This report describes a two-pass binocular stereo algorithm that is specifically geared towards the detection of depth discontinuities. In the rst pass, introduced in part I of the report, stereo matching is performed independently on each epipolar pair for maximum e ciency. In the second pass, described in part II, disparity information is propagated between the scanlines. Part I. Our stereo a...

Autocorrelation of a double-exposed image, unlike cross-correlation between two images, produces a correlation function that is symmetric about the origin. Thus, while it is possible to calculate the speed and direction of tracer particles in a particle image velocimetry (PIV) image using autocorrelation, it is impossible to tell whether the velocity is in the positive or negative direction. Th...

By today, the technology of synthetic aperture radar (SAR) interferometry (InSAR) has been largely exploited in digital elevation model (DEM) generation and deformation mapping. Conventional InSAR technique exploits two SAR images acquired from slightly different angles, in which the information of elevation and deformation can be captured through processing of the phase difference of the image...

The Landsat and Sentinel series satellites contain their own quality tagging data products, marking the source image pixel by with several specific semantic categories. These products generally categories such as cloud, cloud shadow, land, water body, snow. Due to lack of mid-wave thermal infrared bands, accuracy traditional detection algorithm is unstable when facing Chinese Gaofen-1/6 (GF-1/6...

Multiplex Fluorescence In-Situ Hybridization (M-FISH) is a recently developed chromosome imaging method in which each chromosome is labelled with 5 fluors (dyes) and is also counterstained with DAPI. This paper proposes an automatic pixel by pixel classification algorithm for M-FISH images using a Bayes Classifier. The M-FISH pixel classification was approached as a 25 class 6 feature pattern r...

UNLABELLED CT-based attenuation-corrected (AC) myocardial perfusion imaging (MPI) studies may show significant artifacts caused by misregistration between SPECT and CT data. The present study aimed at identifying the directions and magnitudes of misregistration with greatest impact on AC myocardial perfusion image quality. METHODS The incidence, magnitude, and direction of misregistration wer...
