I am trying to use a dicom image and manipulate it using OpenCV in a Python environment. So far I have used the pydicom library to read the dicom(.dcm) image data and using the pixel array attribute to display the picture using OpenCV imshow method. But the output is just a blank window. Here is the snippet of code I am using at this moment. import numpy as np import cv2 import pydicom as dicom ds=dicom.dcmread('sample.dcm') cv2.imshow('sample image dicom',ds.pixel_array) cv2.waitkey() If i print out the array which is used here, the output is different from what i would get with a normal numpy array. I have tried using matplotlib imshow method as well and it was able to display the image with some colour distortions. Is there a way to convert the array into a legible format for OpenCV?
