Hello, I try do background subtraction using python, and I have problem to
save each pixel to jagged array...
*My jagged array is:*
m_samples=[]
height, width, depth=cap.shape
c_black=np.zeros( (height,width), dtype=np.uint8)
for i in range(0,NUM_SAMPLES,1):
m_samples.appe
Please help me... I'm using python 2.7.6, numpy 1.8.1, opencv 2.4.9..
I want to get pixel value in one number like 255 not each value like these
R(190), G(23), B(45) from coordinate (x,y)...
I try these code
m_samples[k][i][j]=getPixel(img,row,col)
But get error:
NameError: name 'getPixel' is not
I'm so sorry for late reply, my laptop broken, the code actually I already
put in thread before so I'll copy to here..
I don't know how to get pixel, I just searched and many link using
'getPixel' to get value of pixel..
I know color frame using 3 channel B G R to get pixel, but I just want to
get
Hello, I'm trying to counting vehicle, but I can't increasing it, I use
python 2.7.6 and opencv 2.4.9
Here the code:

bgsMOG = cv2.BackgroundSubtractorMOG2(500,30,True)
cap = cv2.VideoCapture("d:\MOV_5680.avi")
counter=0
if cap:
while True:
ret, frame = cap.read(

>What is the value of y here?
(x,y,w,h)=cv2.boundingRect(contour), where x,y is the left up position from
contour, and w,h is width and height of contour..
>* if w > 10 and h > 15:*
*this code I used, because there's a lot small blob from video
shaking, or the movement of trees..
There's no vehicle in my code, my video just contain vehicles so I think I
don't need to use haar classifier, so I'm just do background subtraction to
get foreground which is vehicle movement because there's no other movement
except vehicle and maybe little movement from trees...
I just use opencv
If all of these confusing, I'll simplify the problem, I need to know
if a point (x,y) exactly at a line where line is (ax1,ay) to
(ax2,ay)..
Can someone tell me how??

If I have array a=[[60,70,1],[43,54,2],[87,67,3],[90,89,4],[12,4,5]] where
[x,y,id] and I want to find if x=87 and y=67, and find which row is it,and
I need to edit the id column with new value..
I can search in first column using:
if (x in a[:,0]):
print('yes')
how I can know index row so I
10 matches
