FSIM(Feature Similarity,特征相似性)这是用于计算图片质量或者对比两张图片相似性的一个评价参数,相比于PSNR(峰值信噪比)、SSIM(结构相似性)这个两个广泛使用的图像质量评价参数,FSIM更能体现图片之间的差异性,是一个很先进的图片质量评价参数。本资源包含了两份代码,一份是matlab代码,一份是python代码,用户可以根据自...

Structural similarity index (SSIM) 1 Introduction A rapid advancement in sensor technology has improved medical prognosis, surgical navigation and treatment. For example, anatomical modalities such as Magnetic resonance imaging (MRI) and Computed Tomography (CT) reveals the structural information of the ...

Protein structure strongly dictates function, with minimal changes often dramatically affecting major properties1, localization2, binding partners3, and structure stability4. Protein tertiary structure can be up to ten times more conserved than genomic sequence5and can reveal a greater genomic similarity....
Exploiting sequence–structure–function relationships in biotechnology requires improved methods for aligning proteins that have low sequence similarity to previously annotated proteins. We develop two deep learning methods to address this gap, TM-Vec and DeepBLAST. TM-Vec allows searching for structure–...

Assortativity coefficient: a measure of similarity of connections within the graph with respect to the degree - this produces a value between -1 {not at all similar} and +1 {very similar}. A value near zero represents randomly distributed connections. Reported as: value, width-weighted counterpa...
