Code : import cv2, time a = 1 video = cv2.VideoCapture(0, cv2.CAP_DSHOW) while True: a = a + 1 check, frame

import cv2, time a = 1 video = cv2.VideoCapture(0, cv2.CAP_DSHOW) while True: a = a + 1 check, frame = video

import cv2, time a = 1 video = cv2.VideoCapture(0, cv2.CAP_DSHOW) while True: a = a + 1 check, frame = video

Thanks for the response berak

Thanks for the response, can I write some C++ code to call that method and use this feature from my Python code?

Python OpenCV OGL Texture2D Hello everyone, Based on https://stackoverflow.com/questions/18086519/is-it-possible-to-bin

Thank you cudawarped. It worked !!!

Sure cudawarped .I'll use this method ,but is it affect performance?

Hi all, I'm trying to adjust hsv in images with cv2.cuda. while trying when I use cv2.cuda.merge it returns numpy array and not GpuMat type.

my code :

import cv2
import numpy as np

img =  cv2.imread('test.png')
imgMat = cv2.cuda_GpuMat(img)
imgSat = cv2.cuda.cvtColor(imgMat,cv2.COLOR_BGR2HSV)
print("Before Merge type : ",type(imgSat))
h,s,v = cv2.cuda.split(imgSat)
size_s = s.size()
w_s = cv2.cuda_GpuMat(size_s[1],size_s[0], s.type(), [30])
s = cv2.cuda.add(s, w_s)
te = cv2.cuda.merge([h,s,v])
print("After merge type : ",type(te))

Output :

Before Merge type :  <class 'cv2.cuda_GpuMat'>
After merge type :  <class 'numpy.ndarray'>

Anyone facing same scenario?

Thanks cudawarped . but imgMat is already GpuMat img = cv2.imread('test.png') imgMat = cv2.cuda_GpuMat(img) after c

Image Stitching with cv2.cuda() Hi all, I have tried image stitching with opencv (followed https://www.pyimagesearch.com

Hi opencv.exe , do you got any solution for stitching with cuda?

Hi do you get any solution?

Your previous answer itself correct,I made a mistake in typo now corrected and executed it works.Thanks it's working goo

Thanks it's working good !!!!

Hi all, I'm trying to modify brightness and contrast of an Image but it returns the error

cv2.error: OpenCV(4.2.0-dev) F:\Dev\Repos\opencv_fork_1\modules\core\src\matrix_wrap.cpp:359: error: (-213:The function/feature is not implemented) getGpuMat is available only for cuda::GpuMat and cuda::HostMem in function 'cv::_InputArray::getGpuMat'

my code,

import time, traceback
import numpy
import cv2 as cv
import numpy as np
img = cv.imread('test.jpeg')
raw = cv.cuda_GpuMat()
raw.upload(img)
alpha = 50
beta = 45
b = raw.convertTo(cv.CV_8U,alpha,beta)
img = b.download()
cv.imshow("Corrected",img)

It's working thanks!!!!

I got this error when I tried your solution, cuMat8U = cv.cuda_GpuMat(img[:2],cv.CV_8UC3) TypeError: Expected Ptr<cv

I Don't know how to convert to the expected type

no , it's for map1.type = 13 and map2.type = 5
