Figure 6. Scatter plot of the GOSAT TANSO-FTS XH2O and coincident TCCON soundings (criteria of ±30 min and ±1° in latitude/longitude) at the Lamont (left) and Lauder (right) TCCON sites. All coincidences were found for TANSO-FTS land scans. Figure 4. Scatter plot of the GOSAT TANSO-FTS XH2O and coincident TCCON soundings (criteria of ̆30 min and ̆1 ̋ in latitude/longitude).

Carotid artery disease was assessed in 180 patients by means of color Doppler flow imaging. Color Doppler findings in 360 carotid arteries were compared with the results of standard Doppler sonography, and color Doppler findings in 60 bifurcations were compared with the results of intraarterial angiography. The sensitivity of color Doppler for the detection of carotid disease was 100% when comp...

In this paper, we present a machine vision system that was developed on the basis of neural networks to identify twelve houseplants. Image processing system was used to extract 41 features of color, texture and shape from the images taken from front and back of the leaves. The features were fed into the neural network system as the recognition criteria and inputs. Multilayer perceptron (MLP) ne...

One of the key problems in machine vision is color constancy: the ability to match object colors in images taken under different colors of illumination. This is a difficult problem because the apparent color will depend upon the spectral reflectance function of the object and the spectral distribution function of the incident light, both of which are generally unknown. Methods to solve this pro...

BACKGROUND AND PURPOSE The diagnosis of intracranial atherosclerosis requires availability of appropriate imaging techniques. The objective was to evaluate the proportion of European hospitals where imaging techniques necessary to detect intracranial atherosclerosis are available. Method- We randomly selected 886 hospitals in 25 countries and classified them in 3 categories according to the ava...

We define a sample of 62 galaxies in the Chandra Deep Field-North whose Spitzer IRAC SEDs exhibit the characteristic power-law emission expected of luminous AGN. We study the multiwavelength properties of this sample, and compare the AGN selected in this way to those selected via other Spitzer color-color criteria. Only 55% of the power-law galaxies are detected in the X-ray catalog at exposure...

BACKGROUND An experiment on the relationship between aeromedical color vision screening test performance and performance on color-dependent tasks of Air Traffic Control Specialists (ATCS) was replicated to expand the database supporting the job-related validity of 13 FAA-accepted screening tests. METHODS The original experiment (10) (n = 108), and the replication (n = 136) involved a total of...

1. Definitions: a. Diffusion Tensor Imaging (DTI) refers to the acquisition and reconstruction of MR images with diffusion-encoding gradients applied in a minimum of 6 non-collinear directions, followed by voxel-wise calculation of the tensor representation of a 3D Gaussian model of the diffusion profile and subsequent mapping of any number of tensor parameters. Most commonly these would includ...
