    • The present invention relates to devices and methods for the measurement and/or for the specification of the perceptual intensity of a visual image, or the perceptual distance between a pair of images. Grayscale test and reference images are processed to produce test and reference luminance images. A luminance filter function is convolved with the reference luminance image to produce a local mean luminance reference image. Test and reference contrast images are produced from the local mean luminance reference image and the test and reference luminance images respectively, followed by application of a contrast sensitivity filter. The resulting images are combined according to mathematical prescriptions to produce a Just Noticeable Difference, JND value, indicative of a Spatial Standard Observer, SSO. Some embodiments include masking functions, window functions, special treatment for images lying on or near borders and pre-processing of test images.
    • 本发明涉及用于测量和/或指定视觉图像的感知强度的装置和方法,或一对图像之间的感知距离。 处理灰度测试和参考图像以产生测试和参考亮度图像。 亮度滤波器功能与参考亮度图像卷积以产生局部平均亮度参考图像。 测试和参考对比度图像分别从本地平均亮度参考图像和测试和参考亮度图像产生,然后应用对比度敏感度滤波器。 所得到的图像根据数学处方结合起来,产生一个“Just Noticeable Difference”,JND值,表示一个空间标准观察者SSO。 一些实施例包括屏蔽功能,窗口功能,位于边界上或附近的图像的特殊处理以及测试图像的预处理。

    • The invention generally relates to methods for sequencing a nucleic acid template from both a 5′ and a 3′ end in a single sequencing reaction. In certain embodiments, methods of the invention involve amplifying a nucleic acid template to produce a plurality of amplicons, splitting the amplicons into first and second portions, attaching a first oligonucleotide including a first universal primer site to a 5′ end of the amplicons in the first portion, and attaching a second oligonucleotide including a second universal primer site to a 3′ end of the amplicons in the second portion. The first and second primer sites may be the same or may be different. The method additionally involves pooling the first and second portions, and sequencing the pooled amplicons, thereby sequencing a nucleic acid template from both a 5′ and a 3′ end in a single sequencing reaction.
    • 本发明一般涉及在单次测序反应中从5'和3'末端测序核酸模板的方法。 在某些实施方案中,本发明的方法包括扩增核酸模板以产生多个扩增子,将扩增子分裂成第一和第二部分,将包含第一通用引物位点的第一寡核苷酸连接到扩增子的5'末端 第一部分,并且在第二部分中将包含第二通用引物位点的第二寡核苷酸连接到扩增子的3'末端。 第一和第二引物位点可以相同或可以不同。 该方法另外涉及合并第一和第二部分,并对合并的扩增子进行测序,从而在单个测序反应中从5'和3'末端测序核酸模板。
