We have a number of internal image formats which I process in Matlab. I have read/write functions for all of them. For specificity, consider the TGA image format, for which there is a file exchange...

This is the part of my code that gives the problem. It is supposed to count the amount of green pixels in a picture: img = Image.open('path.tif') BLACK_MIN = np.array([0, 20, 20], np.uint8) BLACK...

I have configured OpenCV 3.1.0 in Eclipse Mars. These are my configuration, G++ includes: D:/opencv/build/install/include; GCC includes: D:/opencv/build/install/include Linker libraries: libopenc...

I loaded the image and tried to draw a red point in an image img=mpimg.imread('./images/im00001.jpg') red = [0,0,255] # Change one pixel img[ 0.,-26.10911452,0. ]=red imgplot = plt.imshow(img) b...

I use OpenCV 3.0 and Ubuntu 14.04. I'm trying to compile a few codes on Ubuntu using OpenCV. I get error "error: 'imread' is not a member of 'cv'" Due to my previous search knowledge, I...

Is it possible to load image in skimage (numpy matrix) format from URL without creating temporary file? skimage itself uses temporary files: https://github.com/scikit-image/scikit-image/blob/maste...

Using Python and OpenCV, I try to read an image which size is (3264*2448), but the resulting size is always (2448*3264). That means the direction of the image is changed by 90 degrees. The code is ...

I'm trying to load an image with OPENCV from an io.BytesIO() structure. Originally, the code loads the image with PIL, like below: image_stream = io.BytesIO() image_stream.write(connection.read(im...

I am trying to read an image in my C++ code LOGD("Loading image '%s' ...\n", (*inFile).c_str());; Mat img = imread(*inFile, CV_LOAD_IMAGE_GRAYSCALE); CV_Assert(img.data != 0); and get the follow...

I'm trying to load an image as grayscale as follows: from skimage import data from skimage.viewer import ImageViewer img = data.imread('my_image.png', as_gray=True) However, if I check for its ...

We have an OpenCV problem of opening (and writing) file paths that contain non-ASCII characters on Windows. Affected functions are: cv::imread(), cv::imwrite(), ... As far as I saw in the OpenCV so...

I am getting a bit confused with the flags that cv::imread takes. My goal is to load images that have an alpha channel with this alpha channel (i.e. as CV_8UC4). At the same time I want to load th...

I want to read an image from a qrc using imread() of OpenCV in this way: Mat img = imread(":/TempIcons/logo.png"); but the final img size is [0x0]. I have also tried: Mat img = imread("qrc://Te...

I have encountered a problem with the function imread() in Matlab (2014) and OpenCV (3.0) on Windows 7 with jpg files. I don't have the same values by reading the same file jpg and the same pixel....

When I read an image using opencv imread function, I find its height and width being swapped as what it should be. Like my original image is of dimensions (610 by 406) but on being read using openc...

I am extremely new to scikit-image (skimage) library in Python for image processing (started few minutes ago!). I have used imread to read an image file in a numpy.ndarray. The array is 3 dimension...

I have a .tar file containing several hundreds of pictures (.png). I need to process them via opencv. I am wondering whether - for efficiency reasons - it is possible to process them without pass...
