PSNR(Peak Signal to Noise Ratio)是一种评估图像或视频质量的算法,它使用峰值信噪比来度量原始图像和压缩图像之间的差异。PSNR越高,表示压缩图像的质量越好。 PSNR的计算公式如下:
python psnr_value = peak_signal_noise_ratio(image1, image2, data_range=255) image1和image2是需要计算PSNR的两个图像数据。 data_range参数用于指定图像数据的取值范围。对于8位图像,通常取值为255。 获取并处理peak_signal_noise_ratio函数的返回值: peak_signal_noise_ratio函数返回的是一个浮点数,表示两...

The peak-pair file is the output file obtained by running cw-peak-pair python script on the peak call file. The basic operations include calculating a) the mean and median of peak-pair occupancy, b) peak-pair mode, c) Counting the number of orphans, d) Fraction of all mapped reads ...
