ndpatch 0.0.2

安装

安装最新版本的最简单方法是使用pip:

$ pip install ndpatch

您还可以使用git克隆存储库并手动安装：

$ git clone https://github.com/ashkarin/ndpatch.git
$ cd ndpatch
$ python setup.py install

用法

从阵列中获取修补程序：

importnumpyasnpimportndpatcharray=np.arange(25).reshape((5,5))index=(1,2)shape=(3,3)patch=ndpatch.get_ndpatch(array,shape,index)# patch =# [[ 7,  8,  9],#  [12, 13, 14],#  [17, 18, 19]]

获取随机补丁索引：

importnumpyasnpimportndpatcharray_shape=(5,5)index=ndpatch.get_random_patch_index(array_shape)

从阵列中提取随机补丁：

importnumpyasnpimportndpatchnpatches=10patch_shape=(3,3)array=np.arange(100).reshape((10,10))patches=[ndpatch.get_random_ndpatch(array,patch_shape)for_inrange(npatches)]

要在一组重叠的三维面片上拆分三维阵列并将其重新生成，请执行以下操作：

importnumpyasnpimportndpatcharray=np.arange(0,125).reshape((5,5,5))patch_shape=(4,3,3)overlap=2indices=ndpatch.get_patches_indices(array.shape,patch_shape,overlap)patches=[ndpatch.get_ndpatch(array,patch_shape,index)forindexinindices]reconstructed=ndpatch.reconstruct_from_patches(patches,indices,array.shape,default_value=0)# Validateequal=(reconstructed==array)assert(np.all(equal))
