Brings the power of OpenCV to TIFF videos; provides interface to multi-part TIFFs compatible with OpenCV's VideoCapture.
Provides a PIL based capture interface to multi-part tiffs, allowing them to be used more easily with OpenCV. This allows you to use OpenCV’s image and video processing capabilities with tiff stacks, a video form frequently encountered in scientific video as it is lossless and supports custom metadata.
A minimal example looks like this:
import tiffcapture as tc import matplotlib.pyplot at plt tiff = tc.opentiff(filename) plt.imshow(tiff.read()) plt.show() tiff.release()
More real world usage looks like this:
import tiffcapture as tc import cv2 tiff = tc.opentiff(filename) #open img _, first_img = tiff.retrieve() cv2.namedWindow('video') for f,img in tiff: tempimg = cv2.absdiff(first_img, img) # bkgnd sub _, tempimg = cv2.threshold(tempimg, 5, 255, cv2.cv.CV_THRESH_BINARY) # convert to binary cv2.imshow('video', tempimg) cv2.waitKey(80) cv2.destroyWindow('video')
