I converted both source and template to gray before.But, got same Error.. Now Its working...But, My template is not a gray.

So,This template and source is not same.

OpenCV docs said,

''image – Image where the search is running. It must be 8-bit or 32-bit floating-point.

templ – Searched template. It must be not greater than the source image and have the same data type.''

What type of data type mentioned in that docs?

code is added This question also in Stackoverflow http://stackoverflow.com/questions/40...

I'm trying to template matching using my web cam.I used web cam feed as source and used a template as small image that taken from web cam. Both template and source have same bit depth.(uint8).

I'm using OpenCV3.0 with python 2.7 in VS 2013 IDE I got this error:

C:\builds\master_PackSlaveAddon-win32-vc12-static\opencv\modules\imgproc\src\templmatch.cpp:1062: error: (-215) (depth == CV_8U || depth == CV_32F) && type == _templ.type() && _img.dims() <= 2 in function cv::matchTemplate

Code:

import cv2
import numpy as np

cam=cv2.VideoCapture(1)
template = cv2.imread("C:/Users/Nandika/Desktop/ttt.jpg",0)
w, h = template.shape[::-1]

method=cv2.TM_CCOEFF_NORMED

    while 1:
        _,img=cam.read()
        res = cv2.matchTemplate(img,template,method)
        min_val, max_val, min_loc, max_loc = cv2.minMaxLoc(res)

        # If the method is TM_SQDIFF or TM_SQDIFF_NORMED, take minimum
        if method in [cv2.TM_SQDIFF, cv2.TM_SQDIFF_NORMED]:
            top_left = min_loc
        else:
            top_left = max_loc
        bottom_right = (top_left[0] + w, top_left[1] + h)

        cv2.rectangle(img,top_left, bottom_right, 255, 2)

        cv2.imshow('img',img)


        if cv2.waitKey(1) & 0xFF == ord('q'):
            cv2.destroyAllWindow

Give me a solution

Thank in advance

import numpy as np

import cv2

img = cv2.imread('foo.jpg')

height, width, channels = img.shape

print height, width, channels

 600 800 3

did you say like this? http://docs.opencv.org/2.4/doc/tutori...

how to build opencv from src?

Hello,

My OS is windows 7 64bit. Python version 3.5.1 OpenCV version 3.1.0

I use VisualEtudio 2013 as IDE. First,I installed Visual Studio and then installed python.then I used PTVS(Python Tools For Visual Studio). python is working properly with VisualStudio.But,I cant use OpenCV in python. When I tried to run a code, following error is given from VisualStudio.

please help me to solve this problem and give me a suitable numpy link.

Thank in advance
