imaging polarimeter
2012We have implemented a portable high-speed imaging polarimeter using a single ferroelectric liquid crystal cell. The originality of this work lies in the fact that we do not work at the nominal wavelength of the cell. Consequently we obtain the full polarimetric information (i.e. the Stokes vector) with only one modulator.
