Requirements:
- Python 3;
- OpenCV3.
Installation:
- pip install lungs-finder
You can test your dataset using lungs_viewer.py.
It is a program that is displayed on the screenshot above.
Usage: lungs_viewer.py /your/dataset True
The last parameter defines whether labels will be displayed or not.
You can get lungs using HOG, Haar or LBP.
Example:
import lungs_finder as lf
image = cv2.imread("/your/image/cxr.png", 0)
# Get both lungs image. It uses HOG as main method,
# but if HOG found nothing it uses HAAR or LBP.
found_lungs = lf.get_lungs(image)
if found_lungs is not None:
cv2.imshow("Found lungs", found_lungs)
code = cv2.waitKey(0)
# Or you can get left or right lung independently using HOG, Haar or LBP.
right_lung_hog_rectangle = lf.find_right_lung_hog(scaled_image)
left_lung_hog_rectangle = lf.find_left_lung_hog(scaled_image)
right_lung_lbp_rectangle = lf.find_right_lung_lbp(scaled_image)
left_lung_lbp_rectangle = lf.find_left_lung_lbp(scaled_image)
right_lung_haar_rectangle = lf.find_right_lung_haar(scaled_image)
left_lung_haar_rectangle = lf.find_left_lung_haar(scaled_image)
if right_lung_hog_rectangle is not None:
x, y, width, height = right_lung_hog_rectangle
right_image = image[y:y + height, x:x + width]
cv2.imshow("Right lung", right_image)
code = cv2.waitKey(0)
