Measurement of meningeal blood vessel diameter in vivo with a plug-in for ImageJ
TL;DR: An approach with a CCD camera for image acquisition combined with free and open source ImageJ software for offline analysis allows the user to quickly evaluate vessel diameter changes in the whole acquired field at any selected position.

Automatic extraction and measurement of leukocyte motion in microvessels using spatiotemporal image analysis
Yoshinobu Sato,Jian Chen,Reza Aghaeizadeh Zoroofi,Noboru Harada,Shinichi Tamura,Takeshi Shiga +5 more
TL;DR: This paper describes a computer vision system for the automatic extraction and velocity measurement of moving leukocytes that adhere to microvessel walls from a sequence of images and shows experimentally that the proposed method can stably extract leukocyte motion.

Detection of leukocytes in contact with the vessel wall from in vivo microscope recordings using a neural network
Michael Egmont-Petersen,U. Schreiner,S. C. Tromp,Thomas Martin Lehmann,Dick W. Slaaf,Theo Arts +5 more
TL;DR: Experiments indicate that neural networks trained with the synthetic leukocyte images perform better than networks training with images of manually detected leukocytes.
Journal ArticleDOI
In‐vivo analysis of angiogenesis and revascularization of transplanted pancreatic islets using confocal microscopy
TL;DR: In‐vivo imaging of the microcirculation of transplanted pancreatic islets was conducted using a confocal scanning laser microscope (CSLM) to achieve optical sectioning through the graft in order to perform a computer reconstruction of the three‐dimensional neovascular morphology.

On edge detection
V. Torre,Tomaso Poggio +1 more
TL;DR: It is shown that numerical differentiation of images is an ill-posed problem in the sense of Hadamard, and that this part of edge detection consists of two steps, a filtering step and a differentiation step.

Structure from stereo-a review
U.R. Dhond,Jake K. Aggarwal +1 more
TL;DR: Broad categories of stereo algorithms are identified on the basis of differences in imaging geometry, matching primitives, and the computational structure used for the extraction of the 3D structure of a scene.

On Edge Detection
V. Torre,Tomaso Poggio +1 more
TL;DR: In this paper, the authors consider the edge detection problem as a numerical differentiation problem and show that numerical differentiation of images is an ill-posed problem in the sense of Hadamard.

Quantitative design and evaluation of enhancement/thresholding edge detectors
I.E. Abdou,W.K. Pratt +1 more
TL;DR: Theoretical and experimental comparisons of edge detectors are presented and quantitative design and performance evaluation techniques developed are used to optimally design a variety of small and large mask edge detectors.

Detection of Intensity Changes with Subpixel Accuracy Using Laplacian-Gaussian Masks
A. Huertas,Gerard Medioni +1 more
TL;DR: A system that takes a gray level image as input, locates edges with subpixel accuracy, and links them into lines and notes that the zero-crossings obtained from the full resolution image using a space constant ¿ for the Gaussian, are very similar, but the processing times are very different.
