When I try to build opencv 2.4.11 with both c++ and python, an error comes up for python-
Traceback (most recent call last):
File "", line 1, in
ImportError: No module named numpy.distutils
The thing is numpy is installed for python 2.7.6 and not for python 2.7.9 which is what opencv is trying to build from.
How do I rectify this issue? How can I make opencv build particularly with python 2.7.6 or install numpy with python 2.7.9?

drawning labeling components in a image opencv c++
I have the next image.
I used the function connectedComponentsWithStats for find the components of the image. now i want draw only the components with an area > 3000, in this case there are 3 of the 5 components that the function found, i used the function "compare" for draw the 3 components but the result is not expected (only draw 1 component), Some idea for get the final result? thank you. my result is:
int main(int argc, const char** argv)
{
img = imread("blob.png", 0);
if (img.empty())
{
cout << "Could not read input image file: " << endl;
return -1;

Can OpenCV 3.1.0 be set to capture an RTSP stream over UDP?
Using OpenCV for Java, I've been trying to connect to an RTSP server that will transport video over UDP. The code looks like:
VideoCapture cam = new VideoCapture("rtsp://localhost:8554");
OpenCV sends a setup request to the RTSP server that looks like:
SETUP 127.0.0.1:8554/trackID=1
RTSP/1.0 Transport: RTP/AVP/TCP;unicast;interleaved=0-1
CSeq: 3
The server has to send data over UDP not TCP. I've tried passing in "rtsp://localhost:8554?udp" but that doesn't change the request sent. If I use OpenCV 3.0.0 the setup request that's sent looks like:
SETUP 127.0.0.1:8554/trackID=1
RTSP/1.0 Transport: RTP/AVP/UDP;unicast;client_port=744-7445
CSeq: 3
However, OpenCV 3.0.0 doesn't seem to have VideoWriter while OpenCV 3.1.0 does.
The discussion for a bug report, [RTSP over TCP with cvCreateFileCapture not working (Bug #2235)](http://code.opencv.org/issues/2235), mentions that there was a modification introduced in OpenCV 2.4.11 and 3.1.0, that forces VideoCapture to default to using TCP to transport media. Is data transport over TCP hard coded, or can VideoCapture be somehow set to use UDP?
Also, I tried having the RTSP server send "400 Bad Request" as a response to the TCP transport request, and OpenCV didn't send a follow up request for UDP. It just reported an error:

Split BGR into 3 separate images
I have used a couple of CV_32FC3 for processing and wish to convert one of the channels of each into CV_8UC1. I tried this:
Mat imgMedR(157, 78, CV_16UC3) ;
Mat imgMedL(157, 78, CV_16UC3) ;
Mat imgFiltR(157, 78, CV_32FC3) ;
Mat imgFiltL(157, 78, CV_32FC3) ;
medianBlur(imgLocsL, imgMedL, KernSize); //imgLocsL & imgLocsR work fine without the snippet shown
Scharr(imgMedL,imgFiltL, CV_32F, 1,0);
medianBlur(imgLocsR, imgMedR, KernSize);
Scharr(imgMedR,imgFiltR, CV_32F, 1,0);
Mat imgL(157, 78, CV_32FC1);
Mat imgR(157, 78, CV_32FC1);
Mat imgBGR_R[3],imgBGR_L[3];
split(imgFiltR, imgBGR_R);
split(imgFiltL, imgBGR_L);
imgR = imgBGR_R[3] / 64.0f;
imgL = imgBGR_L[3] / 64.0f; //Valgrind says I have a segment fault here but not the line above.
//the error identified is
imgR.convertTo(imgRight, CV_8U);
imgL.convertTo(imgLeft, CV_8U);
The Valgrind err messagesa re
Conditional jump or move depends on uninitialised value(s)
Use of uninitialised value of size 8
and
Invalid read of size 4
I confused. If imgLocsL and imgLocsR are OK, then the variables in the Mat at the offending line should have a valid value of type CV_32F.
If the error was after the converto, then I could save the image and look at it.
Anybody have any hints on how to troubleshoot this?
Thanks

How to convert Mat data to byte data in Andorid by using OpenCV
I'd like to convert Mat data to byte data by using OpencV.
My expected data format is the following:
ex.) data =[112,113,0,1,0,225,........] →1,0,225 is one layer CV_8UC3
but my code(System.outprint.ln(data)) is not equal to the above data format.
The Output value is "I/System.out: [B@43d1d008".
How should I achieve the problem?
My code:
・when I touch the screen, the Flag is to be set as "1";
then , in onCameraFrame, the Mat date is converted to byte data
and execute "System.outprint.ln" .

How to detect a perfect black image?
Hi,
This is my first post in this forum. I've written a color detection program for detecting Magenta color(only). But now I want to print a text when the magenta color is not present.Which means I want to detect a perfect black image for that.How can I do that?
import cv2
import numpy as np
cap = cv2.VideoCapture(0)
while(1):
# Take each frame
_, frame = cap.read()
# Convert BGR to HSV
hsv = cv2.cvtColor(frame, cv2.COLOR_BGR2HSV)
# define range of blue color in HSV
lower_blue = np.array([140,100, 140], dtype=np.uint8)
upper_blue = np.array([150,255,255], dtype=np.uint8)
# Threshold the HSV image to get only blue colors
mask = cv2.inRange(hsv, lower_blue, upper_blue)
# Bitwise-AND mask and original image
res = cv2.bitwise_and(frame,frame, mask= mask)
cv2.imshow('frame',frame)
cv2.imshow('mask',mask)
cv2.imshow('res',res)
k = cv2.waitKey(5) & 0xFF

How to convert String data ｔo byte data without Extra conversion
I asked a question a few hours ago , as the following but The intended question is changed.
http://answers.opencv.org/question/120726/how-to-convert-mat-data-to-byte-data-in-andorid-by-using-opencv/
So I newly ask a question in here.
[Question]
I would like to equal the value of "ds" to the value of "a" in the following code.
>･･･
>> Mat img2 = new Mat(new Size(85, 85),> CvType.CV_8UC3); String a = img2.dump(); > byte[] ds = a.getBytes();> System.out.println(a); -----(A)> System.out.println(ds);------(B)>･･･
Actually, (A) and (B) is different from each other
(A)'s output:
I/System.out: 244, 255, 249, 255, 243, 255, 248, 255, 247, 255, 245, ･･･
(B)'s output:
I/System.out: [B@4627b6a0 ･･･
The purpose of equaling the value of "ds" to the value of "a" is to send the ds's data via socket communication as the following:
>･･･ socket = new Socket(IP_ADDR,
> PORT); out = new> BufferedOutputStream(socket.getOutputStream());> out.write(ds); ･･･
then, I want not to send same value of (B) output but to send same value of (A) in byte data.
If you know the solution of the problem ,Please let me know.

}
When i make use of `UMat` to measure the performance, the performance with(UMat) or without(Mat) OpenCL did not make any difference.
I downloaded AMD-APP-SDK from this [link][1] and tried to build but there was no OpenCL binaries (instead i saw opengl dll files[glew32.dll & glut32.dll]. How do i build OpenCV with OpenCL by linking the OPENCL_LIBRARY?
