给定three-dimensional numpy数组,可以使用numpy.argmax计算第一维度(轴0)上最大值的索引。 如何使用argmax的结果从另一个形状相似的数组中提取所述最大值? 例如,给定以下内容: import numpy as np ndarr1 = np.round(np.random.rand(4, 2, 3), 2) ndarr2 = np.round(np.random.rand(4, 2, 3), ...
import numpy as np import scipy img = np.random.rand(64, 64, 54) #three dimensional image k1 = np.array([0.114, 0.141, 0.161, 0.168, 0.161, 0.141, 0.114]) #the kernel along the 1st dimension k2 = k1 #the kernel along the 2nd dimension k3 = k1 #the kernel along the 3nd ...

X-ray computed tomography (CT) allows us to visualize root system architecture (RSA) beneath the soil, non-destructively and in a three-dimensional (3-D) form. However, CT scanning, reconstruction processes, and root isolation from X-ray CT volumes, take considerable time. For genetic analyses...
Theano does not natively support any particular file format or database, but as previously stated, can use anything as long as it is read in as an N-dimensional array. While far from comprehensive, this hopefully gives you a feel for the LMDB/HDF5 integration by some key deep learning libr...
Welcome to use this small program for drawing three-dimensional Bulk and Surface Brillouin Zones. Directly download the Jupyter notebook/Python file and use it! Require numpy and matplotlib Class: BZ Initial input: Vectors of bulk Brillouin zone, with unit A^-1 and written in the Cartesian coo...
I wish to fill all zero valued elements of a three-dimensional numpy array with the value of the "nearest" non-zero valued element (at the point of running the program.) I do not mind which is used when there are multiple with the same distance. ...
1.2. Three-Dimensional Technologies in Plant Phenotyping Over the past thirty years, advancements in capturing three-dimensional (3D) surface information from plants have revolutionized our understanding of plant architecture and growth [15,16,17]. The utilization of 3D measurement technologies provides ...
Three-dimensional printing, specifically fused deposition modeling (FDM), is a standard for prototyping and small-scale custom plastics production because of its low cost and ability for rapid iteration. However, little information exists about whether FDM-printed thermoplastics affect measurements of ...
