Many software packages include background subtraction algorithms to enhance the contrast of features in the image by reducing background noise. The most common methods used to remove background noise…

清晰对比、无雾的 3D 样本实时图像

历史上，宽场显微镜并不适合对大样本/标本体积进行成像。图像背景（BG）主要来源于观察样本的失焦区域，显著降低了成像系统的对比度、有效动态范围和最大可能的信噪比（SNR）。记录的图像显示出典型的雾霭，并且在许多情况下，无法提供进一步分析所需的细节水平。处理厚三维样本的研究人员要么使用替代显微镜方法，要么尝试通过后处理一系列图像来减少雾霭。
