  • 基于Contourlet域HMT模型的Cycle Spinning去噪方法

    为了提高图像去噪效果,提出了基于Contourlet域HMT模型的Cycle Spinning去噪方法。首先将待去噪图像进行循环平移,使用Contourlet域HMT模型对平移后的图像进行降噪处理,然后将降噪后的图像进行循环反平移,最后将不同循环平移量下的降噪图像进行平均处理,以减少去噪后图像的失真。实验结果表明,该方法不仅可以提高降噪后 ...

  • 什么时候校准是重要的

    Abstract: Perfection is relative and application specific. The perfect race car is not the car we use to commute to work. We need products for everyday use that are high quality, affordable, and solidly reliable. There will be times when we must use components that are not perfect, and this is when ...

  • 小面积和大面积光电二极管的低噪声放大器

      Photodiodes can be broken into two categories: largearea photodiodes with their attendant high capacitance(30pF to 3000pF) and smaller area photodiodes withrelatively low capacitance (10pF or less). For optimalsignal-to-noise performance, a transimpedance amplifi erconsisting of an invert ...
