Outer product uvT output: matrix time complexity: O(n2) Inner product uTv output: scalar time complexity: O(n) a = [a0, a1, a2, ... , aN-1], b = [b0, b1, b2, ...., bN-1] a0*b0 + a1*b1 + aN-1*bN-1 Assuming that multiplication and addition are constant-time operations, the time-complexity is O(n) Multiply O(n) + add O(n) = O(n)

When to Resample? Anytime we use two datasets with different sized voxels Dicom Attributes to use 1. Slice Thickess 2. PixelSpacing (width, height) Calcuate new size out_size = [ int(np.round(original_size[0] * (original_spacing[0] / out_spacing[0]))), int(np.round(original_size[1] * (original_spacing[1] / out_spacing[1]))), int(np.round(original_size[2] * (original_spacing[2] / out_spacing[2]))..

Statistic methods np.sort np.min() & np.max() & np.median() np.percentile 더보기 calculate the ith percentile of the input numpy array along a specified axis ith percentile is the value at which i percent of the data is below it axis (default): input array is flattened np.histogram Find index or value np.where Change the shape np.squeeze 더보기 remove 1-dimensional axis np.tile transpose & reshape rav..

What is Thresholding? Thresholding is a type of image segmentation. It converts an image from colour or grayscale into a binary image that is simply black and white. Overall Process of Thresholding (fixed-level thresholding) 1) load the original image 2) convert it to grayscale - grayscale images containe pixel values in the range from 0 to 1 3) de-noise image ex.blurring - not necessary, but im..

What is difference between csv(.csv) and excel(.xls)? 1. CSV simple type of plain text file which uses a specific structure to arrange tabular data a newline terminates each row to begin the next row each column is separated by a comman within a row 2. Excel spreadsheet software included in the Microsoft office suite binary file that holds information about all the worksheets in a workbook Read ..
