Color space is the basis of color image processing. Under normal circumstances, there are two kinds of color description: RGB color space and YCbCr color space. In the video process, normally the obtained and displayed colors are described by RGB. YCbCr color space is introduced to reduce the bandwidth and information storage. Selection of color space(More)
In this paper, CN-DPA was prepared as an effective colorimetric and fluorescent probe for copper ions (Cu(2+)) in aqueous solution. It exhibits good sensitivity and selectivity for Cu(2+) over other metal ions both in aqueous solution and on a simple colorimetric paper-made test kit. Upon addition of Cu(2+), a remarkable color change from purple to(More)
To investigate the magnetic resonance imaging (MRI) features of spinal cord decompression sickness (DCS) on compressed-air divers, we hereby report seven cases diagnosed with spinal cord DCS. Only two patients out of seven showed positive MRI findings: A detailed case report will be provided on each. In one of the cases, the MRI revealed extensive high(More)
The surface of the object is continuous and smooth. As one of the most popular methods, polygon meshes are extensively used in computer graphics. But it is difficult to achieve the sparse representation of polygon based 3D model due to its raw and discrete characters. Thus, the compressive sensing based compression method cannot be applied on 3D model(More)
We propose connectivity-preserving geometry images (CGIMs), which map a triangular mesh onto a rectangular regular array of an image, such that the reconstructed mesh produces no sampling errors, but merely round-off errors over the coordinates of vertices. Using permutation techniques on vertices, CGIMs first obtain a V-matrix whose elements are vertices(More)
Carbon monoxide (CO), as a product of incomplete combustion of organic substances due to insufficient oxygen to enable complete oxidation to carbon dioxide (CO 2), is toxic but colorless, odorless, tasteless, and initially non-irritating. CO poisoning occurs after prolonged exposure with a potentially lethal dosage over 100 ppm(1). It is such an common and(More)
