[Solved] What is the best way of learning Digital Image processing? [closed]

The only problem with MATLAB, for a beginner, is that it is really expensive. Some universities buy it without the Image Processing Toolbox, in which case it is not so useful. Octave is well supported by the open source community, that is another alternative “Processing” is a language that is easy to learn and powerful. … Read more

[Solved] how to save file image as original name

The reason you have the error is because the lists made by glob and os.listdir are not the same, either different files (glob is only getting jpg files and listdir gets everything) or different order, or both. You can change the filenames in a list, orig_files, to make a corresponding list of new filenames, new_files. … Read more

[Solved] How to search segment in picture

[Solved] conversion of matlab code to opencv code

There are many ways to do this. Most clean way would be setting ROI (Region of Interest) and then applying matrix operations. Something like: subtract(x(Rect(1,0,NumCols-1,NumRows)),x(Rect(0,0,NumCols-1,NumRows),R) singleLineMask = Mat(1,NumCols,CV_8U) for (int i=1;i<NumCols;i++) singleLineMask.at<int>(1,i)=1; repeat(singleLineMask,NumRows,1,MaskImage) d=mean(R,MaskImage) a=(8*mean(abs(R))-d)/7 assuming you create R and compute NumRows,NumCols prior to this operation and allocate MaskImage. 4 solved conversion of matlab code … Read more

[Solved] How can I access each pixel in OpenCV, perform an operation and return the new information to the image?

I think that this code you could use int nl= image.rows; int nc= image.cols * image.channels(); for (int j=0; j<nl; j++) { uchar* data= image.ptr<uchar>(j); for (int i=0; i<nc; i++) { data[i]= data[i]/div*div + div/2; } } solved How can I access each pixel in OpenCV, perform an operation and return the new information to … Read more

[Solved] trying to implement the canny edge using opencv on qt creator [closed]

I have made a small changes its perfectly working void MainWindow::edgeImage() { image =cvLoadImage(FileName.toLocal8Bit().data()); Gray = cvCreateImage(cvSize(image->width,image->height),IPL_DEPTH_8U,1 ); cvCvtColor(image, Gray, CV_RGB2GRAY); canny= cvCreateImage(cvSize(image->width,image->height),IPL_DEPTH_8U,1 ); cvCanny(Gray,canny,50,150,3); QImage imgCanny = QImage((const unsigned char*)canny->imageData,canny->width,canny->height,QImage::Format_Indexed8); imgCanny.setPixel(0,0,qRgb(0,0,0)); ui->label_3->setPixmap(QPixmap::fromImage(imgCanny).scaled(ui->label_3->size())); } solved trying to implement the canny edge using opencv on qt creator [closed]

[Solved] OCR – How to recognize numbers inside square boxes using python?

the code below for me is doing decent job but it’s hyper parameter sensitive : import cv2 import imutils import numpy as np import matplotlib.pyplot as plt from matplotlib import pyplot as plt def square_number_box_denoiser(image_path=”/content/9.png”,is_resize = False, resize_width = 768): ”’ ref : https://pretagteam.com/question/removing-horizontal-lines-in-image-opencv-python-matplotlib Args : image_path (str) : path of the image containing numbers/digits … Read more

[Solved] Unknown C++ statement

It’s a declaration of several variables in one line. Without obfuscation, it is equivalent to this: Mat gray; Mat smallImg( cvRound (img.rows/scale), cvRound(img.cols/scale), CV_8UC1 ); which shouldn’t need any further explanation. (In Ancient Times, when storage was sparse and terminals showed 24 lines of code, if you were lucky, using multiple-variable declarations made more sense … Read more

[Solved] This cpp code is for loading images using ls command.But it is not loading any image, even though it doesn’t show any error.plz help me to fix this [closed]

There are two major problems with your code. The first is that while (!feof(…)) will not work as you expect it to. That is because the EOF flag is not set until after you try to read beyond the end of the file for the first time. Instead do e.g. while (fgets(…) != NULL). The … Read more
