Hello Everyone,
I am trying to work with lists and dictionaries together.
In the following code I have to access pixels in a segmented image through
a dictionary. But the problem is when I am trying to update the list
through dict it is giving me this error of tuple, ofcourse because list
indices should be integer.
THE CODE IS :
import cv
def access_segments(segimage, data):
print segimage
segments = {}
for y in xrange(0, segimage.height):
for x in xrange(0, segimage.width):
if segimage[y,x] == (0.0, 0.0, 0.0):
continue
else:
seg_color = segimage[y,x]
blue = int(seg_color[0])
green = int(seg_color[1])
red = int(seg_color[2])
reg_num = blue + 256 * green + 65536 * red
point = data[y,x]
segments.setdefault(reg_num, [])[point] += point
for p in sorted(segments.iterkeys()):
points = (segments[p])
print len(points)
print points
if __name__== "__main__":
data = cv.Load(r"C:\Users\inshu\Desktop\Masters
Thesis\data\xyz_00000.yml")
segimage = cv.LoadImageM(r"C:\Users\inshu\Desktop\Masters
Thesis\Segmentation\segmentation_numbers_00000.tif",
cv.CV_LOAD_IMAGE_UNCHANGED)
access_segments(segimage, data)
THE ERROR IS:
<cvmat(type=42424010 8UC3 rows=3000 cols=3000 step=9000 )>
Traceback (most recent call last):
File "C:\Users\inshu\Desktop\test_reading .py", line 27, in <module>
access_segments(segimage, data)
File "C:\Users\inshu\Desktop\test_reading .py", line 16, in
access_segments
segments.setdefault(reg_num, [])[point] += point
TypeError: list indices must be integers, not tuple
How can I access the data without getting this error ? the points have x,
y, z co-ordinates.
Thanks In Advance for your suggestions.
