1) image contrast 图像对比度1. The weak but useful signal limits the OCT imaging speed,detection sensitivity,signal-to-noise ratio and image contrast. 仿真结果:表明对OCT成像有贡献的背向散射光强是样品臂入射光强的10-8~10-10,这样微弱的有用信号限制OCT系统的成像速度、探测灵敏度、信噪比和图像对比...
4.得到ratio图,利用Image Calculator计算两张图的比值:Process ->Image Calculator ->Divide ,32-bit(foat)result ->ok。 5.添加伪彩: Image -> Lookup Tables ->Blue ->Invert LUT 调整成为 这里添加Spectrum样式的伪彩,可以适当调节对比度(Image -> Adjust -> Brightness/Contrast),也可以不用。 6.生成Ca...
PAT-GEOM的主要功能是图形的量化分析。该插件可以测量了7种图案特征: 形状(Shape) 形状方向性(Shape directionality)——横纵比和长轴角度 尺寸(Size)——形心 对比度(Pattern contrast )——均方根对比度 分布(Distribution) 分布方向性(Distribution directionality)——角度和R2值 形状随机性(Pattern randomness)—...
Image Contrast I know long TR/TE gives T2-weighting and short TR/TE gives T1-weighting, but I don't understand why. Can you explain? On spin-echo (SE) imaging,the repetition time (TR)and theecho time (TE)are used to control image contrast and the "weighting" of the MR image. Ther...

论文《A New Hardware-Efficient Algorithm and Reconfigurable Architecture for Image Contrast Enhancement》提到对对比度增强的图像进行客观评价,引用论文《Image Enhancement for Back
A low interest image may also contain uniform texture, as well as, uniform color or low contrast. Perceptual features for individual video frames were computed using common textual features such as, coarseness, contrast, directionality, and regularity. For more details on texture analysis, please ...
The contrast-to-noise ratio (CNR) is presented and characterized as a tool for quantitative noise measurement of scanning electron microscope (SEM) images. Analogies as well as differences between the CNR and the widely used signal-to-noise ratio (SNR) are analytically and experimentally investigate...
