本文将介绍如何通过Python中的WriteArray功能将矩阵存储为TIFF影像。 1. 环境准备 首先确保您已经安装了必要的 Python 库。通常,我们使用numpy来生成矩阵,并使用tifffile或imageio等库来存储TIFF文件。可以通过以下命令安装这些库: pipinstallnumpy tifffile 1. 2. 生成矩阵 我们可以使用
The imread method returns a NumPy array, img, that contains the image pixel values. We can check out the array’s data type and dimensions as follows: 1 print('Datatype:', img.dtype, '\nDimensions:', img.shape) 1 2 Datatype: uint8 Dimensions: (4000, 6000, 3) The returned...
Read the whole image stack from the multi-page TIFF file as NumPy array:>>> image_stack = imread('temp.tif') >>> image_stack.shape (64, 301, 219) >>> image_stack.dtype dtype('uint16')Read the image from the first page in the TIFF file as NumPy array:>>> image = imread('...

大致流程,从图片中获取隐藏的数据,对应到-max_lim-max_lim域而后与短时傅里叶变换后的音频数据进行比较,整体求范数,最后<3.0则通过验证傅里叶变换后的数据可以直接通过image_to_array可以拿到,我们需要对数据求逆获得原始音频数据而后利用librosa.output.write_wav保存输出,首先想到的是librosa原生求短时傅里叶函数is...
